Abstract

A gas turbine power augmentation system and method are provided. The system includes a chiller, a controller, a heat exchanger, and a gas turbine inlet air flow. The chiller may be operable to chill a coolant flow using energy from a heat source. The controller may be operably connected to the chiller and configured to regulate operation of the chiller in relation to at least one environmental condition. The heat exchanger may be in fluid communication with the chiller and configured to allow the coolant flow to pass through the heat exchanger. The gas turbine inlet air flow may be directed through the heat exchanger before entering a gas turbine inlet, allowing the air flow to interact with the coolant flow, thereby cooling the air flow.

Description

technical field [0001] The subject matter disclosed herein relates generally to gas turbines, and more particularly, to methods and apparatus for operating gas turbines. Background technique [0002] Gas turbines are widely used in fields such as power generation. A conventional gas turbine system includes a compressor, which compresses ambient air; a combustor, which is used to mix the compressed air with fuel and combust the mixture; and a turbine, which is driven by the combustion mixture to generate power and exhaust. [0003] Various strategies are known in the art for increasing the amount of power a gas turbine can produce. One way to increase the power output of a gas turbine is by cooling the inlet air before it is compressed in the compressor. Cooling causes the air to have a higher density, resulting in a higher mass flow rate into the compressor. The higher mass flow rate of air entering the compressor allows more air to be compressed, allowing the gas turbine...
