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。
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.
