热电联产机组乏汽余热利用项目可行性分析

Feasibility Analysis on the Surplus Heat Utilization of Steam Exhaust in the Cogeneration Unit

汽轮机余热利用项目前在国内已经有小范围应用,该项目采用吸收式热泵技术对汽轮机乏汽余热进行利用,用于集中供热,提高电厂供热能力,并且达到节能减排的目的。在调研和考察的基础上,通过可靠性和经济性论证,认为该方案在工艺技术上是可行的。

The project of surplus heat utilization from the turbine has been applied in a small scale in China.The project takes advantage of the absorption heat pump technology to make use of the surplus heat of exhaust steam from the turbine to save energy and protect environment by central heating and improving the heating capacity of the power plant.Based on the investigation and study,the reliability and economy of this project have been proved.The scheme is technically feasible.
