ABSTRACT:
A combined-cycle multi-pressure reheat system employs a plurality of power generation units each having a gas turbine, a high-pressure steam turbine, a generator, a compressor and a heat recovery steam generator with a reheater. In its simplest single-shaft form, high-pressure steam is supplied to the high-pressure steam turbine and exhaust steam therefrom is supplied to a reheater of the HRSG. Intermediate-pressure steam from the intermediate section of the HRSG combines with the cold reheat steam for heating in the reheater section. The hot reheat steam is supplied from each power generation unit to the inlet of an intermediate pressure steam turbine. Low-pressure steam from a low-pressure section of the HRSG is supplied to a header where it combines with exhaust steam from the intermediate-pressure turbine to drive a low-pressure turbine. The intermediate and low-pressure turbines may be coupled to a common generator. The gas turbine may be steam cooled by routing exhaust steam from the high pressure steam turbine to the gas turbine and exhausting spent cooling steam to the intermediate pressure steam turbine.
