摘要
给水泵出口再热减温水对机组经济性的影响很大。对经济性的定量分析中,采用较多的是等效热降的方法。对等效热降中分析给水泵出口再热减温水影响定量分析的公式重新进行了推导,并与经常使用的计算公式进行了比较,指出了常用计算公式中的错误。结合具体机组,给出了给水泵出口再热减温水对经济性影响的算例。
The equivalent power output method was widely used for analyzing the impact of the reheat spray from feedwater pump outlet on power generation unit efficiency. The formulas used for the analyzing were rededuced and compared with the popularly used formulas, and the errors in popular formulas were described. An example was given for calculation of the impact of reheat spray from feedwater pump outlet.
