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)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)的另一種模式(shi)是遠紅外電(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)裝置。即管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)中(zhong)的內(nei)部(bu)(bu)系統(tong)中(zhong)的電(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)包裹住管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)中(zhong)反應釜(fu)底部(bu)(bu)及管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)的中(zhong)下(xia)部(bu)(bu)位(wei)進行(xing)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)。管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)的遠紅外電(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)裝置具有管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)內(nei)部(bu)(bu)系統(tong)的加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)面積大，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)的升溫平穩而快，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)的放熱(re)(re)(re)(re)均勻，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)的溫度控(kong)(kong)(kong)制方(fang)便，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)可上、中(zhong)、下(xia)分段控(kong)(kong)(kong)制，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)釜(fu)內(nei)釜(fu)壁溫度易控(kong)(kong)(kong)制，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)對(dui)釜(fu)內(nei)物燃料(liao)無(wu)任(ren)何副作(zuo)用(yong)，更不會(hui)出管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)中(zhong)現物料(liao)碳化(hua)現象(xiang)，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)運行(xing)無(wu)噪音(yin)，無(wu)污(wu)染，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)的使用(yong)壽命長（30000小時(shi)以(yi)(yi)上），管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)的節能顯著(zhu)（28%以(yi)(yi)上）。
