660MW机组100%容量汽动给水泵项目的技术经济性分析

Technical and economic analysis on the 100% capacity steam feed pump for the 660MW unit

为了考查安徽某电厂新建2×660 MW工程中100%容量汽动给水泵项目的技术经济性,拟定了3种典型的给水泵方案,然后通过投资回收期法,推荐采用100%容量给水泵,配国产小汽轮机与进口芯,同时配独立凝汽器方案。

In order to examine the new technology and economy of water pump steam capacity of 2×660MW project in a power plant of Anhui,three kinds of typical water pump scheme were designed,and then through the investment payback period method,100%capacity water supply pump was recommended,with domestic small steam turbine and imported turbine core with independent condenser.
