低压省煤器水侧系统连接方案优化分析
摘要
通过比较低压省煤器改造中水侧系统不同的连接方案
得出各连接方案对机组经济性的影响。分析表明
较常用连接方案
即低压省煤器供水取自末级低压加热器出口
回水到除氧器
经济性最低。继而对其它连接方案进行可行性分析
优选出了最经济可行的连接方案。
Abstract
Through comparison of different connecting schemes in retrofitting water side system of low-pressure economizer
the influence of each connecting scheme upon the economic efficiency of unit has been obtained.Analysis shows that the economic efficiency of commonly used connecting scheme
i.e.the water supply of low-pressure economizer being taken from outlet of the final-stage low-pressure heater
and returning water to the deaeratori is the lowest
and then the feasibility of other connecting schemes has been analysed
and the most economic and feasible scheme being choised.
