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)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)另一(yi)種模式是遠紅外電加(jia)(jia)(jia)熱(re)(re)(re)裝置。即(ji)管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)中(zhong)(zhong)(zhong)的(de)(de)(de)內(nei)(nei)部系統中(zhong)(zhong)(zhong)的(de)(de)(de)電加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)包裹住(zhu)管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)中(zhong)(zhong)(zhong)反應(ying)釜底(di)部及管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)中(zhong)(zhong)(zhong)下(xia)部位進行加(jia)(jia)(jia)熱(re)(re)(re)。管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)遠紅外電加(jia)(jia)(jia)熱(re)(re)(re)裝置具有管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)內(nei)(nei)部系統的(de)(de)(de)加(jia)(jia)(jia)熱(re)(re)(re)面(mian)積大，管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)升溫(wen)平穩而快，管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)放熱(re)(re)(re)均勻，管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)溫(wen)度控制方便(bian)，管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)可(ke)上、中(zhong)(zhong)(zhong)、下(xia)分段控制，管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)釜內(nei)(nei)釜壁溫(wen)度易控制，管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)對釜內(nei)(nei)物燃料(liao)無(wu)任何副作用，更不(bu)會出管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)中(zhong)(zhong)(zhong)現(xian)物料(liao)碳化現(xian)象，管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)運行無(wu)噪音，無(wu)污染，管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)使用壽命長（30000小時以(yi)上），管(guan)(guan)(guan)(guan)(guan)道(dao)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)節能顯著（28%以(yi)上）。
