HRSGs for Next Generation Combined Cycle Plants - Power

Due to the higher steam flow rates and temperatures caused by the advanced gas turbines, the design pressures are higher in the HP system. In general, design pressures for an HRSG behind an F class turbine are about 14 MPa (2,000 psig). Design pressures for an HRSG behind an advanced GT are around 21 MPa (3,000 psig).
