Abstract

Abstract A gas turbine suction air cooling system includes a gas turbine, a suction air cooler for cooling the outside air to be drawn into the gas turbine, an air-cooling coil for feeding chilled water so as to cool the outside air drawn into the suction air cooler, and absorption chillers for feeding the chilled water to the air-cooling coil. The air-cooling coil is divided into a plurality of coil lines, and the air-cooling coil, disposed closest to the outside air, is connected to the absorption chiller for feeding the chilled water of highest temperature, and the other air-cooling coil, disposed closest to the gas turbine, is connected to the absorption chiller for feeding the chilled water of lowest temperature. The system having such as a construction can be made small in size and high in efficiency.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 139 words
A gas turbine suction air cooling system, comprising: a gas turbine; a suction air cooler connected to the gas turbine for cooling outside air to be drawn into the gas turbine, the suction air cooler including a first coil disposed closest to the outside air and a second coil disposed closest to the gas turbine; a first absorption chiller connected to the first coil for feeding chilled water of a first temperature to the first coil; a second absorption chiller connected to the second coil for feeding chilled water of a second temperature to the second coil, the first temperature being higher than the second temperature; a cooling tower for supplying cooling chilled water; and conduits for feeding cooling chilled water from the cooling tower in series to the second absorption chiller and then to the first absorption chiller.
