ABSTRACT:
Surfaces of the static blades of a turbine are heated by means that a high temperature, high pressure working gas or heating gas passes through inner passages formed inside the static blades, so that the working gas which passes through interspaces defined between adjacent ones of the static blades expands nearly isothermally without a descent in temperature so as to boost an output of the turbine.
