Abstract
A supercritical steam combined cycle system including a gas turbine; a supercritical steam turbine system including a supercritical section, a high pressure section, an intermediate pressure section and at least one low pressure section; and a supercritical steam heat recovery steam generator (HRSG) for receiving exhaust gas from the gas turbine for heating fluid from the steam turbine system. The HRSG includes a supercritical evaporator arranged to supply steam to a superheater between the supercritical evaporator and the inlet of the HRSG and a reheater receiving cold reheat steam from and returning reheated steam to the steam turbine system. The reheater includes a first section disposed downstream of and a second section disposed upstream of the supercritical evaporator along the exhaust gas flow path. Cool reheat steam from the steam turbine system is received by the first reheater section and steam leaving the first reheater section is supplied to the second reheater section upstream of the supercritical evaporator.
