style="text-indent:25px">汽輪機(jī)裝置的熱經(jīng)濟(jì)性用汽輪機(jī)熱耗率或熱效率表示。汽輪機(jī)熱耗率是每輸出單位機(jī)械功所消耗的蒸汽熱量，熱效率是輸出機(jī)械功與所耗蒸汽熱量之比。對(duì)于整個(gè)電站，還需考慮鍋爐效率和廠內(nèi)用電。因此，電站熱耗率比單獨(dú)汽輪機(jī)的熱耗率高，電站熱效率比單獨(dú)汽輪機(jī)的熱效率低。一座汽輪發(fā)電機(jī)總功率為1000兆瓦的電站，每年約需耗用標(biāo)準(zhǔn)煤230萬(wàn)噸。如果熱效率相對(duì)值能提高1%，每年可節(jié)約標(biāo)準(zhǔn)煤 6萬(wàn)噸。因此，汽輪機(jī)裝置的熱效率一直受到重視。為了提高汽輪機(jī)熱效率，除了不斷改進(jìn)汽輪機(jī)本身的效率，包括改進(jìn)各級(jí)葉片的葉型設(shè)計(jì)(以減少流動(dòng)損失)和降低閥門(mén)及進(jìn)排汽管損失以外，還可從熱力學(xué)觀點(diǎn)出發(fā)采取措施。凝汽式汽輪機(jī)排出的蒸汽流入凝汽器，排汽壓力低于大氣壓力，因此具有良好的熱力性能。合肥汽輪機(jī)廠商</p><p
