[0002]

2. Description of the Related Art A conventional power generating apparatus used for an underwater vehicle such as a submarine will be described with reference to FIG.

The steam thermometer 19 is electrically connected to the oxidant flow control valve 13. Between the other end of the tube 11a of the reaction vessel 11 and the water supply pump 15,
A water flow meter 20 is provided. A bypass line 21 having a water flow control valve 16 is provided between the water flow meter 20 and the buffer tank 14. The water flow meter 20 is electrically connected to the water flow control valve 16. In the figure, 23 is a speed reducer, and 24 is a propeller.

[0005] In such a power generation device, the reaction vessel 11 is supplied from the oxidant tank 12 through the oxidant flow control valve 13.
When a predetermined amount of the oxidizing agent 10b is supplied into the reaction vessel 11 and the water supply pump 15 is operated to supply the water 10c in the buffer tank 14 into the tube 11a of the reaction vessel 11, the reaction between the metal fuel 10a and the oxidizing agent 10b The water 10c is heated by the heat generated as a result to become steam 10d, and this steam 10d drives the turbine 17 to rotate the propeller 24 through the speed reducer 23, and is then cooled by the condenser 18.

And an oxygen gas generator 120, wherein hydrogen 3 and oxygen 4 are generated so as to have a substantially equivalent ratio, and are reacted in the combustor 130 to generate steam 6.

[Formula 1] H ₂ + 1 / 2O ₂ → H ₂ O (HT)

The hydrogen gas generator 110 includes the holding vessel 11
1, a metal container 1 is held in a molten state, and a holding container 1
By injecting water 5 from the injection nozzle 112 into the inside 11, the metal fuel 1 reacts with the water 5 to generate hydrogen 3 and supply it to the system. Holding container 111
Is divided into two parts after the operation is completed, and the heat-resistant container 111c to which the reaction residue adheres and the heat insulating material 111b are separated.
If it is removed from a, the most expensive pressure-resistant container 111a can be reused, so that the running cost can be reduced.

The oxygen gas generator 120 includes the holding vessel 12
1, the oxygen generating agent 2 heated to the melting point by a heater or the like (not shown) is fed into the inside of one end of the pipe main body 122a of the hot pipe 122 by the feed pump 123, and is heated and decomposed by the starting heater 122c. 4 is sent out from the through hole 122aa and the other end side of the pipe main body 122a, and is sent out through the filter 125 while being decelerated by the detour by the splash prevention plate 124.

The reason why the through hole 122aa is formed in the pipe main body 122a of the hot pipe 122 is that, in the process of thermally decomposing the oxygen generating agent 2, the generated oxygen 4 causes the oxygen generating agent 2 being decomposed to be decomposed at the other end. This is to prevent the material from being pushed out from the outside (that is, a "release hole").

When lithium perchlorate is used as the oxygen generating agent 2, the following reaction occurs in the hot pipe 122.

## STR2 ## LiClO ₄ → LiCl + 2O ₂

Lithium perchlorate has a decomposition temperature of 440 ° C.
For this reason, when heated above this temperature, it decomposes and generates oxygen 2 to generate heat up to 800 ° C. or more. Therefore, when the decomposition reaction starts to some extent in the hot pipe 122, the temperature above the decomposition temperature can be maintained without supplying power to the starting heater 122c. Also,
The pipe body 122a of the hot pipe 122 is
2b, the inside of the pipe body 122a can be easily maintained at a temperature equal to or higher than the decomposition temperature, the power consumption of the starting heater 122c can be reduced, and during that time, the restart can be performed sequentially.

Residue 2 after release of oxygen 4 of oxygen generator 2
a (lithium chloride in the case of using lithium perchlorate as the oxygen generating agent 2) flows out of the other end of the pipe body 122 a of the hot pipe 122 in a liquid state (melting point: 608 ° C.) and drops into the holding container 121. I do. At this time, since the melting temperature of the oxygen generating agent 2 is sufficiently different from the decomposition temperature, the oxygen generating agent 2 in the holding container 121 does not cause a decomposition reaction.

The holding container 121 is divided after the operation is completed, and the heat-resistant container 121c and the heat insulating material 121b to which the residue 2a is adhered are removed from the pressure-resistant container 121a, and the heat-resistant container 121c and the heat insulating material 121b are washed with water. The material 2a can be easily removed (the residue 2a is water-soluble), and the heating temperature is about the melting temperature of the oxygen generator 2 (about several hundred degrees). Since it has almost no adverse effect, it can be reused and running costs can be reduced.

In the combustor 130, hydrogen 3 is supplied from a hydrogen nozzle 132a of an injection nozzle 132 to the main body 131, and oxygen 4 is supplied from an oxygen nozzle 132b. Since hydrogen 3 and oxygen 4 are usually at or above the ignition temperature,
As soon as it is supplied into the main body 131, it reacts to generate steam 6. If the temperature of the hydrogen 3 or the oxygen 4 is not sufficient, an ignition device (a heater, a spark plug, a platinum catalyst, etc.) may be provided near the injection nozzle 132 in the main body 131.

When the hydrogen 3 reacts with the oxygen 4, the temperature of the steam 6 may reach several thousand degrees, so that the water temperature is controlled by the steam temperature controller 180 into the cooling water passage 131 a of the main body 131 of the combustor 130. Is supplied while controlling the temperature of the turbine 140 to generate steam 6 having a predetermined temperature that matches the operating conditions of the turbine 140.

[Formula 3] H ₂ O (HT) + H ₂ O (L) → H ₂ O (G)

The steam 6 (H
₂ O (G)) is cooled by the condenser 150 and returned to the water 5 and then sent to the buffer tank 160. The water 5 is stored in the buffer tank 160 in advance, and
The amount of water held in the system differs depending on the output of 0. For example, as shown in FIG. 5, when switching to the high output operation, the water level of the water 5 in the buffer tank 160 is changed to the high output corresponding position based on the measurement result of the water level meter 171 of the water supply amount control device 170. The water supply amount control valve 172 controls the water supply amount control valve 172 to release the water 5 into the system. When the water 5 reaches the corresponding position, the water supply amount control valve 172 controls the supply amount of the water 5 so as to maintain the position.

In a constant output state excluding the start state and the shift state, the supply amount of the water 5 is controlled so that the water level of the buffer tank 160 does not fluctuate. The water 5 in the buffer tank 160 is supplied to two systems, that is, a hydrogen gas generator 110 and a combustor 130.
The measurement result of the cooling water flow meter 182 of the
Is controlled to be a value corresponding to the output of. Specifically, while controlling the cooling water amount control valve 183 so that the measurement result of the cooling water flow meter 182 of the steam temperature control device 180 is constant, the measurement result of the water level meter 171 of the water supply amount control device 170 is determined to be constant. The water supply amount control valve 172 is controlled so as to be as follows. For the delicate temperature adjustment of the steam 6, correction control is performed by the cooling water amount control valve 183 based on the measurement result of the steam thermometer 181. In the water supply system, a configuration as shown in FIG. 7 can be applied.

Therefore, the temperature of the steam 6 (H ₂ O (G)) is adjusted by adjusting the supply amount of the water 5 to the combustor 130 together with the supply amounts of the hydrogen 3 and the oxygen 4 to the combustor 130. Therefore, water vapor 6 (H ₂ O)
(G)) The temperature can be adjusted with high responsiveness.

Here, water 5 (H ₂ O (L)) used for cooling in the combustor 130 is supplied to the cooling water passage 131 of the main body 131.
A is merely circulated to cool high-temperature steam 6 (H ₂ O (HT)) and does not contribute to the reaction. That is, the same amount of water 5 as high-temperature steam 6 (H ₂ O (HT)) generated in the combustor 130 is supplied to the hydrogen gas generator 110.

For example, when aluminum is used as the metal fuel 1, the following reaction occurs in the hydrogen gas generator 110.

[Formula 4] 2 / 3Al + H ₂ O → 1 / 3Al ₂ O ₃ + H ₂

That is, the amount of water 5 used in the hydrogen gas generator 110 depends on the fact that the hydrogen 3 generated in the hydrogen gas generator 110 and the oxygen 4 generated in the oxygen gas generator 120 react in the combustor 130. Hot water vapor 6 (H ₂ O
(HT)). In other words, the power generation device of the present embodiment is a system that generates power in the process in which oxygen 4 from oxygen gas generation device 120 moves to hydrogen gas generation device 110. Therefore, in such a power generation device, water 5 in the system does not increase.

Under transient conditions such as during start-up and gear shifting, the supply amount of water 5 into the holding vessel 111 of the hydrogen gas generator 110 and the oxygen generator 2 to the hot pipe 122 of the oxygen gas generator 120 are controlled. Adjust the operation state with the supply amount of. At this time, the amounts of generated hydrogen 3 and oxygen 4 may become unbalanced, and residual gas 7 such as unreacted hydrogen 3 and oxygen 4 may be stored in buffer tank 160. here,
When increasing the output of the turbine 140, a follow-up control in which the amount of oxygen 4 generated from the oxygen gas generator 120 follows the amount of hydrogen 3 generated from the hydrogen gas generator 110 is performed. When planning for
If the advance type control is performed in which the amount of oxygen 4 generated from the oxygen gas generator 120 is reduced first and the amount of hydrogen 3 generated from the hydrogen gas generator 110 is correspondingly reduced immediately, the buffer tank 160 Inside, the residual gas 7 rich in hydrogen 3 is stored and the pressure rises.

Therefore, as shown in FIG. 6, based on the measurement result of the barometer 191, the residual gas processing device 190 operates the exhaust pump 192 so that the residual gas 7 stored in the buffer tank 160 is discharged out of the system. By operating, it is possible to suppress an increase in the atmospheric pressure in the buffer tank 160,
An increase in the outlet pressure of the turbine 140 can be suppressed to prevent a decrease in turbine efficiency.

As described above, according to the power generating apparatus of the present embodiment, the following effects can be obtained.

(1) The supply amount of water 5 to the hydrogen gas generator 110 is proportional to the supply amount of the water 5 to the hydrogen gas generator 110 and the amount of hydrogen 3 generated from the hydrogen gas generator 110. By controlling the amount, the amount of generated hydrogen 3 can be easily adjusted.

(2) Since the holding container 111 of the hydrogen gas generator 110 has a double structure of the pressure-resistant container 111a and the heat-resistant container 111c, the most expensive pressure-resistant container 111a can be reused and the running cost can be reduced. Can be reduced.

(3) Since the amount of decomposition of the oxygen generating agent 2 by heating in the hot pipe 122 of the oxygen gas generator 120 is proportional to the amount of oxygen 4 generated from the oxygen gas generator 120, the feed pump 123 By controlling the supply amount of the oxygen generating agent 2 to the hot pipe 122 by the above, the amount of generated oxygen 4 can be easily adjusted.

(4) Since the oxygen generator 2 is water-soluble,
The holding container 121 of the oxygen gas generator 120 can be reused only by washing with water, and the running cost can be reduced.

(5) Since the hydrogen 3 and the oxygen 4 are directly reacted in the combustor 130 to generate steam 6.
High-temperature steam 6 can be easily obtained, and the temperature and flow rate of steam 6 can be adjusted with good responsiveness by controlling the amount of water 5 supplied to cooling water channel 131a of main body 131 of combustor 130. it can. Therefore, the turbine 1
For example, it is possible to realize a system that is excellent in the output characteristics (high output performance, response at the time of shifting, etc.) and efficiency of the forty.

(6) The flow rate of the water 5 supplied to the hydrogen gas generator 110 can be controlled by the equivalent ratio following the flow rate of the oxygen 4 from the oxygen gas generator 120.

(8) Although the required amount of water 3 in the system fluctuates when the output is changed, a relatively small buffer tank 160 can sufficiently cope with the change, so that a very compact system can be provided.

(9) Even if the amounts of hydrogen 3 and oxygen 4 become unbalanced, the unreacted residual gas 7 is removed from the residual gas
Since it can be discharged from the buffer tank 160 to the outside by the value of 0, it is possible to prevent the efficiency of the turbine 140 from decreasing due to the increase in the internal pressure of the buffer tank 160.

<Operation / Effect> As described above, under transient conditions such as during start-up and shifting, the amounts of hydrogen 3 and oxygen 4 become unbalanced, and In some cases, residual gas 7 such as hydrogen 3 or oxygen 4 of the reaction is stored. In particular, when the output of the turbine 140 is to be increased, a follow-up control in which the amount of oxygen 4 generated from the oxygen gas generator 120 follows the amount of hydrogen 3 generated from the hydrogen gas generator 110 is performed.

For this reason, the rise in the pressure in the buffer tank 160 is suppressed, so that the rise in the outlet pressure of the turbine 140 is suppressed, and a decrease in turbine efficiency can be prevented.

Therefore, according to the power generator of the present embodiment, it is possible to obtain the same effect as that of the first embodiment described above, as well as to convert the residual gas 7 into the water 3.

Will be returned within. At this time, if correction control for slightly reducing the amount of hydrogen 3 or slightly increasing the amount of oxygen 4 is performed, the control approaches the equivalent control, and the generation amount of the residual gas 7 can be suppressed.

For this reason, the rise in the pressure in the buffer tank 160 is suppressed, so that the rise in the outlet pressure of the turbine 140 is suppressed, and a decrease in turbine efficiency can be prevented.

Therefore, according to the power generator of the present embodiment, the same effects as those of the first and second embodiments can be obtained.

When the hydrogen 3 in the residual gas 7 disappears and the oxygen 4 stops reacting in this way, the temperature of the tip of the nozzle body 494a decreases, and based on the measurement result of the oxygen thermometer 494c, The on-off valve 495 is closed to stop the supply of oxygen 4.

In the left chamber 493 b of the reaction vessel 493, no reaction occurs, and the nozzle body 4 of the hydrogen nozzle 497
Since the tip of 97a does not reach a predetermined temperature or higher, the on-off valve 498 for hydrogen is immediately closed based on the measurement result of the thermometer 497c for hydrogen, and the supply of hydrogen 3 is stopped.

On the other hand, when the residual gas 7 is rich in oxygen 4, in the left chamber 493b of the reaction vessel 493, the oxygen 4 in the residual gas 7 reacts with the hydrogen 3 to form steam 6, and the cooler 292

I do.

<Structure> [Overall] As shown in FIG. 15, a power generator according to the present embodiment comprises a hydrogen gas generator 110 for reacting metal fuel 1 and water 5 to generate hydrogen 3, Oxygen gas generator 120 for generating oxygen 2 by thermal decomposition of generator 2
And a combustor 130 that generates a steam 6 by causing a combustion reaction between the hydrogen 3 and the oxygen 4, and a motive power is generated by supplying the steam 6 to the propeller 10 via the reduction gear 101.
And a condenser 150 for cooling steam 6 discharged from the turbine 140 and returning it to water 5
And a buffer tank 160 for storing the water 5 from the condenser 150, and a water supply amount control device 17 for controlling the supply amount of the water 5 in the buffer tank 160 to the hydrogen gas generator 110.
0, a steam temperature control device 1 for controlling the temperature of steam 6
80, and a residual gas processing device 590 for processing the residual gas 7 stored in the buffer tank 160.

[Each part] << Residual gas processing device 590 >> The residual gas processing device 590 is based on a barometer 191 for measuring the pressure of the residual gas 7 stored in the buffer tank 160, and based on the measurement result of the barometer 191. An exhaust pump 192 for exhausting the residual gas 7 in the buffer tank 160 and a heat-resistant material (for example, provided in the holding container 111 of the hydrogen gas generator 110 and connected to the exhaust pump 192 as shown in FIG. 16) A residual gas injection nozzle 593 made of tungsten or the like) and the barometer 19
And a controller 594 for controlling the driving of the feed pump 123 of the oxygen gas generator 120 based on the measurement result in Step 1.

That is, the exhaust pump 192 is connected to the barometer 1
When the measurement result at 91 becomes equal to or higher than a predetermined pressure, the operation is performed so as to supply the residual gas 7 from the residual gas injection nozzle 593 into the holding container 111 of the hydrogen gas generator 110, while the controller 594 operates the barometer. When the measurement result at 191 is equal to or higher than a predetermined pressure higher than the operating pressure of the exhaust pump 192,
The drive of the feed pump 123 is controlled so as to increase the supply amount of the oxygen generating agent 2 to the hot pipe 122 of the oxygen gas generator 120 per unit time.

In this embodiment, the exhaust gas pump 192, the residual gas injection nozzle 593, and the like constitute a residual gas supply unit, and the controller 594 and the like constitute an oxygen generation amount control unit.

<Operation / Effect> When the generation amounts of hydrogen 3 and oxygen 4 become unbalanced and residual gas 7 such as unreacted hydrogen 3 and oxygen 4 accumulates in buffer tank 160,
Based on the measurement result of the barometer 191, the exhaust pump 19
2 transfers the residual gas 7 in the buffer tank 160 from the residual gas injection nozzle 593 to the holding vessel 11
Feed within 1.

At this time, if the residual gas 7 is rich in oxygen 4, it reacts with the metal fuel 1 and is adsorbed by the metal fuel 1, so that the residual gas 7 decreases and the pressure in the buffer tank 160 increases. Can be suppressed.

On the other hand, if the residual gas 7 is rich in hydrogen 3, the residual gas 7 is sent out from the hydrogen gas generator 110 together with the hydrogen 3 generated by the reaction between the metal fuel 1 and the water 5, and supplied again into the combustor 130. Since it returns to the buffer tank 160 again through the turbine 140 and the condenser 150 together with the steam 6, the residual gas 7 is further stored in the buffer tank 160 without decreasing.

As the residual gas 7 further accumulates in the buffer tank 160 as described above, the controller 594 controls the oxygen gas generator 120 based on the measurement result of the barometer 191.
Is controlled so as to increase the supply amount of the oxygen generating agent 2 to the hot pipe 122 per unit time by the supply pump 123, and the amount of oxygen 4 supplied to the combustor 130 is increased. The residual gas 7 is reduced by reacting with the increased amount of oxygen 4, and the rise of the atmospheric pressure in the buffer tank 160 is suppressed.

That is, as shown in FIG. 17, when the residual gas 7 is rich in oxygen 4, the residual gas 7 is absorbed by the metal fuel 1, and when the residual gas 7 is rich in hydrogen, the amount of generated oxygen 4 is increased. Thus, the residual gas 7 is reduced.

Therefore, an increase in the outlet pressure of the turbine 140 can be suppressed, and a decrease in turbine efficiency can be prevented.

Therefore, according to the power generating apparatus of the present embodiment, it is possible to obtain the same effect as in the case of the above-described fourth embodiment, and it is also possible to obtain hydrogen for some reason during steady operation. Even if the supply amounts of 3 and oxygen 4 become unbalanced and either hydrogen 3 or oxygen 4 becomes rich, a simpler structure than in the case of the fourth embodiment described above is used. be able to.

In this embodiment, when the residual gas 7 is rich in hydrogen 3, the supply pump 123 of the oxygen gas generator 120 is controlled so as to increase the amount of generated oxygen 4. As shown in FIG. 18, it is also possible to control the water supply amount control valve 172 of the water supply amount control device 170 so as to reduce the amount of hydrogen 3 generated in the hydrogen gas generator 110.

In the present embodiment, the controller 594 controls the hot pipe 122 by the feed pump 123 of the oxygen gas generator 120 based on the measurement result of the barometer 191.
Is controlled so as to increase the supply amount of the oxygen generating agent 2 per unit time. For example, when a hydrogen gas detector is provided in the buffer tank 160 and the hydrogen gas detector detects hydrogen 3 having a predetermined concentration or more. In addition, the controller 594 controls the hot pipe 1 by the feed pump 123 of the oxygen gas generator 120.
It is also possible to control so as to increase the supply amount of the oxygen generating agent 2 to the unit 22 per unit time.

Further, in each of the above-described embodiments, the propeller 102 is driven to rotate by the turbine 140 via the speed reducer 101. For example, as shown in FIG. Generator 10
3 can be connected to connect a motor 105 via an inverter 104 or a secondary battery 107 via an AC / DC converter 106 to connect various electric devices 108.

The power generator according to the present invention comprises an oxygen gas generating means for generating oxygen gas, a hydrogen gas generating means for generating hydrogen gas, and a reaction between the hydrogen gas and the oxygen gas to generate steam. A combustor for supplying the steam, a turbine for generating power, a condenser for cooling the steam discharged from the turbine and returning it to water, and a buffer for storing the water from the condenser A tank for holding the metal fuel that generates the hydrogen gas when the hydrogen gas generating unit reacts with water; and a water supply unit that supplies the water in the buffer tank to the holding unit. Therefore, the following effects can be obtained.

(1) Since the amount of water supplied to the holding means of the hydrogen gas generating means and the amount of hydrogen gas generated from the holding means of the hydrogen gas generating means are in a proportional relationship, the amount of hydrogen is controlled by controlling the water supply means. The amount of generated gas can be easily adjusted.

(2) Since hydrogen gas and oxygen gas are reacted in the combustor to generate steam, high-temperature steam can be easily obtained, and the supply amount of cooling water for cooling the combustor. By controlling the temperature, the temperature and flow rate of steam can be adjusted with good responsiveness, so that a system excellent in output characteristics (high power, responsiveness during shifting, etc.) and efficiency of the turbine can be realized.

(3) The flow rate of water supplied to the holding means of the hydrogen gas generating means can be controlled by the equivalent ratio following the flow rate of the oxygen gas from the oxygen gas generating means.

(4) The water vapor generated by the reaction of the hydrogen gas and the oxygen gas in the combustor is used in the turbine, then returned to the water in the condenser and reused for generating the hydrogen gas. In addition, surplus water is not constantly generated.

(5) Although the required amount of water in the system fluctuates when the output is changed, a relatively small buffer tank can sufficiently cope with the change, so that a very compact system can be realized.

Further, since the residual gas processing means for processing the residual gas stored in the buffer tank is provided, it is possible to suppress an increase in the pressure in the buffer tank and to reduce the efficiency of the turbine due to an increase in the internal pressure of the buffer tank. Can be prevented.

If the residual gas processing means includes residual gas discharging means for discharging the residual gas to the outside based on the pressure of the residual gas, the unreacted residual gas is discharged from the buffer tank to the outside of the system. Since the discharge can be performed, it is possible to easily prevent a decrease in turbine efficiency due to an increase in the internal pressure of the buffer tank.

Further, based on the pressure of the residual gas stored in the cooler, the lower end of which is connected to the upper part of the buffer tank, the reaction vessel connected to the upper end of the cooler, Oxygen supply means for supplying a portion of the oxygen gas from the oxygen gas generation means into the reaction vessel, if the residual gas is rich in hydrogen, the residual gas is burned to form water in the buffer tank. Since the pressure can be returned, an increase in the atmospheric pressure in the buffer tank can be suppressed, and a decrease in turbine efficiency due to an increase in the outlet pressure of the turbine can be prevented in a completely closed cycle.

Further, based on the pressure of the residual gas stored in the cooler having the lower end connected to the upper part of the buffer tank, the reaction vessel connected to the upper end of the cooler, and the residual gas processing means, Hydrogen supply means for supplying a part of the hydrogen gas from the hydrogen gas generation means into the reaction vessel, if the residual gas is rich in oxygen, the residual gas is burned into the buffer tank as water. Since the pressure can be returned, an increase in the air pressure in the buffer tank can be suppressed, and a decrease in turbine efficiency due to an increase in the outlet pressure of the turbine can be prevented in a completely closed cycle.

Further, the residual gas processing means includes a cooler having a lower end connected to an upper portion of the buffer tank, and a first chamber having a lower portion connected to an upper end of the cooler and having only the lower side communicated with the inside. A reaction vessel having a second chamber, and oxygen supply means for supplying a part of the oxygen gas from the oxygen gas generation means to the first chamber of the reaction vessel based on the pressure and temperature in the reaction vessel. A hydrogen supply unit that supplies a part of the hydrogen gas from the hydrogen gas generation unit to the second chamber of the reaction container based on the pressure and the temperature in the reaction container. Regardless of whether it is hydrogen-rich or oxygen-rich, the residual gas can be burned and returned to the buffer tank as water,
It is possible to suppress an increase in the pressure in the buffer tank and prevent a decrease in turbine efficiency due to an increase in the outlet pressure of the turbine in a completely closed cycle.

Further, the residual gas processing means supplies residual gas to the holding means of the hydrogen gas generating means based on the pressure of the residual gas, and a residual gas supply means for supplying the residual gas to the hydrogen gas generating means. If the residual gas is oxygen-rich, the residual gas reacts with the metal fuel if the residual gas is oxygen-rich. On the other hand, when the residual gas is hydrogen-rich, the amount of oxygen gas generated increases and is supplied to the reaction and decreases, so that the pressure increase in the buffer tank can be suppressed, and the turbine outlet Preventing a decrease in turbine efficiency due to an increase in pressure can be realized in a completely closed cycle.

Further, the residual gas processing means supplies the residual gas to the holding means of the hydrogen gas generating means based on the pressure of the residual gas, and the residual gas supply means supplies the residual gas to the hydrogen gas generating means based on the pressure of the residual gas. Water supply amount control means for controlling the supply amount of water into the holding container by the water supply means of the hydrogen gas generator, if the residual gas is oxygen-rich, the residual gas is metal. While reacting and decreasing with fuel,
When the residual gas is rich in hydrogen, the amount of hydrogen gas generated decreases and is reduced by the reaction with oxygen gas, so that the pressure increase in the buffer tank can be suppressed, and the turbine outlet pressure can be reduced. Preventing a decrease in turbine efficiency due to an increase can be realized in a completely closed cycle.
