1、外輸蒸汽管道：對帶有鍋筒或汽包裝置的爐型來說，經(jīng)汽包汽水分離后，其外輸蒸汽管道通常表壓≥0.4MPa，管徑≥80mm，介質(zhì)參數(shù)符合特種設(shè)備中的壓力管道定義，故屬于壓力管道。 2、吹掃放散系統(tǒng)來源管道：介質(zhì)通常為氮氣，吹掃點前來源管道通常表壓≥0.3MPa，管徑≥50mm。介質(zhì)參數(shù)符合特種設(shè)備中的壓力管道定義，故屬于壓力管道。 3、儀表用氣管道：介質(zhì)通常為壓縮空氣，北京　Nabertherm工業(yè)爐熱處理設(shè)備，一般情況下表壓≥0.3MPa，管徑≥50mm。

style="text-indent:25px">由工業(yè)爐（窯）的定義、分類及結(jié)構(gòu)章節(jié)可知，鍋爐本質(zhì)上也屬于工業(yè)爐窯，從結(jié)構(gòu)上講，其即有“鍋”的特殊結(jié)構(gòu)，也有“爐”的通用結(jié)構(gòu)，因此，鍋爐安全技術(shù)對于大多數(shù)工業(yè)爐來講，都有一定的通用（爐結(jié)構(gòu)部分）借鑒作用。另外，許多其它類型的工業(yè)爐，如軋鋼加熱爐，也同時具有“鍋”和“爐”兩個部分的結(jié)構(gòu)，只不過鍋爐產(chǎn)蒸汽是其主要功能，而加熱爐產(chǎn)蒸是其附屬功能，（一個是專業(yè)產(chǎn)汽，一個是業(yè)余產(chǎn)汽，所以加熱爐也不屬于特種設(shè)備），加熱爐的“鍋”結(jié)構(gòu)部分通常稱為汽化冷卻系統(tǒng)，其汽包的安全運行規(guī)則原理與鍋爐的鍋筒部分幾乎完全同理，故鍋爐的安全技術(shù)對此類型爐窯則具有完全相似的借鑒作用。</p><p style="text-indent:25px">工業(yè)爐是整套化工裝置中較龐大的設(shè)備之一，常在化工流程中擔任照料轉(zhuǎn)化這一主要工序。工業(yè)反應(yīng)爐常，結(jié)構(gòu)復雜。在化工裝置提高出力時，井式爐往往是制的出力的環(huán)節(jié)。井式爐的工藝過程由熱力學一定律來看是可以做到高效率的;但是老式工業(yè)電爐一般煙氣廢熱沒有充分利用，熱效率只有60%左右。在新式工業(yè)電爐巾熱效率舊以提高到80-90%。如果用熱力學第二定律來評估井式爐，那么應(yīng)該用煙（或稱有效能）放率呈長衡景。井式爐的煙效率很低，一般不大于50% 由上述可以看出，工業(yè)電爐節(jié)能潛力很人，所以化工裝置的能源利用率完全可以在工業(yè)爐上采取技術(shù)措施以進一步提高?；ち鞒毯拖聵I(yè)爐都受到原料和燃料種類的影響。工業(yè)爐內(nèi)溫度均勻度狀態(tài)，主要受電熱元件布置，爐門的密封和保溫狀態(tài)的影響，通常爐膛前溫度較低。</p><div

style="text-indent:25px">工業(yè)爐在其生產(chǎn)過程中經(jīng)常會涉及熔煉、干燥、烘烤、加還化學反應(yīng)等加熱的工序。而工業(yè)爐窯就是用于這些工序的加熱設(shè)備。而為這些設(shè)備提供熱源的燃料主要有氣體燃料、液體燃料、固體燃料和電。使用這些加熱設(shè)備，容易發(fā)生燒傷、觸電事故。如果使用氣體、液體燃料，一旦發(fā)生泄漏或溢出，亦可能構(gòu)成火災(zāi)、的危險。工業(yè)爐使用時爐門升降機構(gòu)必須完好，鋼絲繩斷絲不準超過規(guī)定值。重錘配置適當，外露傳動部分應(yīng)設(shè)防護罩。如果是水冷卻的爐門，還要保證管道暢通，冬季管路不冰凍。爐門要有限位裝置，進出爐時，要有切斷電源的聯(lián)鎖裝置，鋼絲繩在節(jié)距內(nèi)斷絲數(shù)不得超過10%，平衡爐門的重錘懸掛應(yīng)可靠。要求外露傳動部分的防護裝置應(yīng)保持正確的安裝位置，結(jié)構(gòu)合理。爐車鋼絲繩滑輪應(yīng)完整無損。爐窯上所有滑輪、鏈輪結(jié)構(gòu)完好，無缺損，轉(zhuǎn)動靈活。工業(yè)爐的操作方便程度，以及安全性指標等。北京　Nabertherm工業(yè)爐熱處理設(shè)備</p><p
