Description

TECHNICAL FIELD [0001] The present invention relates to a gas processing apparatus,

The present invention relates to a gas processing apparatus and method, and more particularly, to a gas processing apparatus and method capable of effectively purifying a gas before detecting components of the gas.

The blast furnace is a high-temperature, high-pressure reaction to produce molten iron. The process of producing molten iron in a blast furnace is referred to as a blast furnace process, for example, as follows. In the bottom of the blast furnace, coke and pulverized coal are burned with hot air to generate reducing gas. Then, the reducing gas is moved to the upper part of the blast furnace and the iron ore is reduced and melted by the reducing gas to produce molten iron. In this process, iron ore and reducing gas must sufficiently contact with each other in order to increase the process efficiency. In order to make iron ore and reducing gas sufficiently contact with each other, the charging condition of the blast furnace should be sound.

The fact that the charging condition of the blast furnace water is sound means that the air gap is well secured in the filling layer of the blast furnace charge so that the flow of the reducing gas and the molten iron can be smoothly performed. If the packed bed condition is not good, the reducing gas drifts, and the reducing gas escapes the furnace without being sufficiently used for the reduction of iron ore. In this case, the ratio of the reducing gas in the blast furnace gas discharged from the blast furnace is high.

Therefore, by detecting the component of the blast furnace gas and knowing the ratio of the reducing gas in the blast furnace gas, it is possible to determine the gas utilization ratio and the charging state of the blast furnace charge based on the reduction gas ratio, and the process efficiency can be evaluated. For this reason, it is the component detection value of the blast furnace gas which is necessarily used for the evaluation of the process efficiency in the blast furnace process.

On the other hand, during the production of molten iron in the blast furnace, iron ore and coke are differentiated in the blast furnace, and a large amount of dust is generated. A large amount of dust is mixed with the blast furnace gas and discharged together with the blast furnace gas through the blast furnace. Since the blast furnace gas containing a large amount of dust is difficult to detect, the blast furnace gas must be cleaned before the blast furnace gas component is detected. Conventionally, as a purifier, a cyclone and various filters were installed in a tube for collecting blast furnace gas, and the blast furnace gas was cleaned by using the blast furnace gas and the blast furnace gas was used to detect the component of the blast furnace gas using an infrared component analyzer .

However, the conventional blast furnace gas purifying apparatus has various problems. First, if the dust is abruptly generated suddenly, there is a problem that the cyclone and the filter can not function properly. In addition, since the worker must always check the state of the filter, there is a problem that workload of the worker is increased. Further, if the operator does not replace or maintain the filter at an appropriate time, the state of the filter can not be maintained satisfactorily so that the dust is blocked by the air gap of the filter, thereby deteriorating the performance of the filter and insufficient purified blast furnace gas.

If the blast furnace gas is not sufficiently purified by these problems, not only the infrared component analyzer is damaged by the dust but also noise is generated in the result of detection of the component, thereby adversely affecting the blast furnace process.

Techniques as a background of the present invention are listed in the following patent documents.

A method of treating a gas according to an embodiment of the present invention includes the steps of: preparing a treated material in a treated material container; Introducing gas from the vessel; Removing impurities by passing the gas through a gas purifier containing water; And supplying the gas via the gas purifier to the detector.

The step of passing the gas through is a step of passing the gas directly through the water; And collecting the gas escaping the water.

The blast furnace gas is directly passed through the gas purifier To remove the impurities contained in the blast furnace gas, and to supply the component analyzer with clean blast furnace gas from which the impurities have been removed. At this time, even if the amount of the impurities contained in the blast furnace gas increases sharply, the water contained in the gas purifier sufficiently covers the purification quality of the blast furnace gas and can always keep the quality of the blast furnace gas clean. That is, the blast furnace gas can be effectively refined before the component of the blast furnace gas is detected, and the refining efficiency of the blast furnace gas can be optimized.

That is, the gas purifier can purify the blast furnace gas while replenishing water permanently from the blast furnace gas. This makes it possible to simplify the installation structure and the operating method of the gas purifier and to reduce the burden on the operator.

However, the present invention is not limited to the embodiments described below, but may be embodied in various forms. It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS The drawings may be exaggerated for purposes of describing embodiments of the present invention, wherein like reference numerals refer to like elements throughout.

The present invention relates to a gas treatment apparatus and method capable of effectively purifying a gas after collecting a gas from a vessel during a treatment process using the vessel and detecting the components thereof, It provides technical features that can optimize efficiency and simplify installation structure and operation method for gas purification.

FIG. 1 is a schematic view of a vessel and a gas processing apparatus according to an embodiment of the present invention, FIG. 2 is a partial view showing a cylinder and a collecting tube of a gas processing apparatus according to an embodiment of the present invention, Fig. 6 is a partial view showing the remainder of the gas processing apparatus except the cylinder according to the embodiment. Fig. 4 (a) and 4 (b) are partial views of a gas purifier according to an embodiment and modifications of the present invention.

1 to 4, the gas processing apparatus 200 according to the embodiment of the present invention can penetrate a processed substance container (hereinafter referred to as "container 10"), A cylinder 210 in which an opening 211 which can be exposed is formed is connected to the cylinder 210 so that the gas g can be introduced from the vessel 10 and the gas w a detector 250 connected to the gas purifier 230, a gas purifier 230 connected to the gas purifier 230, a gas purifier 230 connected to the gas purifier 230, a gas purifier 230 connected to the gas purifier 230, And a gas reservoir 240 formed to allow the gas to flow in and out, and to connect between the gas purifier 230 and the detector 250.

Referring to Fig. 1, a container 10 to which an embodiment of the present invention is applied will be described.

The vessel 10 may include a blast furnace. The main body 11 of the vessel 10 includes a cylindrical scoop having a space formed therein and a refractory wall built inside the iron pour. The main body 11 is formed with a bow inlet. The main body 11 has a plurality of tuyeres 12 radially formed in a lower portion thereof. A ring-shaped hot air supply unit 13 is mounted to connect the plurality of tuyeres 12 from the lower part of the main body 11. [ And a plurality of outlets 14 are formed through the lower portion of the main body 11 so as to be spaced apart from the plurality of tuyeres 12. The main body 11 has a bath surface height measuring device 15 formed thereunder. The bath surface height measuring device 15 measures the height of the bath surface of the molten iron stored in the lower portion of the main body 11 by using the stress or electric current which is transmitted by the iron fat. The vessel 10 may include various treatment vessels in addition to the blast furnace.

The treatment process using the vessel 10, such as the blast furnace process, will be briefly described below.

The processing object is charged into the main body 11. [ The treated material may be a blast furnace charge including iron ore, sinter ore and coke. Hot air and pulverized coal are blown into the lower part of the main body 11 through the tuyere 12, and coke and pulverized coal are burned by hot air to generate a reducing gas. The reducing gas is moved to the upper part of the main body 11 and brought into contact with the iron ores and the sintered ores, and the iron ores and the sintered ores are reduced and melted to produce the molten iron. The charcoal is stored in the lower portion of the main body 11. When a predetermined time has elapsed, the charcoal is opened to open the charcoal.

The blast furnace gas is discharged through the furnace of the main body 11 during the blast furnace process. By detecting the component of the blast furnace gas and obtaining the gas utilization rate of the blast furnace gas (see the following relational expression 1), the charging state of the blast furnace charge can be diagnosed and the process efficiency can be evaluated.

Relation 1) Gas utilization rate = (CO ₂ content) / {(CO content) + (CO ₂ content)}

As the gas utilization ratio approaches 1, the reduction reaction by the reducing gas is smooth and the charging state of the blast furnace charge can be sound.

Therefore, during the blast furnace process, it is essential to detect the component of the blast furnace gas. However, the blast furnace gas contains a large amount of impurities such as dust, and blast furnace gas containing impurities can not accurately perform the component detection. For example, when infrared rays are used to detect the component of the blast furnace gas, the impurity acts as noise. After removing the impurities to clean the blast furnace gas, the components must be detected to obtain accurate and stable results. On the other hand, the reducing gas includes carbon monoxide and hydrogen, among which hydrogen is used as a reducing gas to produce water (H ₂ O). The water is vaporized by the high temperature in the main body 11 and is necessarily contained in the blast furnace gas (hereinafter referred to as "gas g") in a saturated vapor state. In particular, in the case of the blast furnace, 5 to 10% of the reducing gas is hydrogen, so that the saturated vapor v can be smoothly supplied. In this case, the gas purifier 230 does not need to receive the water w from the outside.

The gas processing apparatus 200 according to the embodiment of the present invention can purify the gas g by utilizing the saturated vapor v contained in the gas g collected from the vessel 10. At this time, purifying the gas (g) means removing the impurity from the gas (g).

Next, each component of the gas processing apparatus 200 according to the embodiment of the present invention will be described in detail.

Referring to Figs. 1 and 2, a cylinder 210 penetrates a container 10 and is mounted inside the container 10. Fig. At this time, the tubular body 210 can be detachably mounted inside the container 10 through the upper portion of the container 10 in the radial direction r. A plurality of openings 211 may be formed in the cylinder 210 so that the gas g can be introduced from a plurality of positions of the vessel 10 in the radial direction r. A plurality of openings 211 are formed at predetermined positions on the outer circumferential surface of the cylindrical body 910 so as to be located inside the vessel 10 when the cylindrical body 210 is mounted inside the vessel 10. [ That is, a plurality of openings 211 that can be exposed to the inside of the container 10 may be formed in the cylinder 210. The openings 211 may be spaced apart from each other in the radial direction r on the outer circumferential surface of the cylinder 210. Through openings 211, gas g can be introduced at a plurality of locations in the radial direction r of the vessel 10. The tubular body 210 may be in the shape of a pipe having a circular cross section, but is not particularly limited thereto. The cylindrical body 210 protects the sampling pipe 220 to be described later and positions the inlet of each sampling pipe 220 at a plurality of positions in the radial direction r of the container 10, In the radial direction (r). The inflow of the gas g from the vessel 10 into the opening 211 is naturally carried out from the high pressure vessel 10 to the low pressure sampling vessel 220 by the pressure difference between the vessel 10 and the sampling tube 220 .

The sampling pipe 220 connects the cylinder 210 and the gas purifier 230. A plurality of sampling pipes 220 may be provided corresponding to the number of openings 211, and may be provided in the same number as the openings 211, for example. Six openings 211 and six sampling tubes 220 are illustrated in the embodiment. Of course, the number of these can vary. One end of each sampling pipe 220 is connected to each of the openings 211 through the tubular body 210 while the other end of the sampling pipe 220 extends outside the tubular body 210 and is connected to the gas purifier 230. At this time, a plurality of gas purifiers 230 may be provided according to the number of the sampling pipes 220, and may be provided in the same number as the sampling pipe 220.

The gas (g) in the vessel (g) can be introduced into the sampling tube (220) through the opening (211). At this time, gas (g) for each position of the vessel 10 is introduced into the inlet side of each sampling tube 220 in the radial direction r, and is passed through the inside of each sampling tube 220, And then supplied to each connected gas purifier 230. A sampling pipe control valve 221 may be mounted on the outlet side of each sampling pipe 220. The sampling pipe control valve 221 may be connected to a controller 270 to be described later so that opening and closing thereof can be controlled.

On the other hand, the length of the sampling pipe 220 can be determined so as to keep the inside thereof at a temperature higher than the dew point. Here, the saturation temperature or the condensation temperature may be used instead of the dew point. Any one of them may be used as long as it can define a temperature higher than the temperature at which the condensation of the saturated vapor (v) mixed in the gas (g) passing through the sampling pipe 220 is started using the saturation temperature or the condensation temperature . The temperature of the gas g in the sampling tube 220 is lowered as the length of the sampling tube 220 is longer and the temperature of the inlet gas of the sampling tube 220 and the temperature of the gas g and a heat transfer coefficient between the sampling pipe 220 and the sampling pipe 220 so that the internal temperature of the sampling pipe 220 is higher than the dew point at the outlet of the sampling pipe 220. If the saturated vapor (v) remains in the gaseous state in the sampling pipe (220), impurities are prevented from adhering to the inner wall of the sampling pipe (220), and smooth gaseous flow can be ensured. At this time, if the length of the sampling pipe 220 is determined so that the temperature inside the sampling pipe 220 approaches the dew point at a temperature higher than the dew point at the outlet side of the sampling pipe 220 contacting the gas purifier 230, g may flow into the gas purifier 230 and then rapidly cool down below the dew point so that the saturated vapor v may be phase-changed to condensed water.

(Not shown) may be provided in the sampling pipe 220 so as to keep the inside of the sampling pipe 220 at a temperature higher than the dew point. At this time, the heat keeping means may be various, such as a heat insulating material, a heat wire, a thermoelectric element, and the like, and there is no particular limitation thereon. The gas g introduced into the detection tube 220 can be kept at a temperature higher than the dew point by using the warming means. Thus, no condensation water is generated in the detection tube 220, and adhesion of impurities can be prevented. On the other hand, the sampling pipe 220 itself may include an insulating material.

The number of the gas purifiers 230 is the same as the number of the sampling pipes 220. Each of the gas purifiers 230 is connected to the cylinder 210 so that the gas g can be introduced from the vessel 10 through each of the collecting tubes 220, (g) can be purified.

Referring to Figure 3, the gas purifier 230 may include a gas inlet 233a positioned to immerse the end in water w and a gas outlet 234a located remotely from the water w. When the gas g is sprayed to the water w through the gas inlet 233a and the water w and the gas g actively contact with each other by the bubbling of the gas g, Impurities are collected in the water (w) and removed. The gas (g) from which the impurities have been removed passes through the water (w) after a predetermined time, escapes to the water surface, and can be discharged to the gas outlet 234a. At this time, the saturated steam (v) contained in the gas (g) may become condensed water and remain in the water (w).

The gas purifier 230 is formed inside a tablet vessel or a purifier vessel in which water is contained and is connected to the tubular body 210 through one end of the sampling tube 220 and the other end is submerged in the water w And may include an inlet tube 233 through which the gas g passes, a discharge tube 234 spaced from the water w and passing through the tablet vessel. The other end of the inflow pipe 233 may be the gas inlet 233a and one end of the both ends of the discharge pipe 234 located inside the tablet vessel may be the gas outlet 234a.

The tablet vessel is connected to the upper portion of the first tablet vessel 231 and the first tablet vessel 231 in which the water w is contained and the other end of the inlet tube 233 is located, And a second tablet vessel 232 through which the fluid is passed. The first purification vessel 231 serves as a water tank and the gas g in the first purification vessel 231 can be purified and bubbled into the water w. The second tablet vessel 232 serves to collect the gas g that escapes the water w.

The inflow pipe 233 extends vertically across the second tablet vessel 232, and the other end can be immersed in the water w. The inlet pipe 233 serves to guide the gas g into the water w and serves to cool the temperature of the gas g to below the dew point. The saturated vapor (v) can be phase-changed into condensed water in the inlet pipe (233). For this purpose, the length of the inflow pipe 233 can be determined so as to cool the inside of the inflow pipe 233 to below the dew point. At this time, the length of the inflow pipe 233 is set such that at least one of the air cooling length D1 located on the upper side of the water w and the water cooling length D2 immersed in the water w as shown in FIG. Can be determined differently. The air cooling length D1 may be set to be longer than the water cooling length D2, or may be determined to be opposite thereto, and of course, the two lengths may be set to be the same. This can be determined according to the temperature of the gas (g) at the top of the inlet pipe (233) and the degree of cooling of the gas (g) at each part of the inlet pipe (233).

On the other hand, as a modified example, the shape of the inflow pipe 233 may be a curved shape as shown in Fig. 4 (b). When the pressure of the gas g passing through the inflow pipe 233 is high enough to avoid impurity adhesion by the condensed water, the shape of the inflow pipe 233 may be a tubular shape in order to improve the cooling efficiency. 4 (a) is referred to as an intuitive type. In this case, the drainage of the condensed water is easy and the inflow of the gas g can be smooth.

On the other hand, the inlet pipe 233 may be provided with cooling means (not shown). The cooling means may be a cooling fin, a heat pump, a thermoelectric element, or the like, and the kind thereof is not limited.

The gas purifier 230 may include a water level sensor 236 mounted on one side of the first tablet vessel 231 and a drain port 237 connected to the other side of the first tablet vessel 231. The level of the water w is increased by the level sensor 236 so that the proper level is maintained in the first purification vessel 231. In this case, Detects the water level, opens and closes the drain valve (not shown) of the drain port 237, and adjusts the water level.

The other end of the discharge pipe 234 may extend outside the tablet vessel and may be connected to the gas reservoir 240. The discharge pipe 234 may be fitted with a discharge valve 235.

The gas purifier 230 includes a dispersing member (not shown) disposed in the first purification vessel 231 so as to be submerged in the water w, a bubbling gas g in the water w, (Not shown) that is configured to vibrate or rotate the substrate.

For example, the dispersion member may be a dispersion plate having a plurality of through holes, or an impeller having a plurality of propellers. If the dispersion member is a dispersion plate, the dispersion plate is disposed in a predetermined direction in the bubbling region of the gas (g), and can be supported by the flow means. At this time, the flow means may be a spring that connects the dispersion plate to the first tablet vessel 231 or the inflow tube 233, or a buoy that is disposed on the water surface of the water w and is connected to the dispersion plate. The gas (g) passes through the dispersion plate during bubbling and can be dispersed in a small size. If the dispersing element is an impeller, the flow means may be a bearing. At this time, a bearing is mounted around the inflow pipe 233, and the impeller can be mounted on the bearing. The impeller can be rotated by the bubbling and the bubble of the gas g can be crushed to a small size. The dispersing member and the flow means may have a variety of structures, and may be of various structures satisfying small crushing of the bubble of gas (g).

The gas purifier 230 having the above-described structure has a simpler installation structure than the water treatment apparatus such as a bishop or a wet scrubber and has an advantage in that the operation method is easy. Particularly, since the gas purifier 230 can receive the condensed water generated from the saturated steam v contained in the gas g to permanently replenish the water while purifying the gas g, There is no need for a required installation space, and there is an advantage that it occupies less installation space. Further, even if the water is not periodically replaced, the water w is always added by the condensed water, and the water w is purified by itself, and the purification efficiency of the water w can be kept high. At this time, the water level of the water w is adjusted by the drain port 237. On the other hand, since the above-described water treatment apparatus is required to continuously supply water, a corresponding installation space is needed.

The plurality of gas reservoirs 240 may correspond to the number of the gas purifiers 230 and may be the same as the number of the gas purifiers 230. That is, a plurality of gas purifiers 230 and a plurality of gas reservoirs 240 are formed corresponding to the number of openings 211.

The gas reservoir 240 may be formed such that the gas g can be stored in and out. The gas reservoir 240 temporarily stores the gas and supplies the gas to the detector 250. The structure of the gas reservoir 240 for this purpose may vary.

The gas reservoir 240 includes a gas chamber 241 having an internal space therein, a cylinder 242 movably installed inside the gas chamber 241, a head portion of the cylinder 242 and a gas chamber 241, A storage member 243 which is disposed between the gas purifier 230 and the other end of the discharge pipe 234 of the gas purifier 230 through which the gas g expands and shrinks according to the degree of storage of the gas g, A cylinder actuator 244 which is mounted on the gas chamber 241 and moves the cylinder 242 to forcibly regulate the expansion and contraction of the storage member 243 so that one end of the cylinder 244 passes through the gas chamber 241, And a supply valve 246 mounted to the supply pipe 245. The supply pipe 245 is connected to the supply pipe 245, The storage member 243 may be a diaphragm or an elastic membrane.

The gas reservoir 240 connects the gas purifier 230 and the detector 250 and stores the gas g in the storage member 243 and supplies the gas g to the detector 250, . When the discharge valve 234 mounted on the discharge pipe 234 of the gas purifier 230 is opened, the purified gas g flows into the storage member 243, and the cylinder actuator 244 moves to the head of the cylinder 242 Thereby causing expansion of the storage member 243. At this time, the supply valve 246 mounted to the supply pipe 245 may be in a cut-off state. Thereafter, at a predetermined time, when the supply valve 246 is opened, the gas g is supplied to the detector 250 through the supply pipe 245, at which time the discharge valve 234 is opened or blocked, The cylinder actuator 244 can maintain the retracted state of the head of the cylinder 242 or advance the head of the cylinder 242 to induce the retraction of the storage member 243. It is possible to simultaneously sample the gases collected at the plurality of positions by the gas reservoir 240 and store them.

On the other hand, the uncorrelated 247 can be mounted on the downstream side of the supply valve 246 through the supply pipe 245, and the emergency valve 248 can be mounted on the uncorrected 247. At the end of the uncorrelated portion 247, a combustor 260 is mounted. If the blast furnace process is terminated or if necessary the gas g must be discharged to the outside air, the emergency valve 248 is opened to introduce the gas g into the noncorrosion 247, and the combustor 260 is operated, And the gas (g) discharged to the outside is burned and removed. The cylinder actuator 244, the supply valve 245, the compensation valve 248 and the combustor 260 can be controlled by a controller 270 described later.

A plurality of gas reservoirs 240 are connected to the detector 250 and a detector 250 is connected to each gas purifier 230 through each gas reservoir 240. The detector 250 may include an infrared component analyzer to detect the component of the gas. The infrared component analyzer can detect the components of the supplied gas (g), and can analyze the component content, the volume fraction, the mass fraction or the mole fraction of each component in various ways. The value detected in the infrared component analyzer can be used to calculate the gas utilization rate.

The gas processing apparatus 200 according to an embodiment of the present invention may include a plurality of gas reservoirs 240 so that the plurality of gas reservoirs 240 can alternately supply the gas g to one detector 250. [ And a controller 270 that controls the operation of the valves provided. The controller 270 may control each supply valve 246 to operate alternately. Accordingly, the gas can be alternately supplied from the plurality of gas reservoirs 240 to one detector 250 to detect the component. That is, it is possible to detect all the gas components at the plurality of positions sampled by each sampling pipe 220 with one detector 250.

Hereinafter, a gas treatment method according to an embodiment of the present invention will be described. At this time, the contents overlapping with the gas processing apparatus described above will be omitted or briefly explained.

The gas treating method according to the embodiment of the present invention is characterized in that the gas treating method according to the embodiment of the present invention includes a process of preparing a treated substance in a treated substance container, a process of introducing gas from the container, a process of removing impurities via gas to a gas- And supplying the gas to the detector.

First, a treated material is placed in a treated material container, for example, a container 10. For example, blast furnace blast furnace charge is charged. That is, the vessel 10 includes a blast furnace for producing molten iron, and the treatment may include blast furnace charge.

Thereafter, hot air is injected into the lower part of the vessel 10 to treat the treated water. Hot air and pulverized coal are injected into the lower part of the vessel 10 through the tuyere 12, for example. The coke and the pulverized coal are burned by the hot wind to generate the reducing gas and the reducing gas moves to the upper part of the vessel 10 to contact the iron ores and the sintered ores to reduce and melt them to produce molten iron.

During the processing of the treated material, gas (g) is discharged through the openings of the container 10. The gas (g) is discharged from the container 10 by using the cylinder 210 mounted on the top of the container 10 . At this time, the gas (g) includes the saturated vapor (v), and impurities are mixed therein.

While the gas g is introduced (also referred to as "picking"), the temperature of the gas g is kept higher than the dew point. This is to prevent condensation water from being generated inside the sampling pipe 220 connecting the tubular body 210 and the gas purifier 230.

Thereafter, impurities are removed through gas (g) to the gas purifier 230 containing water (w). At this time, the gas (g) is directly passed through the water, and the gas (g) escaping the water (w) is collected. At this time, the impurities can be completely collected in the water (w) and removed.

The temperature of the gas g is cooled to below the dew point in the gas purifier 230 while the gas g is passed through the gas purifier 230 and the condensed water separated from the cooled gas is introduced into the gas purifier 230, . At this time, the water level of the water w may be increased. At this time, the water level of the water w can be controlled by using the water level sensor 236 and the drain port 237. Accordingly, since the water w is continuously purified using the condensed water, the purification efficiency of the gas purifier 230 can be maintained at a high efficiency, and the operation of the gas purifier 230 can be remarkably stable and simplified.

Thereafter, the gas passed through the gas purifier 230 is supplied to the detector 250. The gas passed through the gas purifier 230 is temporarily stored in the gas reservoir 240, and then supplied to the detector 250. Particularly, when introducing gas at plural positions in the radial direction (r) of the container (10) when introducing the gas (g), the process of passing the gas (g) The gas stored in the gas reservoir 240 may be temporarily stored in the gas purifier 230. When the gas is supplied to the detector 250, The plurality of gas purifiers 230 and the gas reservoir 240 can alternately and stably supply the gas at the plurality of positions to the single detector 250. In addition,

Then, the component of the supplied gas is detected. The detection result can be detected for each of a plurality of positions in the radial direction (r). Accordingly, the gas utilization rate can be calculated for each location subsequently, and it is possible to judge whether the charging state of the blast furnace charge is sound or not and to control the charging mode based on the calculated gas utilization rate. That is, based on the gas utilization rate, it is determined whether the charging state of the blast furnace charge is sound at each position in the radial direction (r), and the blast furnace process is performed so as to exhibit the optimum process efficiency at each position. Water supply distribution adjustment plan can be obtained.
