PROBLEM TO BE SOLVED: To improve specific power as well as heat efficiency of a gas turbine by effectively utilizing air for combustion which is compressed by heat exchange by using a swage block shaped device which serves as both a combustor and a heat exchanger. SOLUTION: Compressed air 15 for combustion is supplied to receiving ports of a device 4 which serves as both a combustor and a heat exchanger. The receiving ports are arranged by pressurizing pressure in a high level, and are formed by forming their multiple small diameters in a swage block shape. Supplied high compression air 15 is supplied from a fuel supplying means of the most upstream side of the device 4, it is burnt in the device 4 where a heat exchange heating surface area is enlarged. As a result, heat exchange is carried out, and heat exchange cooling NOx is reduced and burnt by a water cooled outer wall of a water leading pipe and a steam pipe. Combustion gas 10 formed by carrying out heat exchange for setting a combustion gas temperature to a turbine heat resistance limit temperature or less, is injected in order toward a downstream side including a first stage of an outer turbine moving blade group and a second stage of an inner turbine moving blade group through a combustion gas sump by the device 4, and thereby, large rotating power is generated.
