摘　　要：LNG作为液态形式的天然气,在用于联合循环机组运行时需要经过气化,在这期间将产生大量冷能,将这些冷能应用在电厂生产环节,可以提高电厂的运行效率。研究某联合循环机组将此部分冷能应用于压气机入口空气温度冷却、制冷站供冷及闭式水系统供冷中的可行性。LNG,as a liquid form of natural gas,needs to undergo gasification when used for the operation of combined cycle units,which will generate a large amount of cold energy.Applying this cold energy to the production process of power plants can improve their operational efficiency.This paper studies the feasibility of applying this portion of cold energy to the cooling of compressor inlet air temperature,refrigeration station cooling,and closed water system cooling in a combined cycle unit.
