Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fuel-fired combined cycle power generation facility having a fuel production facility for producing gas turbine fuel oil from crude oil and / or heavy oil, and a power generation facility for generating electricity by burning the fuel. It relates to the driving method.

[0002]

2. Description of the Related Art Combined cycle power generation, in which oil fuel is burned, generates electricity by rotating a gas turbine using combustion gas obtained by burning fuel gas, and recovers exhaust heat from high-temperature exhaust gas from the gas turbine. To generate steam,
The steam turbine is turned to generate electric power, and a thermal efficiency of about 49% in terms of a higher calorific value is achieved, so that energy can be effectively used. Regarding this combined cycle power generation, Japanese Patent Application Laid-Open No. Hei 9-189206 discloses that steam extracted from a steam turbine of a power generation facility is used as a heat source when raising the temperature of crude oil of a fuel production facility to a distillation temperature. Techniques for improving thermal efficiency have been disclosed. That is, in the above-described technology, a fuel production facility that obtains gas turbine fuel by distilling crude oil and a facility that burns the fuel and generates power cooperate to improve the overall thermal efficiency.

[0003]

However, there are the following problems in transferring heat between the two facilities.

(1) In addition to seasonal fluctuations in power demand, large fluctuations in load are required on the power generation equipment side at short time intervals such as day and night or weekly in accordance with social activities.
To cope with this, it is necessary to adjust the number of operating combined cycle power plants and the load. On the other hand, the fuel production facility has a characteristic that the operation cannot quickly follow a short-term load change and a characteristic that a stable operation cannot be continued at a low load. For example, since the distillation column is a gas-liquid contact device having a large number of trays, it takes a long time to settle after changing the conditions. In addition, when the shelf is operated at a low load, the efficiency may be reduced due to leakage of liquid from the shelf, or the operation may be disabled in some cases. Therefore, when the operation output of the power generation equipment fluctuates, the amount of heat supplied from the power generation equipment to the fuel production equipment fluctuates, which causes a problem that stable continuous operation of the fuel production equipment becomes difficult. For this reason, a mechanism that can absorb the imbalance generated due to the transfer of heat is needed.

(2) Heat exchange in a fuel production facility is generally performed with a hydrocarbon fluid which is a process fluid. On the other hand, the fluid handled by the power generation equipment is generally high-purity boiler feedwater or steam. If hydrocarbons on the fuel facility side leak to the power generation facility side, there is a high possibility that the shutdown of the power generation facility, which is obliged to provide a stable supply, will be accompanied by measures to prevent hydrocarbons from leaking to the power generation facility.

(3) Usually, for a plurality of combined cycle power generation facilities, the fuel production facilities are grouped in one line. There are a plurality of devices that can be a heat source in a fuel production facility. Therefore, a mechanism that can distribute the heat recovered from a plurality of devices to a plurality of devices is required.

The present invention has been made under such circumstances, and an object of the present invention is to provide a technique capable of stably continuing the operation of a fuel production facility even when the operation output of a power generation facility fluctuates. It is in.

Another object of the present invention is to provide a technique capable of continuing the operation of the power generation equipment even if hydrocarbons on the fuel production equipment leak into the heat medium.

As a specific operation method, for example, during normal operation, the pressure of the heat medium sent from the power generation equipment is adjusted so that the heat medium becomes a predetermined pressure by monitoring the pressure of the heat medium supplied to the fuel production equipment, During the unsteady operation, the heat medium is supplied from the bypass line to the fuel production facility so that the pressure of the heat medium supplied to the fuel production facility deviates from a predetermined value. The heat supply source is, for example, heating steam of a power generation facility, and the heat receiving side is at least one selected from, for example, a solvent residue oil, a solvent removal oil and a debutanizer reboiler of a fuel production facility. It is. The heating means is, for example, at least one of a waste heat recovery boiler, a boiler capable of generating steam even when the combined cycle power generation equipment is stopped, and a combustion heating heater. The heat supply side and / or the heat reception side are composed of, for example, a plurality of devices.

According to this invention, when the power generation equipment is operating in a steady state, the heat medium that has received the heat generated in the power generation equipment is sent to the fuel production equipment, supplied with heat, and then returned to the power generation equipment. As a result, heat is exchanged as scheduled, and the thermal efficiency of the entire power generation facility can be improved. In addition, during abnormal operation such as suspension of a part or the whole of the power generation equipment, a stable continuous operation of the fuel production equipment can be performed by circulating the heat medium using the bypass line and supplying necessary heat.

Further, the heat medium is an indirect heat medium which does not come into direct contact with the fluid in the power generation equipment, and the pipe line is provided with heat exchange means for supplying the heat of the fluid to the heat medium. Is also good. In this case, even when hydrocarbons are mixed in the heat medium due to an accident or the like, damage can be minimized without stopping the power generation equipment.

A piping line 90 for returning to the water supply system of B (B1, B2) is provided. The case where the number of the power generation facilities B is one is also included in the scope of the rights of the present invention. Heat exchangers 30-1, 30-2 shown in the heat supply means 30,
In 30-3, the heat of the steam is supplied to the solvent-extracted residual oil 31a, the solvent-extracted extracted oil 31b, and the debutanizer reboiler 23a by heat exchange, respectively. Heat supply means 3
In a piping line 90 downstream of 0, a tank 94 for storing condensed water in which steam is condensed and a pump 95 are provided.

The pipe line 90 is connected to a bypass line 91 that branches off from the pipe line 90 and bypasses the power generation equipment B (B1, B2). In this example, the piping line 90

In the bypass line 91, a circulation pump 92, a heating means 93 for giving necessary heat in the fuel production facility A to the heat medium, and a pressure regulating valve 96 are provided, and are configured as the bypass / heating facility 9. As the heating means 93, a boiler, a heater for heating a heat medium such as hot oil by combustion, or the like is used, and both of them may be used.

A steam line (part of the piping line) 87 from the exhaust heat recovery boiler 86 on the power generation facility B1 side and a steam line 8 from the exhaust heat recovery boiler 86 on the power generation facility B2 side
7 are provided with pressure regulating valves 100 and 101, respectively. On the upstream side of these pressure regulating valves 100 and 101,
Upstream pressure controllers 102 and 103 including a detection unit for detecting the pressure of the upstream steam are provided, respectively, and a downstream side is provided between the junction of the steam lines 87 and 87 and the junction of the bypass line 91. Pressure controller 10

The downstream pressure controller 104 detects the pressure of the steam downstream of the pressure regulating valves 100 and 101, in this example, the pressure of the line where the steam lines 87 and 87 join, and opens the pressure regulating valves 100 and 101. It has the role of adjusting the degree. If the pressure adjusting valves 100 and 101 are adjusted only by the pressure controller 104, the steam from the water supply system may be extracted too much, and the output of the steam turbine 81 may not be secured. Therefore, the lower limit of the steam amount is determined. For upstream pressure controller 10
2, 103 are provided. Therefore, the pressure regulating valve 10
Reference numerals 0 and 101 indicate that the opening degree is adjusted by the downstream pressure controller 104 in a state where the lower limit of the amount of steam withdrawn from the water supply system is determined.
Operation units 105 and 106 for calculating the pressure detection values of 02 (103) and 104 are provided.

The steam pressure is detected between the downstream end of the bypass line 91 in the pipe line 90 and the heat supply means 30, and the pressure of the bypass line 91 is adjusted based on the deviation between the detected value and the set pressure value. A pressure controller 107 for adjusting the opening of the valve 96 is provided. It should be noted that flow adjustment valves 108 and 109 are provided on the piping line 90 upstream of the junction with the water supply system.

Further, a leak detector 110 for detecting the concentration of hydrocarbons in the cooling water is provided in the pipe line 90. For example, if hydrocarbons leak into the cooling water by the heat supply means 30 due to an accident or the like, the leakage detector 110 This can be detected by the detector 110. In this case, the leak detector 110
When the detected hydrocarbon concentration exceeds the set value, a leak detection signal is issued, and the power generation equipment B (B1, B2) is disconnected from the fuel production equipment A by a gate valve (not shown). The leak detector 110 is preferably provided in the vicinity of the outlet side of the heat supply means 30 in order to perform this separation as soon as possible.

Next, the operation of the above embodiment will be described. First, at the time of steady operation, that is, when the power generation equipment B (B1, B2) is operated at a steady output, the feedwater heated by the feedwater heater 84 is sent to the exhaust heat recovery boiler 86, from which a part of the steam is removed. Heat exchange means 30-1 to 30-3 which are bleed from the line 87 and are the heat supply means 30 of the fuel production facility A
0-3, and the heat of the steam is transferred to the heat exchange means 30-1 to 30-1.
The oil is supplied to the solvent-removed residual oil 31a, the solvent-removed extracted oil 31b, and the debutanizer reboiler 23a through 30-3, respectively. At this time, the steam pressure in the steam line 87 is, for example, 2
8 kg / cm 2, the pressure regulating valve 96 of the bypass line 91 is fully closed, and all steam sent to the heat supply means 30 is from the power generation equipment B (B1, B2).

When the power generation equipment B shifts to the unsteady operation, for example, when one of the power generation equipments B2 is stopped, the pressure of the steam sent to the heat supply means 30 decreases. Pressure regulating valve 10
Try to open 0,101. Note that the pressure regulating valves 100, 1
A check valve (not shown) is provided upstream of 01.
The check valve prevents steam from flowing back to the power generation facility B2. Since steam is not sent even when the pressure regulating valve 101 is opened, the opening degree of the pressure regulating valve 100 is increased depending on the supply of steam on the power generation equipment B1 side, and the amount of steam withdrawn from the exhaust heat recovery boiler 86 is reduced. More. However, if the withdrawal amount is too large, the pressure will drop too much, and if it is left as it is, the power output by the steam turbine 81 will drop. For example, when the pressure drops to 25 kg / cm 2, the pressure is further increased by the action of the upstream pressure controller 102. Pressure control valve 10 so that
The opening of 0 is adjusted. Then, since the amount of steam to the heat supply means 30 decreases, the pressure controller 107 opens the pressure regulating valve 96 of the bypass line 91.
The condensate condensed out of the heat supply means 30 is supplied to pumps 95 and 92
Thereby, the steam is sent to the heating means 93 of the bypass line 91, for example, a boiler, and this steam is combined with the steam from the power generation equipment B1 and supplied to the heat supply means 30, that is, the shortage of the steam from the power generation equipment B1 is reduced. Bypass line 91
And the heat supply capacity of the heat supply means 30 is secured. When extracting steam from the power generation equipment B (B1, B2), the steam may be extracted from the steam turbine 81. When the amount of extracted steam is reduced, the steam may be extracted from the high-pressure portion in the power generation facility B.

According to the above-described embodiment, the fuel production facility A is heated by the heat from the steam cycle including the steam turbine of the oil-fired combined cycle power generation facility B, and the fuel used in the fuel production facility A is saved. can do. As a result, the thermal efficiency of the entire combined cycle power generation facility can be improved.

Further, a bypass line 91 provided with a heating means 93 is provided, and the pressure of the steam sent from the bypass line 91 is controlled in accordance with the operation state of the power generation equipment B to heat the fuel production equipment A. Therefore, even during an unsteady operation, for example, when the operation output of at least one of the power generation facilities B1 and B2 is reduced or at least one of them is stopped, a shortage of the steam from the power generation facility B is secured by the steam from the bypass line 91. Therefore, the operation of the fuel production facility A can be stably continued.

In controlling the amount of steam from the power generation equipment B and the bypass line 91, the flow rate control valve may be adjusted using a flow rate controller instead of the pressure controller. In addition, heat may be supplied to one or two of not all of the solvent-removed residual oil 31a, the solvent-removed extracted oil 31b, and the debutanizer reboiler 23a.

FIG. 5 is a view showing a second embodiment of the present invention. As a heat medium for supplying the heat from the power generation equipment B to the fuel production equipment A, steam extracted from the exhaust heat recovery boiler 86 is used. Uses an indirect heat medium that does not directly conflict.
That is, in this example, a steam converter 88 serving as a heat exchange section is provided in the middle of a piping line 90 that circulates the indirect heat medium. The steam converter 88 converts steam from the exhaust heat recovery boiler 86 when viewed from the power generation facility B side. It is provided in a steam line 87 to be extracted. The outlet side of the steam converter 88 on the power generation facility B side is connected to a water supply system, and the condensed water obtained by the steam converter 88 returns to the water supply system.

On the other hand, the indirect heat medium is feed water and steam, and the power generation equipment B (the steam converter 88 is included in the power generation equipment) from the piping line 90 which is the flow path of the indirect heat medium, as in the previous embodiment. , A bypass line 91 is provided. The steam line 87 on the power generation equipment B side is separated from the flow path of the indirect heat medium, and the condensate of the steam flowing there returns to the water supply system of the power generation equipment B. Therefore, the pressure adjustment used in the previous embodiment is performed. No pressure controller 102 is provided to control the lower limit of the pressure upstream of the valves 100, 101.

In this embodiment, the power generation equipment B (B1,
When B2) is in steady operation, the steam line 87
The heat of the steam extracted from is supplied to the indirect heat medium via the steam converter 88, and the feedwater as the indirect heat medium is sent to the heat supply means 30 of the fuel production facility A as steam. When the operation output of the power generation equipment B (B1, B2) becomes low, the heat is exhausted through the pressure regulating valve 100 so that the pressure of the steam sent to the heat supply means 30 becomes a predetermined value by the operation of the pressure controller 104. The amount of steam withdrawn from the recovery boiler 86 is controlled. And, for example, one power generation facility B
2 stops, the amount of heat exchange in the steam converter 88 decreases, and it becomes impossible to catch up with only the steam from the one power generation facility B1.
07, it is detected that the steam pressure has become lower than the set value, and the pressure regulating valve 9 is operated in accordance with the deviation between the set value and the detected value.
6 is opened and steam is sent from the bypass line 91 to secure the heat supply amount to the fuel production equipment A.

In the embodiment shown in FIG. 5, since the bypass line 91 is used, the operation of the fuel production facility A can be stabilized even when the operation output of the power generation facility B is reduced, as in the first embodiment. Can continue. And heat exchange means 30
Since the pressure on the heat source side is high, hydrocarbons on the heat source side may be mixed into the heat medium (pure water) due to an accident or the like. Power generation facility B even if hydrocarbons leak
Since the water does not enter the water supply, the operation of the power generation facility B can be continued by shutting off only the leak source.

In the above, the water supply to the heating means 93 of the bypass line 91 may be performed from another system other than the pump 92, or the steam may be supplied from the heating means 93 to the fuel production facility A.
Instead of supplying steam from other power generation facilities in operation, for example, steam from a power generation facility that performs power generation using steam from a boiler using heavy oil obtained at fuel production facility A, The shortage of steam from the power generation equipment B (B1, B2) may be secured.

Here, when a specific trial calculation was performed using the present invention, the amount of steam supplied from the power generation equipment was 29.0 t.
/ H, which contributes to the reduction of 3,000 kg / h of fuel in the fuel facility. As a result, an effect corresponding to an increase in the amount of power of 104,000 MWh per year can be expected as a utilization rate of 70%.
