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)(re)器(qi)(qi)(qi)(qi)的另一種模式是遠(yuan)紅外電加(jia)(jia)熱(re)(re)(re)(re)(re)裝(zhuang)置。即管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中(zhong)的內(nei)(nei)部系統中(zhong)的電加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)包(bao)裹住管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中(zhong)反應釜底部及管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的中(zhong)下部位進(jin)行加(jia)(jia)熱(re)(re)(re)(re)(re)。管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的遠(yuan)紅外電加(jia)(jia)熱(re)(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)(re)器(qi)(qi)(qi)(qi)內(nei)(nei)部系統的加(jia)(jia)熱(re)(re)(re)(re)(re)面(mian)積大，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的升溫(wen)平穩而快，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的放熱(re)(re)(re)(re)(re)均勻，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的溫(wen)度(du)控制(zhi)方便，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)可(ke)上(shang)、中(zhong)、下分段控制(zhi)，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)釜內(nei)(nei)釜壁溫(wen)度(du)易控制(zhi)，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)對釜內(nei)(nei)物燃(ran)料無任(ren)何副(fu)作用(yong)，更不會(hui)出(chu)管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中(zhong)現物料碳化現象，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)運行無噪音，無污(wu)染(ran)，管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的使(shi)用(yong)壽命長（30000小時以上(shang)），管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的節能(neng)顯著（28%以上(shang)）。
