立式管道(dao)加(jia)熱(re)器是一種對物質預(yu)先(xian)加(jia)(jia)熱的(de)節(jie)能設(she)備，它(ta)安裝在物質設(she)備之前，實現(xian)對物質直接加(jia)(jia)溫，使其在高溫中(zhong)循環加(jia)(jia)熱作用，終達到節(jie)約能源的(de)目的(de)。它(ta)廣泛(fan)應用于重油(you)，瀝青，清油(you)等燃料油(you)的(de)預(yu)先(xian)加(jia)(jia)熱的(de)場合(he)。 
    管(guan)(guan)(guan)道(dao)加(jia)(jia)熱器(qi)的(de)(de)(de)組成結構：管(guan)(guan)(guan)道(dao)加(jia)(jia)熱器(qi)有本體和(he)控(kong)制(zhi)系統(tong)兩部(bu)分組成。發(fa)熱元件采(cai)用(yong)(yong)不銹鋼鋼管(guan)(guan)(guan)做(zuo)保護套(tao)管(guan)(guan)(guan),高(gao)溫(wen)電(dian)(dian)阻合金絲,結晶(jing)氧化(hua)鎂粉，經壓縮工藝成型。控(kong)制(zhi)部(bu)分采(cai)用(yong)(yong)先(xian)進的(de)(de)(de)數字電(dian)(dian)路(lu)(lu)，集(ji)成電(dian)(dian)路(lu)(lu)觸發(fa)器(qi)、高(gao)反壓可控(kong)硅等組成可調測溫(wen)、恒(heng)溫(wen)系統(tong)，保證了電(dian)(dian)加(jia)(jia)熱器(qi)的(de)(de)(de)正(zheng)常運行(xing)。管(guan)(guan)(guan)道(dao)電(dian)(dian)加(jia)(jia)熱器(qi)是由(you)多支管(guan)(guan)(guan)狀電(dian)(dian)加(jia)(jia)熱元件、筒(tong)體、導(dao)流板(ban)等幾部(bu)分組成，管(guan)(guan)(guan)狀電(dian)(dian)熱元件是在(zai)(zai)(zai)金屬(shu)管(guan)(guan)(guan)內(nei)放(fang)入高(gao)溫(wen)電(dian)(dian)阻絲，在(zai)(zai)(zai)空(kong)隙(xi)部(bu)分緊密地填(tian)入具有良好絕緣(yuan)性和(he)導(dao)熱性能的(de)(de)(de)結晶(jing)氧化(hua)鎂粉，采(cai)用(yong)(yong)管(guan)(guan)(guan)狀電(dian)(dian)熱元件做(zuo)發(fa)熱體，具有結構先(xian)進，熱效率高(gao)，機械強度(du)好，耐腐(fu)、耐磨等特點。筒(tong)體內(nei)安裝了導(dao)流隔板(ban)，能使空(kong)氣在(zai)(zai)(zai)流通時受熱均(jun)勻。
