按照燒嘴前天然氣的壓力高低： </p> <p> 低壓天然氣燒嘴：天然氣壓力在5kpa以下。 </p> <p> 高中壓天然氣燒嘴：天然氣壓力在5kpa以上。 </p> <p> 按照火焰的形狀類型： </p> <p> 直焰燒嘴：又稱長焰燒嘴，火焰較長，一般窯爐上采用較多。 </p> <p> 短焰燒嘴:火焰短而有剛性。 </p> <p> 平焰燒嘴：火焰緊貼爐墻或是爐頂內(nèi)部向四周均勻伸展的圓盤形狀噴出。 </p> <p> 按照空氣供給方式分類： </p> <p> 自吸式燒嘴：燒嘴不需要借助外力配風(fēng)，自身文丘里式結(jié)構(gòu)，可吸入外界空氣，一般燒嘴功率較小。 </p> <p> 配風(fēng)式燒嘴：依靠鼓風(fēng)機(jī)強(qiáng)制配助燃風(fēng)，風(fēng)機(jī)通常為高壓離心風(fēng)機(jī)。 </p><p>

燒嘴正常的運(yùn)行，對產(chǎn)品質(zhì)量高低和企業(yè)運(yùn)行成本都有很大影響。原則上講在對燃?xì)夤I(yè)爐設(shè)計時，針對燃?xì)鉄斓南到y(tǒng)設(shè)計非常嚴(yán)格，新建造的燃?xì)鉅t會有專業(yè)設(shè)計者對燃燒系統(tǒng)進(jìn)行論證，模擬實(shí)驗(yàn)，但對于從燃煤爐窯改造成燃?xì)鉅t窯的燃燒系統(tǒng)就很少有專業(yè)人員進(jìn)行計算，而只是采用所謂的經(jīng)驗(yàn)數(shù)據(jù)，但這樣的在很大程度上會導(dǎo)致燃料浪費(fèi)嚴(yán)重，企業(yè)成本增加，甚至失去市場競爭力。當(dāng)煤氣流速等于空氣流速時，著火燃燒點(diǎn)就會在距燃燒器出口的定距離處燃燒，火焰剛直有力。</p><div
