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)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)另一(yi)種模式是遠(yuan)紅(hong)外電(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)裝(zhuang)置。即管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)中(zhong)的(de)內(nei)部(bu)(bu)系統中(zhong)的(de)電(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)包裹住管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)中(zhong)反(fan)應釜底(di)部(bu)(bu)及(ji)管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)中(zhong)下部(bu)(bu)位進行加(jia)(jia)(jia)(jia)熱(re)(re)(re)。管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)遠(yuan)紅(hong)外電(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)裝(zhuang)置具有(you)管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)內(nei)部(bu)(bu)系統的(de)加(jia)(jia)(jia)(jia)熱(re)(re)(re)面(mian)積(ji)大，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)升溫平(ping)穩而快，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)放熱(re)(re)(re)均勻，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)溫度(du)控(kong)制方便，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)可上、中(zhong)、下分段控(kong)制，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)釜內(nei)釜壁溫度(du)易(yi)控(kong)制，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)對釜內(nei)物燃料(liao)無(wu)任何(he)副作用，更(geng)不會(hui)出管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)中(zhong)現物料(liao)碳(tan)化現象，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)運行無(wu)噪音，無(wu)污染，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)使(shi)用壽命長（30000小(xiao)時以上），管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)節能(neng)顯著(zhu)（28%以上）。
