Turbo-compound engine

Abstract

Abstract PURPOSE:To contrive effective use of exhaust steam energy in a turbo-compound engine and an improvement of an output which is not restricted by mechanical strength of the engine, by providing a combustor in an exhaust duct connecting an exhaust steam turbine and an output turbine with each other. CONSTITUTION:Under a state of a low operating load an exhaust steam heater consisting of a combustor 17 and a pump 20 is not actuated and an output turbine 13 is actuated only by exhaust steam energy through exhaust steam turbine 12a. The output acts upon an engine output shaft 11 through a power transmission 14. When the operating load becomes high state by increasing the load to some extent, efficiency of the output turbine 13 is increased and strong torque is generated because the exhaust steam heated and expanded in the combustor 17 is sent into the output turbine 13.
