【摘要】:燃?xì)廨啓C(jī)在全封閉的箱裝體中運(yùn)行時(shí),機(jī)匣輻射及法蘭處泄漏的熱空氣會使箱裝體內(nèi)溫度急劇升高,而使用雙燃料系統(tǒng)時(shí),按照防爆等級要求,附屬設(shè)備和元件的工作溫度不能超過75℃,因此有必要對箱裝體進(jìn)行有效的冷卻。對某型燃?xì)廨啓C(jī)在箱裝體中的實(shí)際運(yùn)行狀態(tài)進(jìn)行數(shù)值模擬,并與試驗(yàn)值和場站運(yùn)行記錄進(jìn)行對比,驗(yàn)證數(shù)值模擬方法的準(zhǔn)確性,證明現(xiàn)有冷卻結(jié)構(gòu)不能滿足要求。提出多種冷卻結(jié)構(gòu)的優(yōu)化方案并進(jìn)行數(shù)值模擬,結(jié)果表明:分支結(jié)構(gòu)不但可以有效解決箱體內(nèi)超溫的問題,而且可以將冷卻空氣流量減少29%,將底板附近空氣速度減小33%,可在大幅減少對能源的消耗的同時(shí)提高底板附近零部件的使用壽命。
[Abstract]:When the gas turbine is running in a fully enclosed tank, the heat air leaking from the casing and the flange will cause the temperature of the tank to rise sharply. When using the dual fuel system, the explosion proof grade is required. The working temperature of accessories and components should not exceed 75 鈩,
