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)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)的另(ling)一(yi)種(zhong)模式是遠紅外電(dian)(dian)加(jia)熱(re)(re)裝置。即管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)中的內部(bu)系統(tong)中的電(dian)(dian)加(jia)熱(re)(re)器(qi)包裹住管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)中反應釜(fu)(fu)底部(bu)及管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)的中下部(bu)位進行(xing)加(jia)熱(re)(re)。管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)的遠紅外電(dian)(dian)加(jia)熱(re)(re)裝置具有管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)內部(bu)系統(tong)的加(jia)熱(re)(re)面積大(da)，管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)的升溫平穩而快，管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)的放熱(re)(re)均勻，管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)的溫度控(kong)(kong)制方便，管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)可上、中、下分段控(kong)(kong)制，管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)釜(fu)(fu)內釜(fu)(fu)壁溫度易(yi)控(kong)(kong)制，管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)對釜(fu)(fu)內物(wu)燃料無(wu)任何副(fu)作(zuo)用，更不會出(chu)管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)中現(xian)物(wu)料碳(tan)化(hua)現(xian)象，管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)運行(xing)無(wu)噪音(yin)，無(wu)污染，管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)的使用壽命(ming)長（30000小時以(yi)上），管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)熱(re)(re)器(qi)的節能顯(xian)著（28%以(yi)上）。
