PROBLEM TO BE SOLVED: To switch to the driving of an internal combustion engine of zero combustion gas exhaust to reduce the environmental pollution and to prevent the global warming, by allowing a gas turbine exhaust temperature to be close to -273 deg.C, and coagulating the water and the water vapor while using the very low temperature combustion gas as a core for fractional recovery, as the prevention of global warming is urgent need. SOLUTION: The combustion gas exhaust temperature is allowed to be closed to -273 deg.C by unlimitedly performing the combustion heat exchange by means of a combustor/heat exchanger of a steam gas turbine combined-engine, and converting the whole amount of heat, for example, the heating amount of about four times of the conventional technology, into the superheated steam under high pressure atmosphere, a unit volume mass is increased by 1700-1000 times, the total mass is increased also by the water injection, the output is increased by the condensed water, dry ice, liquid nitrogen and the like having an enormous amount of gravitational power, a vaporization film is formed with respect to a high temperature turbine blade of which the heating is secured and simplified by applying the annular-type casting of very stage, the heat consumption frictional loss is remarkably reduced, the reheat steam turbine is excluded, the approximately 80% of heat efficiency of the steam gas turbine combined-engine is achieved, a structure can be simplified, and the specific output can be remarkably increased.
