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)熱(re)(re)(re)器(qi)(qi)(qi)的(de)另一種模式是遠紅外電加(jia)(jia)(jia)熱(re)(re)(re)裝置(zhi)。即管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)中(zhong)的(de)內(nei)部(bu)系(xi)統(tong)中(zhong)的(de)電加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)包(bao)裹住管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)中(zhong)反(fan)應釜(fu)底(di)部(bu)及管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)中(zhong)下(xia)部(bu)位進(jin)行加(jia)(jia)(jia)熱(re)(re)(re)。管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)遠紅外電加(jia)(jia)(jia)熱(re)(re)(re)裝置(zhi)具有管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)內(nei)部(bu)系(xi)統(tong)的(de)加(jia)(jia)(jia)熱(re)(re)(re)面(mian)積大，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)升(sheng)溫平(ping)穩而快，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)放(fang)熱(re)(re)(re)均勻，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)溫度(du)(du)控(kong)制方便，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)可上(shang)、中(zhong)、下(xia)分(fen)段控(kong)制，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)釜(fu)內(nei)釜(fu)壁(bi)溫度(du)(du)易控(kong)制，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)對釜(fu)內(nei)物(wu)燃料無任(ren)何副作(zuo)用，更不會出管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)中(zhong)現物(wu)料碳化現象(xiang)，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)運(yun)行無噪(zao)音，無污染，管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)使(shi)用壽命長(chang)（30000小(xiao)時(shi)以上(shang)），管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)(qi)的(de)節能(neng)顯著（28%以上(shang)）。
