Description

ガスタービン発電装置、ガスタービン発電システムおよびその制御方法Gas turbine power generation apparatus, gas turbine power generation system and control method thereof
　本発明は、ガスタービンによる発電装置において、特に、高湿分空気を利用する高湿分ガスタービンサイクル発電設備のガスタービン発電装置、ガスタービン発電システムおよびその制御方法に関する。 The present invention relates to a gas turbine power generation apparatus, and more particularly to a gas turbine power generation apparatus, a gas turbine power generation system, and a control method thereof for a high-humidity gas turbine cycle power generation facility using high-humidity air.
　火力発電プラントには、燃焼器によってガスを燃焼させ、その高温高圧な燃焼ガスによってガスタービンを回転駆動させて発電するガスタービン発電装置や、ガスタービンで燃焼した排ガスを利用し、排熱回収ボイラにて蒸気を発生させ、その蒸気にて蒸気タービンを回転駆動させるコンバインドサイクル発電装置がある。 Thermal power plants use gas turbine power generators that generate gas by combusting gas with a combustor and rotating the gas turbine with the high-temperature and high-pressure combustion gas, and exhaust heat recovery boilers using exhaust gas combusted in the gas turbine. There is a combined cycle power generation device that generates steam and rotates the steam turbine with the steam.
　何れの装置にもガスタービンが備わっているが、ガスタービンの出力は、入口側吸気温度が高くなると燃焼ガスの質量流量が少なくなり、低下することが知られている。従って、外気温度が高くなる夏季での運用や、もともと外気温度の高い地域での運用では、燃焼ガスの質量流量が少なくなることから、定格出力を下回ることもある。その為、圧縮器入口で水を噴霧することでガスタービンの入口側吸気温度を低下させて質量流量の低下を防ぎ、外気温度の高い場合でも、定格出力を維持するための装置や方法が考案されている。 Although any apparatus is equipped with a gas turbine, it is known that the output of the gas turbine decreases as the inlet side intake air temperature increases and the mass flow rate of the combustion gas decreases. Accordingly, in operation in summer when the outside air temperature is high or in operation in a region where the outside air temperature is originally high, the mass flow rate of the combustion gas is reduced, so that it may be lower than the rated output. Therefore, by spraying water at the compressor inlet, the intake temperature on the inlet side of the gas turbine is reduced to prevent the mass flow rate from decreasing, and devices and methods for maintaining the rated output even when the outside air temperature is high are devised. Has been.
　一方、近年、二酸化炭素低減の観点から自然エネルギを利用した発電が注目されている。
　特に、太陽光発電あるいは太陽熱を利用した発電が急速に広まっている。前者は、大容量の発電を得るために広大な設置スペースが必要となる。後者は、単独での発電よりは、既設の発電プラントへの熱供給利用という範囲にとどまっている。
　従来技術としては、ガスタービンの燃焼排ガスの熱エネルギを回収し得られた蒸気をガスタービン燃料用の空気に混入し燃焼器で得られた高湿分の燃焼排ガスでタービンを駆動することで、出力および発電効率の向上を実現するガスタービンサイクルがある。 On the other hand, in recent years, power generation using natural energy has attracted attention from the viewpoint of reducing carbon dioxide.
In particular, photovoltaic power generation or power generation using solar heat is rapidly spreading. The former requires a large installation space in order to obtain a large-capacity power generation. The latter is limited to the use of heat supply to existing power plants rather than power generation alone.
As a prior art, by driving the turbine with the high-humidity combustion exhaust gas obtained by the combustor by mixing the steam obtained by recovering the thermal energy of the combustion exhaust gas of the gas turbine into the air for the gas turbine fuel, There are gas turbine cycles that provide improved power and power generation efficiency.
　また、下記の特許文献１には、圧縮機の入口に導入される吸気中に液滴を噴霧して出力の向上と熱効率の向上を図る技術が開示されている。 Also, the following Patent Document 1 discloses a technique for improving the output and the thermal efficiency by spraying droplets in the intake air introduced into the inlet of the compressor.
特開平９－２３６０２４号公報JP-A-9-236024
　ところで、ガスタービンで所望の出力あるいは発電効率を得るためには、その入口側吸気温度を低下させ燃焼空気の質量流量が少なくなるのを抑制し、燃焼器に供給される圧縮空気に大量の水を注入する必要がある。しかしながら、これによって、燃焼器での燃焼に不安定が生じる。特に、ガスタービンを用いた発電装置では、高温高圧での燃焼に伴う燃焼排ガスに含まれるNOxを低減させるべく、安定燃焼範囲の狭い空気と燃料の予混合燃焼を行うため影響が大きい。 By the way, in order to obtain a desired output or power generation efficiency in the gas turbine, it is possible to suppress a reduction in the mass flow rate of the combustion air by lowering the inlet side intake air temperature, and to add a large amount of water to the compressed air supplied to the combustor. Need to be injected. However, this causes instability in combustion in the combustor. In particular, in a power generator using a gas turbine, in order to reduce NOx contained in combustion exhaust gas accompanying combustion at high temperature and pressure, the influence is large because premixed combustion of air and fuel having a narrow stable combustion range is performed.
　前記の従来技術のガスタービンサイクルでは、大量の水を利用するため、この問題に対応するのは困難である。一方、特許文献１では、圧縮機の入口に導入される吸気中に液滴を噴霧することで、出力の向上と熱効率の向上を図れるが、更なる出力の向上と熱効率の向上が望まれる。 In the conventional gas turbine cycle, a large amount of water is used, so it is difficult to cope with this problem. On the other hand, in Patent Document 1, it is possible to improve the output and the thermal efficiency by spraying droplets in the intake air introduced into the inlet of the compressor. However, further improvement in the output and the thermal efficiency are desired.

　図１は、実施形態に係るガスタービン発電装置１００の概念的構成図である。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a conceptual configuration diagram of a gas turbine power generator 100 according to an embodiment.
　ガスタービン発電装置１００は、発電のための基本構成要素として、吸入した空気を圧縮して高圧にした圧縮空気を出力する圧縮機２と、圧縮器２から供給される圧縮空気と燃料を燃焼する燃焼器４と、圧縮器２からの燃焼(排)ガスで回転駆動するガスタービン１と、ガスタービン１にガスタービン軸１ａを介して連結されガスタービン１の運動エネルギを電気エネルギに変換する発電機３とを備えている。 The gas turbine power generation apparatus 100 combusts the compressed air and fuel supplied from the compressor 2 as a basic component for power generation, and outputs compressed air that is compressed into high pressure by compressing the sucked air. A combustor 4, a gas turbine 1 that is rotationally driven by combustion (exhaust) gas from the compressor 2, and power generation that is connected to the gas turbine 1 via a gas turbine shaft 1 a and converts the kinetic energy of the gas turbine 1 into electrical energy. Machine 3.
　また、ガスタービン発電装置１００は、発電出力および発電効率の向上のために使用する温水を得るための構成要素として、給水を行う給水ポンプ５と、該給水をガスタービン１から排出される排ガスの熱を用いて加熱する給水加熱器６と、太陽の日照で得られる熱を集熱する太陽集熱装置７および該集熱した熱によって給水ポンプ５から送られる給水を加熱する集熱管８とを備えている。 In addition, the gas turbine power generation apparatus 100 includes, as components for obtaining hot water used for improving power generation output and power generation efficiency, a water supply pump 5 that supplies water and exhaust gas discharged from the gas turbine 1. A feed water heater 6 that heats using heat, a solar heat collecting device 7 that collects heat obtained by solar sunshine, and a heat collecting tube 8 that heats feed water sent from the feed water pump 5 by the collected heat. I have.
　そして、ガスタービン発電装置１００は、温水を用いるための構成要素として、集熱管８および／または給水加熱器6で加熱された温水にて圧縮器２の吸気を冷却する吸気冷却室９と、温水を吸気冷却室９内で噴霧する噴霧ノズル１０と、温水を蒸発させ燃焼器４に投入する蒸発器１１と、圧縮器２の出口から排出される高温(例えば、約４００℃)のガスタービン１のタービン翼の冷却用空気を冷却水に加えて当該温水(約１５０℃～１８０℃程度)を用いて冷却するインタークーラ１２とを備えている。 The gas turbine power generation apparatus 100 includes an intake air cooling chamber 9 that cools the intake air of the compressor 2 with hot water heated by the heat collecting pipe 8 and / or the feed water heater 6 as components for using hot water, A spray nozzle 10 that sprays the inside of the intake air cooling chamber 9, an evaporator 11 that evaporates hot water and throws it into the combustor 4, and a high-temperature (for example, about 400 ° C.) gas turbine 1 that is discharged from the outlet of the compressor 2. And an intercooler 12 for cooling the turbine blades with the hot water (about 150 ° C. to 180 ° C.) by adding cooling air to the turbine blades to the cooling water.
　次に、本ガスタービン発電装置１００にて発電出力および発電効率が向上する作用(現象)について説明する。
　集熱管８および／または給水加熱器6で加熱した温水を吸気冷却室９内にある噴霧ノズル１０から吸気冷却室９内に噴霧することで、その一部が蒸発して蒸発潜熱により空気が冷却される。ここで、空気は冷却されると分子の運動エネルギが低下し密度が高くなる。
　冷却された空気は吸気冷却室９から圧縮器２に入る。 Next, the action (phenomenon) of improving the power generation output and power generation efficiency in the gas turbine power generation apparatus 100 will be described.
By spraying the hot water heated by the heat collecting pipe 8 and / or the feed water heater 6 from the spray nozzle 10 in the intake cooling chamber 9 into the intake cooling chamber 9, a part thereof is evaporated and the air is cooled by latent heat of evaporation. Is done. Here, when air is cooled, the kinetic energy of molecules decreases and the density increases.
The cooled air enters the compressor 2 from the intake cooling chamber 9.
　冷却された空気は密度が高くなることから、圧縮器２に入る空気の質量流量が増加する。この効果によって、タービン翼(図示せず)に当たる圧縮器２からの燃焼(排)ガスの質量が増加してタービン翼に与えられる運動エネルギが増加する。これにより、ガスタービン１の回転駆動力が大きくなり、ガスタービン１の出力が増加する。
　従来、用いていた水に比較した場合の温水を利用することの利点(メリット)は、温水を吸気冷却室９内に噴霧することで減圧による沸点の低下で減圧沸騰が生じ、噴霧される液滴が一層微粒子化する。このため、より多くの噴霧水(温水)を噴霧することができ、更に質量流量が増加する。この結果、温水を噴霧することで、更なる出力向上を得ることが可能となる。なお、本実施形態では、減圧沸騰が生じ易い温水の温度として、約１５０℃～１８０℃を想定している。 Since the density of the cooled air increases, the mass flow rate of the air entering the compressor 2 increases. Due to this effect, the mass of combustion (exhaust) gas from the compressor 2 impinging on the turbine blade (not shown) increases, and the kinetic energy given to the turbine blade increases. Thereby, the rotational driving force of the gas turbine 1 is increased, and the output of the gas turbine 1 is increased.
The advantage (merit) of using warm water in comparison with the conventionally used water is that the boiling water is sprayed in the intake air cooling chamber 9 due to the lowering of the boiling point due to the reduced pressure, and the sprayed liquid. The droplets become finer. For this reason, more spray water (hot water) can be sprayed, and the mass flow rate further increases. As a result, further output improvement can be obtained by spraying warm water. In the present embodiment, it is assumed that the temperature of hot water at which reduced-pressure boiling easily occurs is about 150 ° C. to 180 ° C.
　また、温水を蒸発器１１に通すことで得られる蒸気を燃焼器４に噴射することにより、燃焼器４からガスタービン１に入る質量流量を増やすことができるため、この効果によって、ガスタービン１の出力が増加する。
　加えて、圧縮器２から排出される空気(約４００℃)を、インタークーラ１２において温水(約１５０℃～１８０℃)の蒸発潜熱で再冷却し、インタークーラ１２から供給されるタービン翼を冷却するための空気の量である冷却空気量を低減する。 Moreover, since the mass flow rate which enters into the gas turbine 1 from the combustor 4 can be increased by injecting the steam obtained by letting warm water through the evaporator 11 to the combustor 4, the effect of the gas turbine 1 can be increased. Output increases.
In addition, the air discharged from the compressor 2 (about 400 ° C.) is recooled by the latent heat of evaporation of hot water (about 150 ° C. to 180 ° C.) in the intercooler 12 to cool the turbine blades supplied from the intercooler 12. The amount of cooling air that is the amount of air to be reduced is reduced.
　このように、温水を用いるインタークーラ１２での冷却用空気の冷却により、圧縮器２の出口から排出される冷却用空気(例えば、約４００℃)が温水(約１５０℃～１８０℃程度)で冷却されるため、インタークーラ１２で冷却用空気を冷却するための冷却水を用いるエネルギを節約できる。また、冷却用空気が従来より低温になるために冷却用空気量が低減される。
　従って、従来に比べインタークーラ１２で圧縮器２の出口から排出される空気を冷却するために必要とされるエネルギが低減され、ガスタービン発電装置１００の発電効率が向上する。 Thus, the cooling air (for example, about 400 ° C.) discharged from the outlet of the compressor 2 is warm water (about 150 ° C. to about 180 ° C.) by cooling the cooling air in the intercooler 12 using hot water. Since it cools, the energy using the cooling water for cooling the cooling air by the intercooler 12 can be saved. In addition, since the cooling air has a lower temperature than before, the amount of cooling air is reduced.
Therefore, the energy required for cooling the air discharged from the outlet of the compressor 2 by the intercooler 12 is reduced as compared with the conventional case, and the power generation efficiency of the gas turbine power generator 100 is improved.

＜関連情報データベース３００の情報＞
　次に、関連情報データベース３００に格納されている計測信号１２０の情報、運転条件判定用データについて説明する。
　始めに、ガスタービン発電装置１００から得られる計測信号１２０の情報について説明する。
　図３は関連情報データベース３００に保存されている計測信号１２０に係わる情報の態様を示す図である。 <Information of related information database 300>
Next, the information of the measurement signal 120 and the operation condition determination data stored in the related information database 300 will be described.
First, the information of the measurement signal 120 obtained from the gas turbine power generator 100 will be described.
FIG. 3 is a diagram showing an aspect of information related to the measurement signal 120 stored in the related information database 300.
　ガスタービン発電装置１００において各種の計測器で計測した情報が、図３に示すように、計測器毎(図３の縦列)に各計測時刻(図３の横列)と共に保存される。
　ＰＩＤ番号とは、関連情報データベース３００に格納されているデータを容易に識別または活用できるように、各計測器の計測値に割り付けられた固有の番号である。
　ＰＩＤ番号の下にあるアルファベットは、被計測対象の物理量が何であるかを示す記号である。例えば、集熱管８および／または給水加熱器６で作られる温水の流量値Ｆ、温水の温度値Ｔ、温水の圧力値Ｐ、発電出力値Ｅ、燃焼器４の燃焼(排)ガスに含まれるNOxの濃度値Ｄである。なお、図３では１秒周期でデータを保存する場合を例示しているが、データ収集のサンプリング周期は対象となるガスタービン発電装置１００によって異なる。 As shown in FIG. 3, information measured by various measuring instruments in the gas turbine power generation apparatus 100 is stored for each measuring instrument (column in FIG. 3) together with each measurement time (row in FIG. 3).
The PID number is a unique number assigned to the measurement value of each measuring instrument so that the data stored in the related information database 300 can be easily identified or utilized.
The alphabet below the PID number is a symbol indicating what the physical quantity to be measured is. For example, it is included in the flow rate value F of warm water produced by the heat collecting pipe 8 and / or the feed water heater 6, the temperature value T of warm water, the pressure value P of warm water, the power generation output value E, and the combustion (exhaust) gas of the combustor 4. This is the NOx concentration value D. In addition, although the case where data is preserve | saved at a 1 second period is illustrated in FIG. 3, the sampling period of data collection changes with the gas turbine power generator 100 used as object.
　次に、ガスタービン発電装置１００の運転条件を判定する際に必要となる情報について説明する。
　図４は、ガスタービン発電装置１００の周辺の気候状態の実測値および予測値の情報の様式を示した図であり、図４(ａ)は実測値を示し、図４(ｂ)は予測値を示す。
　なお、図４に示す実測値および予測値は、関連情報データベース３００に格納されるが、制御装置２００の一時記憶エリア(ワークエリア)に記憶するようにしてもよい。 Next, information necessary for determining the operating condition of the gas turbine power generation device 100 will be described.
FIG. 4 is a diagram showing a format of information on measured values and predicted values of the climatic state around the gas turbine power generation apparatus 100. FIG. 4 (a) shows the measured values and FIG. 4 (b) shows the predicted values. Indicates.
4 are stored in the related information database 300, but may be stored in a temporary storage area (work area) of the control device 200.
　図４に示す実測値および予測値とも、時間(時刻)、天気、気温(摂氏)、風向、風速、湿度(相対湿度)、日射量を含んで格納されている。
　時間(時刻)の周期は、計測可能な時間幅により決定される。天気は、例えば、気象庁が一般向けに発信している１５種類を用いて表現する。１５種類とは、快晴、晴れ、薄曇り、曇り、煙霧、砂塵嵐、地吹雪、霧、霧雨、雨、みぞれ、雪、あられ、ひょう、雷である。
　風向きは日本では1６方位を用いるのが一般的であるが、国際式では、真北を基準とし、時計回りの方向に３６０度に分割して表現する３６０方位が用いられている。図４中では、３６０方位で表現しているが、１６方位においてもそれぞれの方位に対して２２．５度の割合を与えて表現すれば、同様に度で数値化できる。 The actual measurement value and the predicted value shown in FIG. 4 are stored including time (time), weather, temperature (Celsius), wind direction, wind speed, humidity (relative humidity), and solar radiation.
The period of time (time) is determined by a measurable time width. The weather is expressed using, for example, 15 types transmitted by the Japan Meteorological Agency to the general public. The 15 types are clear, clear, light cloudy, cloudy, haze, dust storm, blizzard, fog, drizzle, rain, sleet, snow, hail, hail, and thunder.
In Japan, the wind direction is generally 16 azimuths. However, in the international style, 360 azimuths expressed by dividing 360 degrees in the clockwise direction on the basis of true north are used. In FIG. 4, it is expressed by 360 azimuths, but even in 16 azimuths, if expressed by giving a ratio of 22.5 degrees to each azimuth, it can be quantified in degrees as well.
　図４(ａ)の実測値データテーブルには、実際に実測されたそれぞれの数値が格納される。
　図４(ｂ)の予測値データテーブルには、例えば予測モデルでの計算結果や、気象庁や気象会社などからの配信データを基にそれぞれの数値が格納される。場所によっては、現在、１時間毎に、時間(時刻)、天気、気温(摂氏)、風向、風速などの各数値を配信している場合もあるが、それ以外では、過去のデータを基に予測値を計算するモデルが必要となる。 Each actually measured value is stored in the actually measured value data table of FIG.
In the predicted value data table of FIG. 4B, respective numerical values are stored based on, for example, a calculation result in a prediction model and distribution data from the Japan Meteorological Agency or a weather company. Depending on the location, the hour (time), weather, temperature (degrees Celsius), wind direction, wind speed, etc. may be distributed every hour, but otherwise, based on past data. A model for calculating the predicted value is required.
　この予測モデルには、例えば、物理式を基に大気の状態を予測するためのモデルであるメソ気象モデルWRF(Weather Research and Forecasting)modelがある。本モデルでは、所望の地域を予報するための設定が必要なため、過去のデータを基に回帰式などを用いて、簡易的に求める方法もある。ここでは、何れの方式であっても構わない。
　なお、図４(ａ)の実測値データテーブルおよび図４(ｂ)の予測値データテーブルは外気の状態情報の一例を示したものであり、その他の表現を用いてもよいのは勿論である。
　また、関連情報データベース３００に格納される情報は、必要に応じて適宜、一時記憶領域(ワークエリア)に記憶するように構成してもよい。 This prediction model includes, for example, a meso-meteorological model WRF (Weather Research and Forecasting) model, which is a model for predicting atmospheric conditions based on physical formulas. In this model, since it is necessary to make a setting for forecasting a desired region, there is also a simple method of obtaining using a regression equation or the like based on past data. Here, any method may be used.
It should be noted that the actual measurement value data table in FIG. 4A and the predicted value data table in FIG. 4B show an example of outside air state information, and other expressions may of course be used. .
The information stored in the related information database 300 may be configured to be stored in a temporary storage area (work area) as necessary.
　図５は、関連情報データベース３００に格納されている図４(ｂ)に示す予測値データテーブルに格納されているデータを用いて、集熱管８から吐出される温水の温度を推定するニューラルネットワークのモデルを示す図である。
　ニューラルネットワークのモデルは、入力層、中間層、出力層を持ち、それぞれの層には、複数のノード(図５中、○で示す)が備わっている。これらのノードは、入力層から出力層に向かって、リンクされており、リンクの強さを表す重み係数が設定されている。つまり、重み係数はノード間の連結数だけ存在する。本ニューラルネットワークのモデルは、人間の持つ脳神経ネットワークを模擬したものである。 FIG. 5 shows a neural network that estimates the temperature of hot water discharged from the heat collecting pipe 8 using data stored in the predicted value data table shown in FIG. 4B stored in the related information database 300. It is a figure which shows a model.
The neural network model has an input layer, an intermediate layer, and an output layer, and each layer includes a plurality of nodes (indicated by ◯ in FIG. 5). These nodes are linked from the input layer to the output layer, and a weighting coefficient representing the strength of the link is set. That is, there are as many weighting coefficients as the number of connections between nodes. The model of this neural network simulates a human cranial nerve network.
　本モデルに、入力値を与え、その入力値に対する所望の出力値が出力されるよう重み係数を調整することで、入力値のもつ相関関係をモデルとして表現できるようになる。この重み係数を調整する過程を学習と呼んでいる。学習が完了すると重み係数が決まるので、本モデルに入力値を入力することで、その時の入力値のもつ重み係数に依る相関関係をもとに、出力値を推定することが可能となる。ノードに設定する関数はシグモイド関数と呼ばれる指数関数を用いるのが一般的であるが、それに限定するものではない。また、学習時に、重み係数を適切に調整するアルゴリズムは多数考案されている。一般的には、バックプロパゲーション法を用いる。これらの詳しい計算アルゴリズムについては、「基礎と実践　ニューラルネットワーク、臼井支朗他著、コロナ社」に詳しい。 与 え By giving an input value to this model and adjusting the weighting coefficient so that the desired output value for the input value is output, the correlation of the input value can be expressed as a model. The process of adjusting this weighting factor is called learning. When the learning is completed, the weighting coefficient is determined. By inputting an input value into this model, it is possible to estimate the output value based on the correlation depending on the weighting coefficient of the input value at that time. The function set for the node is generally an exponential function called a sigmoid function, but is not limited thereto. In addition, many algorithms have been devised that appropriately adjust the weighting factor during learning. In general, the back propagation method is used. For details on these calculation algorithms, see "Basics and Practice, Neural Networks, Shiro Usui et al., Corona, Inc.".
＜制御装置２００の運転条件判定部４００と制御部５００での演算機能＞
　次に、図２に示す制御装置２００における運転条件判定部４００での演算機能の動作について説明する。
　図６に、運転条件判定部４００での動作(処理)をフローチャートにて示す。
　始めに、Ｓ(ステップ)４０１では、太陽集熱装置７があるか否かを、入力装置９００からの入力情報やガスタービン発電システムＳへの設定情報などから判断する。あればステップ４０２へ、なければステップ４０９に進む。 <Calculation Function in Operation Condition Determination Unit 400 and Control Unit 500 of Control Device 200>
Next, the operation of the calculation function in the operating condition determination unit 400 in the control device 200 shown in FIG. 2 will be described.
FIG. 6 is a flowchart showing the operation (processing) in the operating condition determination unit 400.
First, in S (step) 401, it is determined whether or not there is the solar heat collecting device 7 from input information from the input device 900, setting information to the gas turbine power generation system S, and the like. If yes, go to Step 402, otherwise go to Step 409.
　太陽集熱装置７があると判断された場合(Ｓ４０１でＹｅｓ)、Ｓ４０２で、ガスタービン１の排ガスによる熱を用いて給水を加熱して温水を生成できる給水加熱器６があるか否かを、入力装置９００からの入力情報やガスタービン発電システムＳへの設定情報などから判定する。
　給水加熱器６があると判定された場合(Ｓ４０２でＹｅｓ)、Ｓ４０３へ進み、図５で示したモデルを用いて、現在の気温や日射量から太陽集熱装置７の太陽熱による温水の温度の推定値が減圧沸騰の効果を得る設定温度(例えば、約１５０℃～１８０℃)以上で温水が供給可能か否かを判定する。なお、温水による減圧沸騰の効果を得るためには、１５０℃を温水の温度の設定温度とするのが適しているが、発電設備のガスタービン発電装置１００の状況によって、本設定温度は多少前後する。また、温水は、実際に使用される箇所で適温、例えば１５０℃になるように流量などを増減して調整すればよい。 When it is determined that there is the solar heat collecting device 7 (Yes in S401), in S402, it is determined whether or not there is a feed water heater 6 that can generate hot water by heating the feed water using heat from the exhaust gas of the gas turbine 1. The determination is made based on the input information from the input device 900 and the setting information for the gas turbine power generation system S.
When it is determined that there is the feed water heater 6 (Yes in S402), the process proceeds to S403, and the temperature of the hot water due to the solar heat of the solar heat collecting device 7 is calculated from the current temperature and the amount of solar radiation using the model shown in FIG. It is determined whether hot water can be supplied when the estimated value is equal to or higher than a set temperature (for example, about 150 ° C. to 180 ° C.) at which the effect of boiling under reduced pressure is obtained. In order to obtain the effect of boiling under reduced pressure with hot water, it is suitable to set the temperature of 150 ° C. as the temperature of the hot water, but this set temperature is slightly different depending on the situation of the gas turbine power generation device 100 of the power generation facility. To do. Further, the hot water may be adjusted by increasing or decreasing the flow rate so as to be an appropriate temperature at a place where it is actually used, for example, 150 ° C.
　太陽集熱装置７の集熱管８の太陽熱による温水の温度の推定値が設定温度以上で供給可能であると判定された場合(Ｓ４０３でＹｅｓ)、Ｓ４０４へ進み、太陽集熱装置７による温水および給水加熱器６のガスタービン１の排ガスの加熱による温水の両方が供給可能であるので、太陽集熱温水のフラグおよび排ガス加熱温水のフラグはともに“１”が設定される。 When it is determined that the estimated value of the temperature of the hot water by the solar heat of the heat collecting tube 8 of the solar heat collecting device 7 can be supplied at a set temperature or higher (Yes in S403), the process proceeds to S404, and the hot water by the solar heat collecting device 7 and Since both hot water by heating the exhaust gas of the gas turbine 1 of the feed water heater 6 can be supplied, both the solar heat collecting hot water flag and the exhaust gas heating hot water flag are set to “1”.
　一方、Ｓ４０３で、太陽集熱装置７の集熱管８の太陽熱による温水の温度の推定値が設定温度以上で供給可能でないと判定された場合(Ｓ４０３でＮｏ)、Ｓ４０５に進み、太陽集熱装置７の太陽熱による温水を供給できないため、太陽集熱温水のフラグに“０”が設定され、排ガス加熱温水のフラグに“１”が設定される。 On the other hand, when it is determined in S403 that the estimated value of the temperature of the hot water by the solar heat of the heat collecting tube 8 of the solar heat collecting device 7 cannot be supplied above the set temperature (No in S403), the process proceeds to S405, where the solar heat collecting device Since hot water by solar heat 7 cannot be supplied, “0” is set in the flag of the solar heat collecting hot water, and “1” is set in the flag of the exhaust gas heating hot water.
　Ｓ４０２で、給水加熱器６がないと判定された場合(Ｓ４０２でＮｏ)、Ｓ４０６に進み、太陽集熱装置７のみが設置されている状況で、太陽熱による温水の温度の推定値が前記の減圧沸騰の効果を得る設定温度(例えば、約１５０℃～１８０℃)以上で供給可能であるか否か判定される。
　太陽集熱装置７のみが設置されている状況で、太陽熱による温水の温度の推定値が設定温度以上で供給可能であると判定された場合(Ｓ４０６でＹｅｓ)、ステップ４０７へ進み、太陽集熱装置７の太陽熱による温水のみ供給可能となるため、太陽集熱温水のフラグに“１”が設定され、排ガス加熱温水のフラグに“０”が設定される。 If it is determined in S402 that there is no feed water heater 6 (No in S402), the process proceeds to S406, and in the situation where only the solar heat collecting device 7 is installed, the estimated value of the temperature of the hot water by solar heat is the reduced pressure. It is determined whether supply is possible at a set temperature (for example, about 150 ° C. to 180 ° C.) or higher at which the boiling effect is obtained.
When it is determined that only the solar heat collecting device 7 is installed and the estimated value of the temperature of the hot water by the solar heat can be supplied at the set temperature or more (Yes in S406), the process proceeds to step 407, and the solar heat collecting device Since only hot water by the solar heat of the device 7 can be supplied, “1” is set in the flag of the solar heat collecting hot water, and “0” is set in the flag of the exhaust gas heating hot water.
　一方、Ｓ４０６で、太陽集熱装置７のみが設置されている状況で、太陽熱による温水の温度の推定値が設定温度以上で供給可能でないと判定された場合(Ｓ４０６でＮｏ)、Ｓ４０８へ進み、全ての温水が利用不可となるため、太陽集熱温水のフラグに“０”が設定され、かつ、排ガス加熱温水のフラグに“０”が設定される。
　Ｓ４０１で、太陽集熱装置７がないと判断された場合(Ｓ４０１でＮｏ)、Ｓ４０９に進み、ガスタービン１の排ガスの加熱による給水加熱器６があるか否か判定される。 On the other hand, when it is determined in S406 that only the solar heat collecting device 7 is installed and it is determined that the estimated value of the temperature of the hot water by solar heat cannot be supplied at the set temperature or higher (No in S406), the process proceeds to S408. Since all the hot water is unavailable, “0” is set in the flag of the solar heat collecting hot water, and “0” is set in the flag of the exhaust gas heating hot water.
If it is determined in S401 that there is no solar heat collector 7 (No in S401), the process proceeds to S409, where it is determined whether there is a feed water heater 6 by heating the exhaust gas of the gas turbine 1.
　ガスタービン１の排ガスの加熱による給水加熱器６があると判定された場合(Ｓ４０９でＹｅｓ)、太陽熱による太陽集熱装置７がない状況でのステップ４０３と同様となり、Ｓ４０５に進み、太陽集熱装置７がないために太陽集熱温水のフラグに“０”が設定され、排ガスによる給水加熱器６の温水供給が可能であるので排ガス加熱温水のフラグに“１”が設定される。 If it is determined that there is a feed water heater 6 by heating the exhaust gas of the gas turbine 1 (Yes in S409), the procedure is the same as in Step 403 in the situation where there is no solar heat collecting device 7 by solar heat. Since there is no device 7, the flag of solar heat collecting hot water is set to “0”, and the hot water supply of the feed water heater 6 by exhaust gas is possible, so the flag of exhaust gas heating hot water is set to “1”.
　Ｓ４０９で、ガスタービン１の排ガスの加熱による給水加熱器６がないと判定された場合(Ｓ４０９でＮｏ)、Ｓ４０８へ進み、太陽集熱温水のフラグおよび排ガス加熱温水のフラグともに、それぞれ“０”が設定される。
　このように、太陽集熱温水のフラグおよび排ガス加熱温水のフラグに、“０”または“１”の値が設定されれば、図６の運転条件判定部４００での処理は終了する。
　なお、図６の例では、温水の温度の推定値が設定温度以上であるか否か判断する場合を例示したが、ガスタービン発電装置１００に設けた計測器で計測した温水の温度の計測値を用いて、設定温度以上であるか否か判断してもよい。 If it is determined in S409 that there is no feed water heater 6 by heating the exhaust gas of the gas turbine 1 (No in S409), the process proceeds to S408, and both the solar heat collecting hot water flag and the exhaust gas heating hot water flag are “0”. Is set.
As described above, when the value of “0” or “1” is set in the flag of the solar heat collecting hot water and the flag of the exhaust gas heating hot water, the processing in the operating condition determination unit 400 in FIG. 6 ends.
In the example of FIG. 6, the case where it is determined whether or not the estimated value of the temperature of the hot water is equal to or higher than the set temperature is exemplified. However, the measured value of the temperature of the hot water measured by the measuring instrument provided in the gas turbine power generation device 100. May be used to determine whether the temperature is equal to or higher than the set temperature.
＜制御装置２００の制御部５００での演算機能＞
　次に、図２に示す制御装置２００における制御部５００での演算機能の動作について説明する。
　図７～図１０は、それぞれガスタービン発電装置１００の通常、起動時、停止時、負荷遮断時の各運転状態における運転条件判定部４００の判定結果に応じた制御部５００での機能を示す図である。 <Calculation Function in Control Unit 500 of Control Device 200>
Next, the operation of the calculation function in the control unit 500 in the control device 200 shown in FIG. 2 will be described.
FIGS. 7 to 10 are diagrams illustrating functions of the control unit 500 according to the determination results of the operation condition determination unit 400 in each operation state of the gas turbine power generation apparatus 100 in normal, start-up, stop, and load interruption. It is.
　＜ガスタービン発電装置１００の通常運転時＞
　ガスタービン発電装置１００の通常運転時の図２に示す調整弁１０１～１０９による制御方法を説明する。
　図７は、ガスタービン発電装置１００の通常運転時の調整弁１０１～１０９による制御方法を示した図である。 <During normal operation of the gas turbine power generator 100>
A control method using the regulating valves 101 to 109 shown in FIG. 2 during normal operation of the gas turbine power generator 100 will be described.
FIG. 7 is a diagram showing a control method by the regulating valves 101 to 109 during normal operation of the gas turbine power generator 100.
　通常運転時、太陽集熱温水のフラグおよび排ガス加熱温水のフラグが両方“１”の場合(図７の通常運転時の制御方法の１列目)、図２に示す太陽集熱装置７、給水加熱器６の両方の温水を利用できるため、太陽集熱装置７の集熱管８からの温水のバイパスラインを形成する調整弁１０４と給水加熱器６からの温水のバイパスラインを形成する調調整弁１０５を閉じて、集熱管８からの温水および給水加熱器６からのからの温水が、バイパスラインを経由しないようにする。また、太陽集熱装置７、給水加熱器６の両温水が利用できない場合に備えて設けた通常の水を噴霧をするためのラインを形成する調整弁１０９は閉じておく。 During normal operation, when both the solar heat collecting hot water flag and the exhaust gas heating hot water flag are “1” (first row of the control method during normal operation in FIG. 7), the solar heat collecting device 7 shown in FIG. Since both hot water of the heater 6 can be used, a regulating valve 104 that forms a bypass line of hot water from the heat collecting pipe 8 of the solar heat collector 7 and a regulating valve that forms a bypass line of hot water from the feed water heater 6 105 is closed so that the hot water from the heat collecting pipe 8 and the hot water from the feed water heater 6 do not pass through the bypass line. Moreover, the regulating valve 109 which forms the line for spraying the normal water provided in case the both hot water of the solar heat collecting apparatus 7 and the feed water heater 6 cannot be utilized is closed.
　通常運転時、太陽集熱温水のフラグが“１”で、排ガス加熱温水のフラグが“０”の場合(図７の通常運転時の制御方法の２列目)は、図２に示す太陽集熱装置７の太陽熱による温水のみが利用可能であるため、太陽集熱装置７の集熱管８からのバイパスラインを形成する調整弁１０４を閉じて、集熱管８からの温水がバイパスラインを経由しないようにする。さらに、給水加熱器６の給水側上流の調整弁１０２を閉じて、給水ポンプ５から給水加熱器６のガスタービン１の排ガス側のラインを孤立させる。 During normal operation, when the solar heat collecting hot water flag is “1” and the exhaust gas heating hot water flag is “0” (second row of the control method during normal operation in FIG. 7), the solar collecting hot water shown in FIG. Since only the hot water by the solar heat of the heat device 7 can be used, the regulating valve 104 that forms the bypass line from the heat collecting tube 8 of the solar heat collecting device 7 is closed, and the hot water from the heat collecting tube 8 does not pass through the bypass line. Like that. Further, the regulating valve 102 upstream of the feed water heater 6 on the feed water side is closed, and the exhaust gas side line of the gas turbine 1 of the feed water heater 6 is isolated from the feed water pump 5.
　ここで、給水加熱器６の温水のバイパスラインを形成する調整弁１０５は、太陽集熱装置７の集熱管８の温水の圧力変動や運転中の突発的変動で、太陽熱側の集熱管８の温水が排ガス側のライン(給水加熱器６に続くライン)に逆流してきた場合に備えて開けておく。一方、太陽集熱装置７、給水加熱器６の温水が利用できない場合に備えて設けた通常の水を噴霧するためのラインを形成する調整弁１０９は閉じておく。 Here, the regulating valve 105 forming the hot water bypass line of the feed water heater 6 is a pressure fluctuation of the hot water of the heat collecting pipe 8 of the solar heat collecting apparatus 7 or a sudden fluctuation during operation. Open in case the hot water flows back to the exhaust gas side line (the line following the feed water heater 6). On the other hand, the regulating valve 109 that forms a line for spraying normal water provided in case the hot water of the solar heat collecting device 7 and the feed water heater 6 cannot be used is closed.
　通常運転時、太陽集熱温水のフラグが“０”で、排ガス加熱温水のフラグが“１”の場合(図７の通常運転時の制御方法の３列目)は、図２に示すガスタービン１の排ガスによる給水加熱器６の温水のみが利用可能であるため、給水加熱器６のバイパスラインを形成する調整弁１０５を閉じて、給水加熱器６の温水がバイパスラインを経由しないようにする。さらに、太陽集熱装置７の集熱管８に給水する調整弁１０３を閉じて、給水ポンプ５から太陽熱側の集熱管８に続くラインを孤立させる。 During normal operation, when the flag of the solar heat collecting hot water is “0” and the flag of the exhaust gas heating hot water is “1” (third row of the control method during normal operation in FIG. 7), the gas turbine shown in FIG. Since only the hot water of the feed water heater 6 by the exhaust gas of 1 can be used, the regulating valve 105 forming the bypass line of the feed water heater 6 is closed so that the warm water of the feed water heater 6 does not pass through the bypass line. . Furthermore, the regulating valve 103 that supplies water to the heat collecting pipe 8 of the solar heat collecting apparatus 7 is closed, and the line that continues from the water supply pump 5 to the heat collecting pipe 8 on the solar heat side is isolated.
　太陽集熱装置７の集熱管８の温水のバイパスラインを形成する調整弁１０４は、給水加熱器６の温水の圧力変動や運転中の突発的変動で、ガスタービン１の排ガス側の給水加熱器６の温水が、太陽熱側の集熱管８のラインに逆流してきた場合に備えて開けておく。一方、太陽集熱装置７、給水加熱器６の温水が利用できない場合に備えて設けた通常の水を噴霧するためのラインは、調整弁１０９にて閉じておく。 The regulating valve 104 forming the hot water bypass line of the heat collecting pipe 8 of the solar heat collecting apparatus 7 is a feed water heater on the exhaust gas side of the gas turbine 1 due to pressure fluctuations in the hot water of the feed water heater 6 or sudden fluctuations during operation. 6 is opened in preparation for the case where the warm water 6 flows back to the solar heat collecting tube 8 line. On the other hand, the line for spraying normal water provided in case the hot water of the solar heat collecting device 7 and the feed water heater 6 cannot be used is closed by the regulating valve 109.
　最後の通常運転時の太陽集熱温水のフラグが“０”で、排ガス加熱温水のフラグが“０”の場合(図７の通常運転時の制御方法の４列目)は、図２に示す太陽集熱装置７の集熱管８の温水およびガスタービン１の排ガス側の給水加熱器６の温水が利用できない。そのため、両温水を用いる際に使用する調整弁１０２～１０８を閉じる。そして、給水ポンプ５から吸気冷却室９内の噴霧ノズル１０への給水ラインを形成する調整弁１０１と調整弁１０９を開いて、噴霧ノズル１０から吸気冷却室９内に通常の水噴霧ができるようにする。 FIG. 2 shows the case where the flag of the solar heat collecting hot water during the last normal operation is “0” and the flag of the exhaust gas heating hot water is “0” (fourth row of the control method during normal operation in FIG. 7). The hot water of the heat collecting pipe 8 of the solar heat collecting device 7 and the hot water of the feed water heater 6 on the exhaust gas side of the gas turbine 1 cannot be used. Therefore, the regulating valves 102 to 108 used when both hot waters are used are closed. Then, the adjustment valve 101 and the adjustment valve 109 that form a water supply line from the water supply pump 5 to the spray nozzle 10 in the intake air cooling chamber 9 are opened so that normal water spray can be performed from the spray nozzle 10 into the intake air cooling chamber 9. To.
　なお、吸気冷却室９内の噴霧ノズル１０に温水を供給する調整弁１０６、蒸発器１１に温水を供給する調整弁１０７、インタークーラ１２に温水を供給する調整弁１０８、および、吸気冷却室９内の噴霧ノズル１０に水を供給する調整弁１０９のそれぞれの開度は、各ラインを流れる流体(温水)の圧力、温度、流量をそれぞれ計測し、それぞれの計測値が所望の値になるように制御される。 The adjustment valve 106 for supplying warm water to the spray nozzle 10 in the intake cooling chamber 9, the adjustment valve 107 for supplying warm water to the evaporator 11, the adjustment valve 108 for supplying warm water to the intercooler 12, and the intake cooling chamber 9 Each opening degree of the regulating valve 109 that supplies water to the spray nozzle 10 in the inside measures the pressure, temperature, and flow rate of the fluid (hot water) flowing through each line so that each measured value becomes a desired value. Controlled.
　特に、温水を利用する場合は、温水を減圧沸騰させるための温度条件が重要であるため、減圧沸騰のための設定温度に温水の温度が満たない場合は、太陽集熱装置７の集熱管８の温水のバイパスラインを形成する調整弁１０４や、ガスタービン１の排ガス側の給水加熱器６のバイパスラインを形成する調整弁１０５を開き、それぞれのバイパスラインから流体(温水または水)を排出し、条件を満たさない流体(温水または水)が流れないようにする。温水の温度が減圧沸騰のための設定温度よりも高過ぎる場合も同様である。なお、温水の温度は、ガスタービン発電装置１００に設けた計測器の温度センサで計測する。 In particular, when using warm water, the temperature condition for boiling the warm water under pressure is important. Therefore, when the temperature of the warm water does not satisfy the set temperature for boiling under reduced pressure, the heat collecting tube 8 of the solar heat collecting device 7 is used. Open the regulating valve 104 that forms the bypass line of the hot water and the regulating valve 105 that forms the bypass line of the feed water heater 6 on the exhaust gas side of the gas turbine 1, and discharge the fluid (hot water or water) from each bypass line. Prevent fluid (warm water or water) that does not meet the conditions from flowing. The same applies when the temperature of the hot water is too higher than the set temperature for boiling under reduced pressure. The temperature of the hot water is measured by a temperature sensor of a measuring instrument provided in the gas turbine power generator 100.

Since the hot water of both the device 7 and the feed water heater 6 can be used, the bypass valve for the hot water from the heat collecting pipe 8 of the solar heat collecting device 7 and the bypass line of the hot water from the feed water heater 6 are formed. The adjustment valves 105 to be changed from “open” to “closed”, respectively. The opening adjustment at this time is when the temperature of the hot water reaches the set temperature. If it does not reach the set temperature, it cannot flow to the system (the line following the spray nozzle 10 in the intake air cooling chamber 9, the line following the evaporator 11, the line following the intercooler 12). The hot water is bypassed with the regulating valve 105 open.
　また、給水ポンプ５からの水の供給側の調節弁１０１も、系統に流す温水の温度、圧力、流量の条件に応じて、「閉」から「開」という流量制御を実施する。以下、図８に示す起動時の全ての条件で調整弁１０１は、同様である。
　一方、太陽集熱装置７および／または給水加熱器６による温水が利用できない場合に備えて設けた通常の水噴霧をするためのライン(給水ポンプ５から吸気冷却室９内の噴霧ノズル１０に続くライン)は、調整弁１０９にて閉じておく。 In addition, the control valve 101 on the supply side of water from the water supply pump 5 also performs flow control from “closed” to “open” according to the conditions of the temperature, pressure, and flow rate of the hot water flowing through the system. Hereinafter, the adjustment valve 101 is the same under all the conditions at the time of startup shown in FIG.

　起動時の太陽集熱温水のフラグが“１”で、排ガス加熱温水のフラグが“０”の場合(図８の制御方法の２列目)は、図２に示す太陽熱による集熱管８の温水のみが利用可能であるため、太陽熱による集熱管８の温水のバイパスラインを形成する調整弁１０４を「開」から「閉」とし、徐々に集熱管８の温水がバイパスラインを経由しないようにする。給水加熱器６の上流側の調整弁１０２は閉じておく。
　一方、太陽集熱装置７および／または給水加熱器６による温水が利用できない場合に備えて設けた通常の水噴霧をするためのライン(給水ポンプ５から吸気冷却室９内の噴霧ノズル１０に続くライン)は、調整弁１０９にて閉じておく。 When the solar heat collecting hot water flag at start-up is “1” and the exhaust gas heating hot water flag is “0” (second row of the control method of FIG. 8), the hot water of the heat collecting tube 8 by solar heat shown in FIG. Therefore, the adjustment valve 104 that forms the bypass line of the hot water collecting pipe 8 by solar heat is changed from “open” to “closed” so that the hot water of the heat collecting pipe 8 gradually does not pass through the bypass line. . The regulating valve 102 on the upstream side of the feed water heater 6 is closed.

　一方、太陽集熱装置７および／または給水加熱器６による温水が利用できない場合に備えて設けた通常の水噴霧をするためのライン(給水ポンプ５から吸気冷却室９内の噴霧ノズル１０に続くライン)は、調整弁１０９にて閉じておく。 When the solar heat collecting hot water flag at start-up is “0” and the exhaust gas heating hot water flag is “1” (third row of the control method of FIG. 8), water supply by the exhaust gas of the gas turbine 1 shown in FIG. Since only the hot water of the heater 6 can be used, the regulating valve 105 that forms the bypass line of the hot water of the feed water heater 6 is changed from “open” to “closed” so as not to gradually pass through the bypass line. The regulating valve 103 on the upstream side of the heat collecting tube 8 is closed.
On the other hand, a normal water spray line (prepared from the water supply pump 5 to the spray nozzle 10 in the intake cooling chamber 9) provided in case the hot water by the solar heat collecting device 7 and / or the feed water heater 6 cannot be used. Line) is closed by the regulating valve 109.

The hot water of both the heat collecting pipe 8 and the feed water heater 6 cannot be used. Therefore, the regulating valves 102 to 108 relating to the supply of hot water of both the heat collecting pipe 8 and the feed water heater 6 of the solar heat collecting apparatus 7 are closed, and the regulating valve 101 of the main water supply valve is gradually opened.

　上記構成によれば、温水を噴霧ノズル１０から吸気冷却室９内に噴霧するか、または、温水を蒸発器１１で蒸発させて蒸気として燃焼器４に送り込むか何れかを行うことで、ガスタービン１の入り口の質量流量を増加させる。これにより、ガスタービン発電装置１００の出力の向上を図れる。
　また、燃焼器４に蒸気を送り込むことで、燃焼器４内では安定燃焼範囲の空気となり、燃焼器４の燃焼が安定化する。そのため、燃焼器４の燃焼(排)ガスに含まれるNOxが低減される。また、ガスタービン１の入り口の質量流量を増加し、ガスタービン発電装置１００の出力が向上する。 According to the above configuration, either the hot water is sprayed into the intake cooling chamber 9 from the spray nozzle 10 or the hot water is evaporated by the evaporator 11 and sent to the combustor 4 as steam, whereby the gas turbine Increase the mass flow rate at the inlet of 1. Thereby, the output of the gas turbine power generator 100 can be improved.
Moreover, by sending steam into the combustor 4, the air in the combustor 4 becomes air in a stable combustion range, and the combustion of the combustor 4 is stabilized. Therefore, NOx contained in the combustion (exhaust) gas of the combustor 4 is reduced. In addition, the mass flow rate at the entrance of the gas turbine 1 is increased, and the output of the gas turbine power generator 100 is improved.
　また、圧縮機２の出口から送られるガスタービン１のタービン翼の冷却空気を、インタークーラ１２において温水の蒸発潜熱で再冷却し冷却空気量を低減することで、タービン翼の冷却空気に用いられるエネルギが低減され、発電効率が向上する。
　従って、外気温度が高い期間においても、ガスタービン発電装置１０は定格出力を維持できる。それ以外の期間では、出力向上やあるいは出力一定として燃料を抑制するなどの運用に寄与できる。 Moreover, the cooling air of the turbine blade of the gas turbine 1 sent from the outlet of the compressor 2 is re-cooled by the latent heat of evaporation of hot water in the intercooler 12 to reduce the amount of cooling air, so that it is used for the cooling air of the turbine blade. Energy is reduced and power generation efficiency is improved.
Therefore, the gas turbine power generator 10 can maintain the rated output even during a period when the outside air temperature is high. In other periods, it is possible to contribute to operations such as improving the output or suppressing the fuel with a constant output.
　なお、前記実施形態においては、太陽集熱装置７の集熱管８の温水と給水加熱器６の温水とを、吸気冷却室９内の噴霧ノズル１０と、蒸発器１１と、インタークーラ１２とに用いる場合を例示したが、吸気冷却室９内の噴霧ノズル１０、蒸発器１１、インタークーラ１２のうちの少なくとも何れかに用いるように構成してもよい。また、太陽集熱装置７の集熱管８と給水加熱器６とを備える場合を例示したが、太陽集熱装置７の集熱管８と給水加熱器６との何れかを備えるように構成してもよい。 In the embodiment, the hot water of the heat collecting pipe 8 of the solar heat collecting device 7 and the hot water of the feed water heater 6 are transferred to the spray nozzle 10 in the intake air cooling chamber 9, the evaporator 11, and the intercooler 12. Although the case where it uses is illustrated, you may comprise so that it may be used for at least any one of the spray nozzle 10 in the intake air cooling chamber 9, the evaporator 11, and the intercooler 12. FIG. Moreover, although the case where the heat collecting pipe 8 of the solar heat collecting apparatus 7 and the feed water heater 6 were provided was illustrated, it comprised so that either the heat collecting pipe 8 of the solar heat collecting apparatus 7 and the feed water heater 6 might be provided. Also good.
　また、前記実施形態においては、インタークーラ１２へも、低温沸騰の設定値の範囲内の温水をインタークーラ１２に供給する場合を例示したが、必ずしも低温沸騰の設定値の範囲内の温水をインタークーラ１２に供給しなくともよい。この場合には、低温沸騰の設定値の範囲に温水の温度が達するまで、吸気冷却室９内の噴霧ノズル１０に続く調整弁１０６および蒸発器１１に続く調整弁１０７を閉じ、インタークーラ１２に続く調整弁１０８を開くことになる。 Moreover, in the said embodiment, although the case where the hot water in the range of the setting value of low-temperature boiling was supplied to the intercooler 12 also to the intercooler 12 was illustrated, The cooler 12 may not be supplied. In this case, the adjustment valve 106 following the spray nozzle 10 and the adjustment valve 107 following the evaporator 11 in the intake air cooling chamber 9 are closed until the temperature of the hot water reaches the low-temperature boiling set value range, and the intercooler 12 is turned on.
