</p><p style="text-indent:25px">用其它介質(zhì)加熱若工藝要求必須在高溫下操作或欲避免采用高壓的加熱系統(tǒng)時(shí)，可用其它介質(zhì)來(lái)代替水和蒸汽，如礦物油(275～300℃)、聯(lián)苯醚混合劑(沸點(diǎn)258℃)、熔鹽(140～540℃)、液態(tài)鉛(熔點(diǎn)327℃)等。4、電加熱將電阻絲纏繞在反應(yīng)釜筒體的絕緣層上，或安裝在離反應(yīng)釜若干距離的特設(shè)絕緣體上，因此，在電阻絲與反應(yīng)釜體之間形成了不大的空間間隙。**種方法獲得高溫均需在釜體上增設(shè)夾套，由于溫度變化的幅度大，使釜的夾套及殼體承受溫度變化而產(chǎn)生溫差壓力。采用電加熱時(shí)，設(shè)備較輕便簡(jiǎn)單，溫度較易調(diào)節(jié)，而且不用泵、爐子、煙囪等設(shè)施，開(kāi)動(dòng)也非常簡(jiǎn)單，危險(xiǎn)性不高，成本費(fèi)用較低，但操作費(fèi)用較其它加熱方法高，熱效率在85%以下，因此適用于加熱溫度在400℃以下和電能價(jià)格較低的地方。</p><div
