style="text-indent:25px">工業(yè)爐以單位時(shí)間單位爐底面積計(jì)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(fù)荷生產(chǎn)，盡量提高爐子生產(chǎn)率，同時(shí)對(duì)燃燒裝置實(shí)行燃料與助燃空氣的自動(dòng)比例調(diào)節(jié)，以防止空氣量過(guò)?；虿蛔?。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。金屬或物料加熱時(shí)吸收的熱量與供入爐內(nèi)的熱量之比，稱為爐子熱效率。連續(xù)式爐比間斷式爐的熱效率高，因?yàn)檫B續(xù)式爐的生產(chǎn)率高，而且是不間斷工作的，爐子熱制度處于穩(wěn)定狀態(tài)，沒有周期性的爐墻蓄熱損失，還由于爐膛內(nèi)部有一個(gè)預(yù)熱爐料的區(qū)段，煙氣部分余熱為入爐的冷工件所吸收，降低了離爐煙氣的溫度。</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(dān)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(fù)雜。在化工裝置提高出力時(shí)，井式爐往往是制的出力的環(huán)節(jié)。井式爐的工藝過(guò)程由熱力學(xué)一定律來(lái)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(xué)第二定律來(lái)評(píng)估井式爐，那么應(yīng)該用煙（或稱有效能）放率呈長(zhǎng)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(jìn)一步提高。化工流程和下業(yè)爐都受到原料和燃料種類的影響。在工業(yè)爐的燃?xì)?、燃油、燃煤等燃燒過(guò)程中，空氣量不足則會(huì)出現(xiàn)不能充分燃燒的狀況。</p><div
