Abstract:
In the partial-regeneration-cycle gas turbine system wherein a part of compressed air produced in a compressor (2) is extracted before a combustor (3), mixed with steam, and after being superheated by exhaust from the turbine, the mixed gas is injected into the combustor,a dual-pressure steam injection partial-regeneration-cycle gas turbine system; whereinhigh-pressure steam is used as a fluid for driving a mixer that compresses the extracted air, thereby the ratio of the extracted air to steam is increased,the gas mixture of extracted air and steam is mixed with low-pressure steam from a low-pressure exhaust heat boiler, and after the mixture of gas is superheated by exhaust heat from the turbine,the mixture of gas is injected into the combustor.
