steam feed pump

基本解释

The quantitative calculation and analysis of the thermal economy for the steam feed water pump system were performed using the theory of equivalent heat drop.
采用严格的数学推导，推导出了定热量等效热降法中抽汽效率的矩阵表达形式，证明了其与常规热平衡的一致性。
According to the calculation of"equivalent enthalpy drop"and"heat quality method", if it is turned into steam feed pump, the investment recovery period is very long.
按照“等效热降”和“热量法”计算，改换为汽动给水泵的回收年限较长，短期内投资无法收回；
Several economical startup ways for 300MW units, such as, using the booster pumps and steam feed water pump to feed boiler water and igniting furnace by using small flow oil guns, were introduced.
总结了利用前置泵及汽动给水泵向锅炉上水、利用小油枪点火等经济方式启动300MW机组的方法，该方法在实际生产中取得了较明显的节能效果。
