摘要： In a combined cycle power generation system which includes a gas turbine; a steam turbine; and a heat recovery steam generator which includes a superheater section and an evaporator section, and wherein condensate from the steam turbine is reheated in the heat recovery steam generator by exhaust gas from the gas turbine and returned via a main steam outlet to the steam turbine, a method of effecting start-up of the steam turbine comprising the steps of:a) dumping a portion of the gas turbine exhaust gas to atmosphere, while simultaneously introducing a remaining portion of the gas turbine exhaust gas to the heat recovery steam generator;b) with the main steam outlet from the heat recovery steam generator closed, extracting steam from an intermediate location in the superheater and supplying the extracted steam to the steam turbine at a temperature between about 550-1000.degree. F.; and, after the steam turbine is started and a warm-up cycle completed,c) terminating the extraction of steam from the intermediate location in the superheater and opening the main steam outlet from the heat recovery steam generator.

摘要： A method of operating a combined gas and steam turbine cycle system including a steam turbine provided with steam from at least one heat recovery steam generator having a high pressure section and a low pressure section, wherein the steam turbine includes high pressure seals and low pressure seals, includes the steps of:a) when the steam turbine is operating at a load below a self-sealing load, supplying steam at a controlled, predetermined pressure to the high and low pressure seals from the high pressure section of the heat recovery steam generator; andb) after steam from the lower pressure section of the heat recovery stem generator exceeds the predetermined pressure, supplying the high and low pressure seals with steam from the lower pressure section of the heat recovery steam generator at a pressure higher than the predetermined pressure, andc) supplying steam from the high pressure section of the heat recovery steam generator whenever a turbine metal inlet temperature exceeds a predetermined reference temperature and turbine load is less than a predetermined reference load.
