Abstract
An inlet air heating system for a gas turbine system includes an inlet heat exchanger configured to be positioned upstream of a compressor of the gas turbine system. The inlet air heating system also includes a heating loop fluidly coupled to the inlet heat exchanger. The heating loop is configured to provide heating fluid to the inlet heat exchanger, and the inlet heat exchanger is configured to facilitate transfer of heat from the heating fluid to an airflow into the compressor. Furthermore, the inlet air heating system includes a heat transfer assembly configured to receive cooling tower fluid from a fluid pathway extending between a steam condenser and a cooling tower. The heat transfer assembly is configured to facilitate transfer of heat from the cooling tower fluid to the heating fluid.
