Abstract
A combined cycle power plant system, comprising a compressor; a combustor receiving air provided by the compressor; a gas turbine for expanding gas provided by the compressor; a heat recovery steam generator (HRSG) for receiving exhaust gases from the gas turbine. The heat recovery steam generator (HRSG) receives exhaust gases from the gas turbine. The HRSG includes a low pressure (LP) section; a high pressure (HP) section for receiving exhaust gases from the gas turbine and located upstream of the LP section, each of the LP and HP sections include an evaporator section. An intermediate pressure (IP) section is located between the HP and the LP sections, the IP section includes an economizer, first and second evaporators, and a water heater (34) disposed between the first and second evaporators. A fuel gas heater is provided for receiving heated water from the water heater.
