汽輪機(jī)熱平衡圖功率的核算方法

"對汽輪機(jī)熱平衡圖中功率的核算，首先要先有廠家給出的熱平衡圖例，然后把各熱力參數(shù)數(shù)值按下表整理成列，查看技術(shù)協(xié)議中發(fā)電機(jī)效率、機(jī)械效率后，可獲得三缸做功量，發(fā)電機(jī)功率值是否和設(shè)計(jì)一致。

結(jié)果的少許偏差原因由于熱力參數(shù)數(shù)值保留位數(shù)的差別，和發(fā)電機(jī)效率、機(jī)械效率的影響都比較大。

若未下載EXCEL計(jì)算焓熵的所加載的宏，計(jì)算焓熵可能不顯示，打開EXCEL焓熵的計(jì)算未顯示，可通過各種途徑查詢焓熵填空，計(jì)算步驟和思想不受影響。",,,,,,,,,,,,,,,,,
