MARINE LNG STORAGE AND COMBINED CYCLE POWER GENERATING UNIT

摘要

PURPOSE: An offshore LNG storage and combined cycle power generator is provided to make a gas storage facility and gas power facility requiring for constructing a gas power plant in areas where gas infrastructure does not exist to one facility and to reduce components required for the construction of the gas power plant by arranging the gas plant facility on the top or inside the offshore gas storage facility. CONSTITUTION: An offshore LNG storage and combined cycle power generator comprises a storage tank(120), an evaporation unit(130), a gas turbine(140), a heat recovery steam generator(150), a steam turbine(160), and a generator(170). The storage tank is arranged in a hull and stores LNG. The evaporation unit vaporizes the LNG supplied from the storage tank. The gas turbine is operated by using natural gas vaporized in the evaporation unit as fuel. The heat recovery steam generator generates steam using waste heat of exhaust gas generating from the gas turbine. The steam turbine is operated by the steam generating in the heat recovery steam generator. The generator obtains the power of the gas turbine and the steam turbine to generate electricity.
