steam feed pump

基本解釋

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.
采用嚴(yán)格的數(shù)學(xué)推導(dǎo)，推導(dǎo)出了定熱量等效熱降法中抽汽效率的矩陣表達(dá)形式，證明了其與常規(guī)熱平衡的一致性。
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“等效熱降”和“熱量法”計(jì)算，改換為汽動(dòng)給水泵的回收年限較長，短期內(nèi)投資無法收回；
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.
總結(jié)了利用前置泵及汽動(dòng)給水泵向鍋爐上水、利用小油槍點(diǎn)火等經(jīng)濟(jì)方式啟動(dòng)300MW機(jī)組的方法，該方法在實(shí)際生產(chǎn)中取得了較明顯的節(jié)能效果。
