FRESH WATER PRODUCING SYSTEM AT GAS TURBINE INLET AIR CHILLER USING LNG COOL HEAT SOURCE

摘要

The present invention relates to a fresh water producing system including an air chiller at a gas turbine inlet side using LNG cool energy and to a method thereof, and more specifically, to a technique for producing fresh water using outer air input toward the gas turbine inlet. The fresh water producing system including an air chiller at a gas turbine inlet side using LNG cool energy according to the present invention is a fresh water producing system including an air chiller at a gas turbine inlet side using the LNG cool energy of a gas turbine system including an LNG storage tank, a glycol heat exchanger, a re-vaporizing module and a gas turbine, the fresh water producing system comprising: an air chiller for receiving, via a circulation pump, refrigerant cooled by heat exchange in the glycol heat exchanger, and outputting outer air cooled by heat exchange with air introduced from the outside; a drain unit for collecting liquefied vapor generated on the surface of the air chiller while cooling air input from the outside; and a fresh water storage tank for recovering the fresh water of the liquefied vapor collected in the drain unit via a fresh water drain line using gravity and supplying the fresh water to a demanding place. According to the fresh water producing system including an air chiller at a gas turbine inlet side using LNG cool energy and the method thereof according to the present invention, time for using a fresh water power generator in a ship can be reduced.
