style="text-indent:25px">產品分類：按照燒嘴前天然氣的壓力高低：低壓天然氣燒嘴：天然氣壓力在5kpa以下。高中壓天然氣燒嘴：天然氣壓力在5kpa以上。按照火焰的形狀類型：直焰燒嘴：又稱長焰燒嘴，火焰較長，一般窯爐上采用較多。短焰燒嘴:火焰短而有剛性。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。按照空氣供給方式分類：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，一般燒嘴功率較小。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。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。</p><p

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。工藝應用燒嘴，一般功率較小，沒有特定的型號，可以根據實際的工藝來開發(fā)出來的燒嘴，并且屬于損耗件。冶煉燒嘴圖片</p><p style="text-indent:25px">燃料為天然氣的燃燒裝置稱為天然氣燒嘴。蘇州燃氣燒嘴哪家好</p><p style="text-indent:25px">天然氣燒嘴的類型很多，只能按照部分共性進行分類。 (1)按一次空氣分類 ① 擴散式燒嘴: 一次空氣系數(shù)為0，燃燒空氣全部依靠二次空氣。 ② 大氣式燒嘴:一次空氣系數(shù)在0.2～0.8之間，剩余的依靠二次空氣。 ③ 完全預混燒嘴:一次空氣系數(shù)等于過剩空氣系數(shù)，約為1.05～1.15，燃燒不需要二次空氣。 (2)按空氣供給方法分類 ① 引射式燒嘴：空氣靠燃氣的引射作用吸入，或空氣引射燃氣。 ② 鼓風式燒嘴：用鼓風機將空氣送入燃燒設備。 ③ 自然引風式燒嘴：靠爐膛的負壓將空氣吸入燃燒系統(tǒng)。 (3)按燃氣壓力分類 ① 低壓燒嘴：燃氣壓力小于5000Pa。 ② 高(中)壓燒嘴：燃氣壓力在5000～300000Pa之間。 (4)按燃氣熱值分類 ① 低熱值燒嘴。 ② 高熱值燒嘴。 (5)按燃氣與空氣混合形成地點分類 ① 外部混合式燒嘴：燃氣與空氣的混合在燃燒室外。 ② 內部混合式燒嘴：燃氣與空氣在燃燒室內混合。蘇州燃氣燒嘴哪家好</p><p
