Abstract: A combined cycle system where steam discharged from a water separation unit is routed through a high pressure outlet line to a set of super-heaters and discharged from the set of super-heaters through a main outlet line of a heat recovery steam generator to be introduced into the steam turbine. An attemperating line is connected between the high pressure outlet line and the main outlet line of the heat recovery steam generator to introduce a portion of steam that is discharged from the water separation unit into the steam discharged from the set of super-heaters. The pressure difference across a control valve for steam temperature remains low in low load and/or high load applications of the combined cycle system.
