style="text-indent:25px">汽輪機(jī)的排汽壓力越低，蒸汽循環(huán)的熱效率就越高。不過排汽壓力主要取決于冷卻水的溫度，如果采用過低的排汽壓力，就需要增大冷卻水流量或增大凝汽器冷卻面積，同時(shí)末級(jí)葉片也較長。凝汽式汽輪機(jī)常用的排汽壓力為0.005～0.008兆帕。船用汽輪機(jī)組為了減輕重量，減小尺寸，常用0.006～0.01兆帕的排汽壓力。此外，提高汽輪機(jī)熱效率的措施還有，采用回?zé)嵫h(huán)、采用再熱循環(huán)、采用供熱式汽輪機(jī)等。提高汽輪機(jī)的熱效率，對(duì)節(jié)約能源有著重大的意義。大型汽輪機(jī)組的研制是汽輪機(jī)未來發(fā)展的一個(gè)重要方向，這其中研制更長的末級(jí)葉片，是進(jìn)一步發(fā)展大型汽輪機(jī)的一個(gè)關(guān)鍵。抽氣背壓式汽輪機(jī)供應(yīng)報(bào)價(jià)</p><p
