高爐煤氣是冶金聯(lián)合企業(yè)主要的副產(chǎn)廢氣，經(jīng)過凈化處理，是一種輸送和使用方便、燃燒后又無需排渣和除塵的質(zhì)量環(huán)保能源，我國大部分的冶金企業(yè)都采取了煤氣回收利用措施，但隨著高爐原料條件的改善和裝備水平的提高，高爐煤氣的發(fā)熱值越來越低（大型高爐煤氣熱值已降到3140kJ/m3，中小高爐分別降到3340~3550kJ/m3和3760~3970kJ/m3），因此如何有效提高高爐風(fēng)溫成為一個重要課題。高爐熱風(fēng)爐采用空氣、煤氣雙預(yù)熱是提高風(fēng)溫的有效途徑。燃燒單一高爐煤氣（熱值3369kJ/m3），不預(yù)熱時，其理論燃燒溫度只有1280℃；只預(yù)熱空氣到250℃時，其理論燃燒溫度提高到1330℃；而空氣、煤氣雙預(yù)熱到170℃時，能提高到1380℃。u工藝：利用300℃左右的煙氣分別預(yù)熱助燃空氣、高爐煤氣至約150℃。板式空氣預(yù)熱器是一種冶金行業(yè)經(jīng)常使用的節(jié)能、環(huán)保設(shè)備。陜西空氣預(yù)熱器加盟</p><p
