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)爐的燃料來源廣，價格低，便于因地制宜采取不同的結(jié)構(gòu)，有利于降低生產(chǎn)費用，但火焰爐難于實現(xiàn)精確控制，對環(huán)境污染嚴重，熱效率較低。電爐的特點是爐溫均勻和便于實現(xiàn)自動控制，加熱質(zhì)量好。按能量轉(zhuǎn)換方式，電爐又可分為電阻爐、感應(yīng)爐和電弧爐。以單位時間單位爐底面積計算的爐子加熱能力稱為爐子生產(chǎn)率。爐子升溫速度越快、爐子裝載量越大，則爐子生產(chǎn)率越高。在一般情況下，爐子生產(chǎn)率越高，則加熱每千克物料的單位熱量消耗也越低。因此，為了降低能源消耗，應(yīng)該滿負荷生產(chǎn)，盡量提高爐子生產(chǎn)率，同時對燃燒裝置實行燃料與助燃空氣的自動比例調(diào)節(jié)，以防止空氣量過剩或不足。此外，還要減少爐墻蓄熱和散熱損失、水冷構(gòu)件熱損失、各種開口的輻射熱損失、離爐煙氣帶走的熱損失等。工業(yè)爐具備要求：爐溫、氣氛易于控制，產(chǎn)品質(zhì)量好。</p><div
