單段煤氣發(fā)生爐工藝由煤氣爐主機(jī)和落灰斗、平底旋風(fēng)除塵器等設(shè)備組成,適用于一般性加熱場(chǎng)所。
單段煤氣發(fā)生爐性能特點(diǎn):
1.工藝簡(jiǎn)單,占地少,投資小,操作簡(jiǎn)單。
2.機(jī)械上煤,濕式出渣,無二次污染。
3.煤氣出口溫度400-550℃,熱能利用率*。
單段煤氣發(fā)生爐適用范圍:
化工加熱,熱處理爐,鍋爐煤氣化改造,耐火材料行業(yè)
單段環(huán)保煤氣發(fā)生爐工作原理:
固體燃料煤炭在汽化物的媒介下氣化生成可燃?xì)怏w,由于汽化物媒體介質(zhì)為混合物而生成可燃?xì)怏w為混合形式,故稱混合煤氣。生成的熱煤氣經(jīng)過初級(jí)除塵后由輸送管道向用氣熱加工爐噴嘴噴發(fā)燃燒,由爐體外圍熱風(fēng)道輸出的余熱風(fēng)對(duì)噴嘴進(jìn)行增氧助燃,產(chǎn)生高溫對(duì)熱工爐進(jìn)行加熱,達(dá)到熱工爐所需的熱值指標(biāo),由于爐內(nèi)燃燒為氣體,所以溫度相當(dāng)均勻。它廣泛適用于軋鋼爐、退火爐、鍛造爐、鋼管爐、玻璃爐、熔鋁爐、銅材爐、建陶爐等各種熱工爐所需溫度范圍內(nèi)的各種爐形。
