產(chan)品詳情
空(kong)氣(qi)預(yu)熱(re)(re)(re)器(qi)也被(bei)簡稱為空(kong)預(yu)器(qi),是(shi)提高鍋(guo)(guo)爐(lu)熱(re)(re)(re)交換性能,降低(di)熱(re)(re)(re)量損耗的*種預(yu)熱(re)(re)(re)設(she)備。空(kong)氣(qi)預(yu)熱(re)(re)(re)器(qi)的作用,是(shi)將(jiang)鍋(guo)(guo)爐(lu)尾部煙(yan)道中(zhong)排出的煙(yan)氣(qi)中(zhong)攜帶的熱(re)(re)(re)量,通過(guo)散熱(re)(re)(re)片傳導到進入鍋(guo)(guo)爐(lu)前的空(kong)氣(qi)中(zhong),將(jiang)空(kong)氣(qi)預(yu)熱(re)(re)(re)到*ding的溫度(du)。
*般簡稱(cheng)為空預器(qi)。多用于燃煤電站(zhan)鍋(guo)爐(lu)。可分為管箱(xiang)式(shi)(shi)、回轉式(shi)(shi)兩種,其(qi)中(zhong)回轉式(shi)(shi)又分為風罩回轉式(shi)(shi)和(he)受(shou)熱面(mian)回轉式(shi)(shi)兩種。電站(zhan)鍋(guo)爐(lu)較常(chang)(chang)采用受(shou)熱面(mian)回轉式(shi)(shi)預熱器(qi)。在鍋(guo)爐(lu)中(zhong)的應用*般為兩分倉(cang)(cang)、三分倉(cang)(cang)、四分倉(cang)(cang)式(shi)(shi),其(qi)中(zhong)四分倉(cang)(cang)較常(chang)(chang)用于循(xun)環(huan)流化(hua)床鍋(guo)爐(lu)中(zhong)。
