联合循环热电冷联供对旧热电厂技术改造的探讨

某烧煤热电厂位于市区,因环保原因不能再生存时,利用川气东送的时机,改造为以天然气为燃料的燃机联合循环热电厂,发展热电冷联供,适应了市场需求。热电冷联供的燃机联合循环电厂比纯凝发电热效率大幅度地提高,相应的经济效益也较为显著,取得了环保效益、社会效益、热利用效益和经济效益兼顾的良好成果。

Research on the Technological Innovation from Convenrional Coal-fired Co-generation Unit to Heat, Coling and Power Co-generation Based on Combined-cycle Gas Turbine

A coal-fired co-generation power plant located in city-area cannot survive from severe environmental policy,it should changed into a gas-fired combined-cycle power plant in the type of heat,cooling and power co-generation by using Sichuan's natural Gas to suit the market-orientation.In comparison with the convenrional condensing unit,this type of co-generation based on combined-cycle will greatly improve the heating efficiency,economic benefit,environmental benefit,social benefit,etc,and achieve perfect success both in fuel-heat-utilization and cost-saving.
