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，北京冶煉燒嘴哪些品牌。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，北京冶煉燒嘴哪些品牌。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）對于高粘度的重柴油、重渣油、水煤漿不能高效燃燒的要求 1.1.4 氣泡霧化燒嘴氣泡霧化在國際上被稱為第三代霧化技術(shù)，這種燒嘴是在特殊結(jié)構(gòu)的通道中注入壓縮空氣或蒸氣，使之在燃油中形成數(shù)量巨大的氣泡，氣泡經(jīng)運(yùn)動(dòng)、變形，北京冶煉燒嘴哪些品牌、加速等一系列過程后至燒嘴出口處破碎，從而形成液滴非常小、尺寸均勻度大的液霧。燒嘴也可以叫燃燒器，但不同于小型鍋爐上用的一體化燃燒器。北京冶煉燒嘴哪些品牌</p><div

壓力霧化燒嘴壓力霧化燒嘴是靠燃油自身的壓力轉(zhuǎn)化為噴射動(dòng)能，通過液膜或液柱受空氣的剪切擾動(dòng)而使燃油霧化。這種燒嘴的優(yōu)點(diǎn)是結(jié)構(gòu)簡單、運(yùn)行成本低。缺點(diǎn)是當(dāng)負(fù)荷變小時(shí)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(jié)焦。 1.1.2 機(jī)械霧化燒嘴機(jī)械霧化燒嘴是將燃油的機(jī)械能轉(zhuǎn)化為霧化能量，常見機(jī)械霧化燒嘴是轉(zhuǎn)杯式霧化燒嘴。此類燒嘴對機(jī)械能要求較高，一般要求非常高的轉(zhuǎn)速才能霧化所需的剪切力。 1.1.3 氣動(dòng)霧化燒嘴氣動(dòng)霧化燒嘴是利用空氣或蒸氣的高速運(yùn)動(dòng)對液膜或液柱進(jìn)行撞擊、剪切、旋轉(zhuǎn)。氣液兩相產(chǎn)生相對高的相對速度來實(shí)現(xiàn)破碎霧化。氣動(dòng)霧化燒嘴的優(yōu)點(diǎn)是調(diào)節(jié)范圍廣、霧化性能好。定制燒嘴廠商燒嘴（英文名稱：burner）是工業(yè)燃料爐上用的燃燒裝置的俗稱。</p><div
