PROBLEM TO BE SOLVED: To make it possible to recycle heat of combustion gas without deteriorating efficiency of a fluid motor rotation under load by converting the combustion gas discharged through an outlet of last fluid motor into rotating motion. SOLUTION: The outlet 27 of a last flow motor, a housing inlet, housing outlet, and inlet of steam chamber are connected together and linearly aligned. When being disposed on one side, with the housing inlet and the housing outlet, the turbine is enclosed thereby. A relief passage 8 for relieving combustion air is provided between the turbine blade and the housing 9. When being disposed center, a number of propellers are provided within the housing. A rotating shaft linked with the turbine or the propeller is provided with a transmission, over which a gear is provided so as to be engaged with the gear provided on the rotating shaft linked with the fluid motor. The combustion gas discharged through the housing outlet is fed to the steam chamber.
