    • 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.

    • PURPOSE:To hasten a speed response at an underwater traveling body equipped with a Rankine cycle type engine by controlling a fuel supply quantity through the use of the differential value of a speed control signal. CONSTITUTION:A control signal 21 to a water feed pump return flow regulation valve 5, is synthesized from a signal obtained by means of a PID controller 19 through the variation of a pressure set value 15 and a turbine entrance pressure 8, and the signal of a water feed pump return flow regulation valve opening set value 17. Also, a control signal 22 to a fuel flow regulation valve 6, is synthesized from a signal obtained by means of a PID controller 20 through the variation of a temperature set value 16 and a turbine entrance temperature 7, and the signal of a fuel flow regulation valve opening set value 18, and a signal obtained by multiplying the differential value of a speed command 9 by means of a differential device 23 by a gain 24. As a result, the control signal 22 of the fuel flow changes faster than the control signal 21 of the water feed flow, so the ascent of the turbine entrance temperature 7 is restrained, and the speed response of an underwater traveling body can be made faster.
