INLET AIR HEATING SYSTEMS FOR COMBINED CYCLE POWER PLANTS
First Claim
1. An inlet air heating system for a gas turbine system of a combined cycle power plant, the inlet air heating system comprising:
- a plurality of heating coil assemblies at least partially positioned within an inlet housing of the gas turbine system;
a vent valve in fluid communication with each of the plurality of heating coil assemblies, the vent valve allowing air to flow into and out of the plurality of heating coil assemblies when in an open position;
a supply line in fluid communication with the plurality of heating coil assemblies, the supply line providing water to the plurality of heating coil assemblies;
a hot water line in fluid communication with the supply line and a component of the combined cycle power plant positioned downstream of a condenser of the combined cycle power plant, the hot water line providing hot water from the combined cycle power plant to the supply line; and
a drain line in fluid communication with the plurality of heating coil assemblies and the condenser of the combined cycle power plant, the drain line providing the water from the plurality of heating coil assemblies to the condenser.

Abstract
Inlet air heating systems for combined cycle power plants and combined cycle power plants including inlet air heating systems are disclosed. The inlet air heating systems may include a plurality of heating coil assemblies partially positioned within an inlet housing of a gas turbine system, and a vent valve in fluid communication with each of the heating coils. The inlet air heating system may also include a supply line in fluid communication with the heating coils to provide water to the heating coils, and a hot water line in fluid communication with the supply line and a component positioned downstream of a condenser of the combined cycle power plant. The hot water line may provide hot water from the combined cycle power plant to the supply line. Additionally, the inlet air heating system may include a drain line in fluid communication with the heating coils and the condenser.
