摘要： PROBLEM TO BE SOLVED: To prevent condensation of steam in hydrogen combustion gas.
SOLUTION: Saturation temperature to steam partial pressure in combustion gas is found, and cooling water flow by a cooling water supply device 17 is adjusted for a liner temperature to be higher than the saturation temperature for controlling temperature of an inner wall (cylinder liner) of a cylinder 6. Condensation of steam in hydrogen combustion gas is thus prevented, so that adhesion of condensation water to the inner wall (cylinder liner) of the cylinder 6 is eliminated. Deterioration of performance of a hydrogen engine 1 due to large heat loss, and rupture of oil film at sliding parts (the cylinder liner and a piston ring) of a piston 7 and the cylinder 6 to generate risk of seizure are thus eliminated.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of a discharging pump in a liquefying and discharging system for high pressure combustion exhaust gas for liquefying high pressure exhaust gas generated by a high pressure combustion divide and for discharging it into high pressure water by a discharging pump. SOLUTION: A gas-liquid separator 17 is disposed between an exhaust gas condenser 8 and a discharging pump 9 of the exhaust gas system of a high pressure combustion device 5 to separate gaseous component from the condensed liquid and extracts only oxygen from the separated gaseous component by a selective filtering device 18 and the extracted oxygen is returned to the high pressure combustion device 5 by a fan 19. Therefore, the oxygen can be removed from the condensed liquid sucked by the discharging pump 9 and hence the efficiency of the discharging pump 9 can be improved and the oxygen efficiency of the combustion device can be also improved.

摘要： PROBLEM TO BE SOLVED: To increase an oxygen consumption rate so as to exhaust combustion exhaust gas without reducing the efficiency of an exhaust pump by recirculating gas separated by a gas-liquid separator provided between an exhaust gas condenser and the exhaust pump to a high pressure combustor in under-sea motor facilities for producing a motive force in a deep sea or the like. SOLUTION: In a high pressure combustor 5, fuel and an oxidation agent are mixed and burned, and heat produced by the high pressure combustor 5 is converted into a motive power by an external combustion type thermal cycle engine 6. Combustion waster gas produced at this time is cooled by an exhaust gas cooler 14, and after this is condensed and liquefied, it is exhausted into high-pressure and high-temperature water by an exhaust pump 9. In this case, gas separated by a gas-liquid separator 17 additionally provided between an exhaust gas condenser 8 and the exhaust pump 9 is recirculated to the high pressure combustor 5 by a piping 19 having a fan 18. Thus, even if the amount of oxygen is slightly larger in a mixed ratio between fuel and oxygen, since superfluous oxygen is returned to the high pressure combustor 5 and used for combustion, an oxygen consumption rate is suppressed.
