Atomizing air heat for attemperation

An attemperation system and an atomizing air system are integrated for a combined cycle turbine including a gas turbine 10 and a steam turbine 12. The atomizing air system 14 receives compressor discharge air for fuel atomization. The atomizing air system 14 includes an atomizing air cooler 18 that serves to cool the compressor discharge air. A heat recovery steam generator 121 receives exhaust from the gas turbine 10 and generates steam for input to the steam turbine 12 via an attemperation system. A feed water circuit 28, 30 draws feed water from the heat recovery steam generator 121 and communicates in a heat exchange relationship with the atomizing air cooler 18 to heat the feed water. The feed water circuit 28, 30 communicates the heated feed water to the attemperation system of the heat recovery steam generator 121.
