PROBLEM TO BE SOLVED: To provide a partial regenerative twin-fluid gas turbine, capable of increasing extracted air remarkably without increasing a driving vapor pressure thereby increasing an air/vapor suction ratio remarkably, reducing the energy loss of a waste heat recovering unit and improving a power generating efficiency, as well as a combustor therefor. SOLUTION: In a partial reproducing type twin-fluid gas turbine wherein a part of air, compressed by a compressor 2, is extracted before a combustor 3 and is mixed into vapor, then, the mixture is heated by the waste heat of a turbine and, thereafter, the mixture gas is poured into a combustor, an air extraction port (a) for the compressor and an air introducing port (c) for the combustor are provided to introduce combustion air for the combustor into the combustor directly and extract remaining compressed air through the air extraction port (a) to mix the same into vapor and heat the mixture by the waste heat of the turbine, then, the mixture is introduced into the air introducing port (c).
