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)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)另(ling)一種模式是遠紅外(wai)電加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)裝置。即管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中(zhong)(zhong)(zhong)的(de)(de)內部(bu)(bu)系統中(zhong)(zhong)(zhong)的(de)(de)電加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)包裹住管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中(zhong)(zhong)(zhong)反應釜(fu)底(di)部(bu)(bu)及管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)中(zhong)(zhong)(zhong)下(xia)部(bu)(bu)位進行加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)。管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)遠紅外(wai)電加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)裝置具有(you)管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)內部(bu)(bu)系統的(de)(de)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)面(mian)積(ji)大，管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)升溫(wen)(wen)平穩而(er)快(kuai)，管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)放熱(re)(re)(re)(re)(re)均勻(yun)，管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)溫(wen)(wen)度控(kong)(kong)制方便，管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)可上、中(zhong)(zhong)(zhong)、下(xia)分段控(kong)(kong)制，管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)釜(fu)內釜(fu)壁溫(wen)(wen)度易控(kong)(kong)制，管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)對釜(fu)內物(wu)燃料(liao)無(wu)任(ren)何(he)副作(zuo)用，更不會出(chu)管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)中(zhong)(zhong)(zhong)現(xian)物(wu)料(liao)碳化現(xian)象，管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)運行無(wu)噪音(yin)，無(wu)污染，管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)使用壽命長(chang)（30000小時以上），管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)節能(neng)顯著（28%以上）。
