天然氣燒嘴的概念及分類燃料為天然氣的燃燒裝置稱為天然氣燒嘴，工業(yè)窯爐和化工加熱裝置中對(duì)天然氣燃燒裝置的習(xí)慣叫法，也有部分習(xí)慣稱之為天然氣燃燒器。產(chǎn)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(zhǎng)焰燒嘴，火焰較長(zhǎng)，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(nèi)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(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。它的主要缺點(diǎn)是：（1）霧化能量利用率低（2）霧化氣用量大（3）對(duì)于高粘度的重柴油、重渣油、水煤漿不能高效燃燒的要求
