<p> 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，江蘇碳化硅燒嘴哪家好。 </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，江蘇碳化硅燒嘴哪家好。 </p> <p> 平焰燒嘴：火焰緊貼爐墻或是爐頂內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，自身文丘里式結構，可吸入外界空氣，江蘇碳化硅燒嘴哪家好，一般燒嘴功率較小。 </p> <p> 配風式燒嘴：依靠鼓風機強制配助燃風，風機通常為高壓離心風機。燃燒所需要的空氣預先和天然氣混合，一般多用在無焰燃燒類型的燒嘴上。江蘇碳化硅燒嘴哪家好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇碳化硅燒嘴哪家好,天燃氣燒嘴"

燒嘴正常的運行，對產品質量高低和企業(yè)運行成本都有很大影響。原則上講在對燃氣工業(yè)爐設計時，針對燃氣燒嘴的系統(tǒng)設計非常嚴格，新建造的燃氣爐會有專業(yè)設計者對燃燒系統(tǒng)進行論證，模擬實驗，但對于從燃煤爐窯改造成燃氣爐窯的燃燒系統(tǒng)就很少有專業(yè)人員進行計算，而只是采用所謂的經驗數(shù)據(jù)，但這樣的在很大程度上會導致燃料浪費嚴重，企業(yè)成本增加，甚至失去市場競爭力。廣東冶煉燒嘴廠家哪家便宜燒嘴可分為蓄熱式燒嘴、輻射管燒嘴、可調溫燒嘴、低氮燒嘴等多種新型節(jié)能燒嘴。</p><div

style="text-indent:25px">燒嘴按照用途來分，有可以分為工業(yè)應用燒嘴，商業(yè)應用燒嘴，工藝應用燒嘴。工業(yè)應用燒嘴以及商業(yè)應用燒嘴一般功率較大，一般屬于固定設備。工藝應用燒嘴，一般功率較小，沒有特定的型號，可以根據(jù)實際的工藝來開發(fā)出來的燒嘴，并且屬于損耗件。燒嘴按點火方式分為兩種：一種是自動點火，點火方式通過電極發(fā)出高壓點燃可燃氣體；一種是人工點火。點火方式是用明火點燃可燃氣體。自動點火適用于相對純凈氣體；人工點火適用于純凈可燃氣體、較臟可燃氣體。工藝燒嘴普遍應用于產品成型以后的工藝處理，如玻璃器皿成型后的拋光，切割，燒口，應力處理等，塑料件表面噴涂之前的火焰處理，以增強塑料件表面的張力/親水性，增強噴漆的效果。</p><p style="text-indent:25px"> 原燒嘴長度較短，沒有伸出保溫墻外，使用一段時間后，燒嘴出口的壁面上結滿積碳，很難清理，影響燃燒效果；且原燒嘴未設觀察孔，操作工無法探知燒嘴內部是否積碳和燃燒狀況，故要求操作工每天每個燒嘴都要清理一次，如按10臺爐塔來算，每天要清理180個燒嘴，工作強度大。經過將主燒嘴加長、增設觀察孔等改進措施后，清理變得更加有針對性，不需要逐一盲目清理，勞動強度大降低；并使積碳清理裝置推桿與燒嘴徹底分離，杜絕了因推桿過長阻擋工作通道而造成的安全隱患；另外，通過觀察孔還可以觀察到天然氣的燃燒狀況，判斷爐內天然氣燃燒是否過剩并加以調整，從而起到節(jié)能降耗作用。燒嘴不需要借助外力配風，自身文丘里式結構，可吸入外界空氣，一般燒嘴功率較小。</p><div

天然氣燒嘴按照空燃混合方式：擴散式燒嘴：燃燒所需要的空氣不預先和天然氣混合。大氣式燒嘴：又稱半預混合天然氣燒嘴。燃燒所需要的空氣部分與天然氣混合。完全預混合式燒嘴：燃燒所需要的空氣預先和天然氣混合，一般多用在無焰燃燒類型的燒嘴上。特殊功能分類：可分為蓄熱式燒嘴、輻射管燒嘴、可調溫燒嘴、低氮燒嘴等多種新型節(jié)能燒嘴。用途:天然氣燒嘴是工業(yè)窯爐上常用的燃燒裝置，天然氣燒嘴性能的好壞將很大程度上影響產品的質量，合理高效的天然氣燒嘴應該能滿足窯爐的燃燒、加熱和產品工藝所滿要求的條件。燒嘴常識:天然氣的燃燒一般分為三個過程：燃氣和空氣的混合；混合氣體的升溫和著火；混合氣體的燃燒。火焰穩(wěn)定的條件是，火焰?zhèn)鞑ニ俣群涂扇細怏w混合物的流動速度大小相等方向相反。穩(wěn)定的燃燒：燃氣和空氣混合速度超過火焰?zhèn)鞑ニ俣葘е禄鹧骐x開穩(wěn)定點。燒嘴的回火：燃氣和空氣混合速度小于火焰?zhèn)鞑ニ俣?，火焰向燒嘴內部噴射。燒嘴的脫火和回火都不是理想燒嘴的燃燒狀態(tài)，燒嘴多采用穩(wěn)焰盤結構來達到良好狀態(tài)。燒嘴的回火：燃氣和空氣混合速度小于火焰?zhèn)鞑ニ俣?，火焰向燒嘴內部噴射。廣東冶煉燒嘴廠家哪家便宜</p><p

壓力霧化燒嘴壓力霧化燒嘴是靠燃油自身的壓力轉化為噴射動能，通過液膜或液柱受空氣的剪切擾動而使燃油霧化。這種燒嘴的優(yōu)點是結構簡單、運行成本低。缺點是當負荷變小時霧化顆粒度及平均尺寸迅速增加燃燒效率降低且小流量燒嘴易堵賽和結焦。 1.1.2 機械霧化燒嘴機械霧化燒嘴是將燃油的機械能轉化為霧化能量，常見機械霧化燒嘴是轉杯式霧化燒嘴。此類燒嘴對機械能要求較高，一般要求非常高的轉速才能霧化所需的剪切力。 1.1.3 氣動霧化燒嘴氣動霧化燒嘴是利用空氣或蒸氣的高速運動對液膜或液柱進行撞擊、剪切、旋轉。氣液兩相產生相對高的相對速度來實現(xiàn)破碎霧化。氣動霧化燒嘴的優(yōu)點是調節(jié)范圍廣、霧化性能好。江蘇碳化硅燒嘴哪家好</p></p><br /><p>文章來源地址:
