INLET AIR HEATING SYSTEM FOR A GAS TURBINE SYSTEM

An inlet air heating system for a gas turbine system (10) includes an inlet heat exchanger (52) configured to be positioned upstream of a compressor (16) of the gas turbine system (10). The inlet air heating system also includes a heating loop (56) fluidly coupled to the inlet heat exchanger (52). The heating loop (56) is configured to provide heating fluid (58) to the inlet heat exchanger (52), and the inlet heat exchanger (52) is configured to facilitate transfer of heat from the heating fluid (58) to an airflow into the compressor (16). Furthermore, the inlet air heating system includes a first heat transfer assembly (60) configured to receive cooling tower fluid (48) from a fluid pathway (44) extending between a steam condenser (39) and a cooling tower. The heat transfer assembly is configured to facilitate transfer of heat from the cooling tower fluid (48) to the heating fluid (58). The inlet air heating system also includes a second heat transfer assembly (68) configured to receive heated fluid from a steam turbine system (28), wherein the second heat transfer assembly is configured to facilitate transfer of heat from the heated fluid to the heating fluid (58).
