Description of the Related Art In recent years, a concept and an elemental research have been made on an inert gas circulating internal combustion power system using hydrogen-oxygen combustion. This power system supplies hydrogen and oxygen at a theoretical mixing ratio into an inert gas for complete combustion, uses the generated heat to extract power, and condenses the generated steam in a heat exchanger to remove it as water. While doing
Inert gas is a system that circulates and reuses.

要がある、などの問題もある。[0003] Such a power system is advantageous in that it does not generate nitrogen oxides because it does not directly use oxygen in the atmosphere for combustion, but in order to construct it as a realistic power system. , There are various problems. For example,
The system will not reach a steady state unless the hydrogen and oxygen contained in the system are completely combusted and taken out as water. In particular, there is a time delay from the start of gas supply at startup to ignition, and unburned gas will flow, but if the time delay is long and the supply flow rate is large, the pressure in the system will rapidly rise, The combustion temperature becomes too high due to the burning of the unburned gas. Furthermore, if unburned gas remains in the system and its amount increases gradually, the pressure in the system will continue to rise abnormally, and it will be necessary to control it by some means. There are also problems.

It is necessary to prevent overheating of the temperature, prevent a decrease in specific output, and prevent a decrease in efficiency during steady operation.

The generated water vapor is removed from the circulation system in the condenser,
In a circulation type power system in which an inert gas is circulated, the oxygen supply amount is controlled based on the hydrogen and oxygen concentrations in the circulation system detected by the hydrogen sensor and the oxygen sensor, so that the circulation is performed at least when the system is started. By controlling the excess oxygen in the system and adjusting the cooling capacity of the condenser based on the temperature on the outlet side of the combustor, the outlet temperature of the condenser is controlled, thereby It is characterized in that the remaining steam concentration is controlled to control the combustion temperature in the combustor.

This makes it possible to shorten the ignition delay as much as possible.

It will be possible. In addition, when hydrogen and oxygen are supplied to the inert gas of the monoatomic molecule gas for combustion, the combustion temperature tends to be high, and efficient combustion can be performed with a small amount of fuel, but the specific output cannot be increased. On the other hand, if the water vapor concentration in the circulation system is increased as described above, the specific output can be increased.

可能になる。In the circulation type power system having the above structure, the control as described below is performed. First,
To improve the ignition performance at startup and eliminate the ignition delay,
The circulation system 1 is controlled so that oxygen is excessive at least when the system is started. When hydrogen and oxygen are brought into contact with each other for combustion, if they are fed at a theoretical mixing ratio, the two do not mix uniformly and the ignition performance naturally deteriorates. Therefore, at the time of ignition, oxygen is supplied in advance to create an atmosphere with good ignitability, or when the system is stopped, some oxygen is supplied from the supply pipe 4 even after the hydrogen is stopped, and some oxygen is restarted. Leave it. This makes it possible to improve the ignition performance, shorten the ignition delay, and avoid the pressure increase in the system due to unburned gas at the time of startup.

For example, hydrogen and oxygen may be supplied through the flow rate adjusting valves 10 and 11 of the supply pipes 3 and 4 and the ignition may be performed at the same time. If the oxygen concentration is not sufficient, the flow rate fine adjustment valve 12 of the oxygen bypass pipe 4a is adjusted to supply the required amount of oxygen in advance.

なるように設定しておくのが望ましい。Further, each flow rate adjusting valve has a unique flow rate characteristic, and it is extremely difficult to accurately supply hydrogen and oxygen at a theoretical mixing ratio even in a steady state. Therefore, even during the steady operation of the system, the hydrogen sensor 21 and the oxygen sensor 22 monitor the concentration of hydrogen and oxygen in the system before the combustor 2, and the oxygen is supplied through the flow rate fine adjustment valve 12 of the oxygen bypass pipe 4a. Supply and adjust to the theoretical mixing ratio. For that purpose, the flow rate adjusting valve 10 of the supply pipe 3
It is desirable to set the amount of hydrogen supplied by the above method to be slightly smaller than the theoretical mixing ratio as compared with the amount of oxygen supplied by the flow rate adjusting valve 11 of the supply pipe 4.

A control circuit for controlling the valve 12 and controlling the timing of starting the hydrogen-oxygen supply is provided, and the operation is performed by this control circuit.

Therefore, the residual water concentration remaining in the circulation system 1 can be controlled. The residual water concentration in this system can be used for preventing the temperature of the inlet side or the outlet side of the turbine 5 which is the outlet side of the combustor 2 from increasing more than necessary in the following manner.

る。That is, when hydrogen and oxygen are supplied into the monoatomic molecule inert gas for combustion, the combustion temperature becomes particularly high. However, when the residual water concentration in the circulation system 1 increases, the heat capacity increases in accordance with the water concentration, so that the combustion temperature can be lowered. Therefore, the combustion temperature in the combustor 2 can be controlled by controlling the outlet temperature of the condenser 7 by controlling the inlet or outlet temperature of the turbine 5 and controlling the concentration of water vapor remaining in the system.
To control the temperature on the outlet side of the condenser 7, the temperature sensor 23 provided on the outlet side of the turbine 5 may control the outlet temperature of the condenser 7 via a temperature control circuit. The outlet temperature of the condenser 7 is controlled by adjusting the flow rate of the cooling fluid under the control of the flow rate control valve 14.

The specific output cannot be increased, on the other hand,
If water is included in the inert gas, the specific output can be increased. The increase in the residual water content in the system for temperature control described above can be effectively utilized in this respect as well. That is, in order to keep the gas temperature in the turbine 5 constant,
The specific output can be increased by allowing water to remain in the system and increasing the amount of heat for heating.
