管道加熱器分為兩種模式：一種是采用管道加熱器內部的法蘭式管狀電熱元件倒插在管道加熱器中的反應釜夾套中加熱導熱油，將管道加熱器中的熱能傳輸給管道加熱器內部反應釜中的化工原料。 

管道式加熱器廠家還有一種方式是直接在管道加熱器中的反應釜中插入管道加熱器中的管狀電熱元件或在管道加熱器的壁四周均勻分布電熱管。這種模式稱為管道加熱器的內熱式。管道加熱器的內熱式升溫快、效率高。

管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的另(ling)一(yi)種模式是遠紅(hong)外電(dian)加(jia)(jia)熱(re)(re)(re)(re)裝(zhuang)置。即管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中的內部系統中的電(dian)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)包(bao)裹(guo)住管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中反應釜(fu)底部及管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的中下部位進行加(jia)(jia)熱(re)(re)(re)(re)。管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的遠紅(hong)外電(dian)加(jia)(jia)熱(re)(re)(re)(re)裝(zhuang)置具有管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)內部系統的加(jia)(jia)熱(re)(re)(re)(re)面積大，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的升溫平穩而快，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的放熱(re)(re)(re)(re)均勻(yun)，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的溫度控制(zhi)(zhi)方便，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)可(ke)上、中、下分段(duan)控制(zhi)(zhi)，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)釜(fu)內釜(fu)壁溫度易控制(zhi)(zhi)，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)對釜(fu)內物燃料無任何副作用(yong)，更不會出管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中現物料碳(tan)化現象，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)運行無噪音，無污染，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的使用(yong)壽命長（30000小時以上），管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的節能顯著（28%以上）。
