冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)的(de)(de)(de)(de)(de)(de)組(zu)成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng): 冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)主要(yao)(yao)有(you)(you)(you)(you)三(san)(san)大(da)(da)部分組(zu)成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng):鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)本(ben)體(ti)(ti)、節(jie)(jie)(jie)(jie)能(neng)(neng)器(qi)(qi)(qi)、冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)。節(jie)(jie)(jie)(jie)能(neng)(neng)器(qi)(qi)(qi)是一(yi)(yi)般(ban)承壓的(de)(de)(de)(de)(de)(de),其制作(zuo)材料主要(yao)(yao)是碳鋼(gang)(gang)(gang)(gang)的(de)(de)(de)(de)(de)(de);冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)一(yi)(yi)般(ban)是常壓,用(yong)(yong)不(bu)銹(xiu)鋼(gang)(gang)(gang)(gang)制作(zuo)。因為(wei)(wei)(wei)冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)中(zhong)煙(yan)氣(qi)(qi)(qi)排(pai)(pai)煙(yan)溫度(du)(du)低(di)有(you)(you)(you)(you)**的(de)(de)(de)(de)(de)(de)冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)水(shui)(shui)(shui)生成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng),冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)水(shui)(shui)(shui)中(zhong)溶有(you)(you)(you)(you)一(yi)(yi)定(ding)量的(de)(de)(de)(de)(de)(de)酸性(xing)氣(qi)(qi)(qi)體(ti)(ti),顯酸性(xing)。若不(bu)用(yong)(yong)不(bu)銹(xiu)鋼(gang)(gang)(gang)(gang),用(yong)(yong)普(pu)通(tong)(tong)(tong)(tong)碳鋼(gang)(gang)(gang)(gang)快的(de)(de)(de)(de)(de)(de)幾個月就腐蝕(shi)壞了。 鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)本(ben)體(ti)(ti)一(yi)(yi)般(ban)采用(yong)(yong)二回(hui)程(cheng)(cheng),為(wei)(wei)(wei)了降低(di)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)高(gao)度(du)(du),有(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)廠(chang)家(jia)將回(hui)燃(ran)室作(zuo)成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)橢圓形(xing),但(dan)多數廠(chang)家(jia)還是用(yong)(yong)圓形(xing)的(de)(de)(de)(de)(de)(de)。 節(jie)(jie)(jie)(jie)能(neng)(neng)器(qi)(qi)(qi)常采用(yong)(yong)光管(guan)或鰭片(pian)(pian)管(guan)式(shi)(shi)(shi),而冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)采用(yong)(yong)鰭片(pian)(pian)管(guan)式(shi)(shi)(shi)。鰭片(pian)(pian)有(you)(you)(you)(you)螺旋(xuan)纏(chan)繞式(shi)(shi)(shi)、有(you)(you)(you)(you)螺旋(xuan)高(gao)頻焊的(de)(de)(de)(de)(de)(de)、有(you)(you)(you)(you)用(yong)(yong)鋁擠(ji)壓成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)螺旋(xuan)形(xing)的(de)(de)(de)(de)(de)(de)。為(wei)(wei)(wei)了防止腐蝕(shi)鰭片(pian)(pian)管(guan)一(yi)(yi)般(ban)作(zuo)成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)不(bu)銹(xiu)鋼(gang)(gang)(gang)(gang)的(de)(de)(de)(de)(de)(de)。有(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)廠(chang)家(jia)管(guan)子用(yong)(yong)一(yi)(yi)般(ban)的(de)(de)(de)(de)(de)(de)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)管(guan),鰭片(pian)(pian)用(yong)(yong)鋁擠(ji)壓成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng),由于(yu)(yu)鋁的(de)(de)(de)(de)(de)(de)導熱(re)效(xiao)果(guo)(guo)好(hao),成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)本(ben)較用(yong)(yong)不(bu)銹(xiu)鋼(gang)(gang)(gang)(gang)高(gao)頻焊低(di)一(yi)(yi)點,現在(zai)好(hao)多廠(chang)家(jia)廣泛采用(yong)(yong)。

一(yi)(yi)般(ban)以(yi)(yi)通(tong)(tong)(tong)(tong)過煙(yan)氣(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)溫度(du)(du)高(gao)低(di)來區(qu)別:通(tong)(tong)(tong)(tong)過節(jie)(jie)(jie)(jie)能(neng)(neng)器(qi)(qi)(qi)或冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)排(pai)(pai)煙(yan)溫度(du)(du)大(da)(da)于(yu)(yu)100℃我們就叫(jiao)節(jie)(jie)(jie)(jie)能(neng)(neng)器(qi)(qi)(qi),小于(yu)(yu)100 ℃的(de)(de)(de)(de)(de)(de)我們就叫(jiao)冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)。若煙(yan)氣(qi)(qi)(qi)溫度(du)(du)高(gao)于(yu)(yu)100 ℃,煙(yan)氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)水(shui)(shui)(shui)蒸汽(qi)就不(bu)能(neng)(neng)凝(ning)(ning)(ning)(ning)(ning)(ning)結成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)水(shui)(shui)(shui)了。無水(shui)(shui)(shui)生成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)當然不(bu)能(neng)(neng)叫(jiao)冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)了。 嚴格來說(shuo)(shuo),通(tong)(tong)(tong)(tong)過冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)排(pai)(pai)煙(yan)溫度(du)(du)在(zai)80

順(shun)便說(shuo)(shuo)一(yi)(yi)下(xia)通(tong)(tong)(tong)(tong)常把排(pai)(pai)煙(yan)溫度(du)(du)在(zai)80~100℃之間的(de)(de)(de)(de)(de)(de)叫(jiao)半冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi),但(dan)作(zuo)為(wei)(wei)(wei)銷售推(tui)廣,將半冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)說(shuo)(shuo)成(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)也是可以(yi)(yi)的(de)(de)(de)(de)(de)(de),但(dan)我們要(yao)(yao)知道這個概念,以(yi)(yi)免和內行談起來說(shuo)(shuo)外行話。 冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)與(yu)普(pu)通(tong)(tong)(tong)(tong)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)的(de)(de)(de)(de)(de)(de)比(bi)較: 冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)與(yu)普(pu)通(tong)(tong)(tong)(tong)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)相比(bi)多了節(jie)(jie)(jie)(jie)能(neng)(neng)器(qi)(qi)(qi),我們在(zai)普(pu)通(tong)(tong)(tong)(tong)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)后加冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)器(qi)(qi)(qi)是否也能(neng)(neng)達(da)到冷(leng)(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)(ning)(ning)鍋(guo)(guo)(guo)爐(lu)(lu)(lu)(lu)的(de)(de)(de)(de)(de)(de)效(xiao)果(guo)(guo)呢(ni)?這里就有(you)(you)(you)(you)個設(she)計(ji)的(de)(de)(de)(de)(de)(de)經濟性(xing)問題了。
