Combined cycle power plant and method for operating such a combined cycle power plant

摘要: The invention relates to a combined cycle power plant (10a) comprising gas turbine (11a,b) the exhaust outlet of which is connected heat recovery steam generator (19), part water/steam (35), whereby, for having large reserve and at same time higher design performance when operated base load, (11a) designed with injection capability (26) augmentation. For improved optimized being comprises least one combustor (15, 16), compressor (12) providing cooling air that (11a,b), extracted from cooled down in cooler (17, 18). generated said 18), whereby injected into an side inlet or 18) and/or directly 16). (19) equipped supplementary firing (22, 22´), single stage (22) increase high pressure production augmentation as grid required.
