Abstract

본 발명은 가스터어빈의 동력증강방법과 장치에 관한 것으로, 가스터어빈 시스템에 의하여 생산된 동력이 이 시스템의 메인콤프레사에 공급되는 주위공기를 압축하여 공급공기의 온도와 압력상승을 유도하는 프리콤프레사 장치에 의하여 증강된다.The present invention relates to a method and a device for increasing power of a gas turbine, wherein the power produced by the gas turbine system compresses the ambient air supplied to the main compressor of the system to induce a rise in temperature and pressure of the supply air. Augmented by Lesa apparatus.

메인콤프레사에 공급되는 공기는 가스터어빈의 메인콤프레사에 대한 유입구측에서 공급공기의 온도를 낮추는 기계적인 냉각시스템을 이용하여 냉각된다.The air supplied to the main compressor is cooled using a mechanical cooling system that lowers the temperature of the supply air at the inlet side of the gas turbine main compressor.

메인콤프레사에 의하여 압축된 공기가 압축공기를 가열하여 부하에 공급되고 메인콤프레사를 구동시키는 터어빈에 공급되는 고은가스를 생성하는 연소기에 공급된다. 고온배기가스가 증기를 생산하는 보일러에 공급되고, 상기 증기는 부하를 공급하는 증기터어빈에 공급된다.The air compressed by the main compressor is supplied to a combustor that generates compressed gas which is supplied to a load by heating compressed air and supplied to a turbine driving the main compressor. The hot exhaust gas is supplied to a boiler producing steam, and the steam is supplied to a steam turbine supplying a load.

압축공기를 증발냉각기는 대신에 냉각기를 이용하는 것이 주위공기의 습윤조건에 영향받지않는 장치를 제공하므로 유리하다.Compressed air evaporative coolers are advantageous because the use of a cooler instead provides an apparatus that is not affected by the wetting conditions of the ambient air.
