1.1.1 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(jié)構(gòu)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(jié)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(zhuǎn)化為霧化能量，常見機械霧化燒嘴是轉(zhuǎn)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(zhuǎn)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(zhuǎn)。氣液兩相產(chǎn)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(diào)節(jié)范圍廣、霧化性能好。工業(yè)燒嘴哪些品牌自吸式燒嘴：燒嘴不需要借助外力配風，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><div

自身預熱燒嘴又稱換熱式燒嘴，它是將燃氣入口、助燃風入口、點火電極、燃燒室、換熱器和排煙口組合成一個整體的燃燒裝置。自身預熱式燒嘴的使用替代了煙道熱交換器，無需額外占地面積且熱利用效率更高。但自身預熱式燒嘴由于其應用的特殊性和結(jié)構(gòu)復雜性，在使用過程中有很多需要注意的地方，掌握了這些注意事項，會在使用過程中避免很多不必要的麻煩。明火直接加熱應用中要安裝煙氣導流套：在間接加熱應用時，煙氣可以通過換熱器與輻射管的間隙排出爐膛，從而實現(xiàn)熱量的交換。在明火加熱時，我們也需要加裝煙氣導流套來強制煙氣在這個環(huán)形間隙中通過，實現(xiàn)很大程度的熱交換。換熱器與輻射管縫隙較大時安裝煙氣導流套：跟上一條相似，在輻射管直徑較大而燒嘴功率較小的情況下，由于換熱器與輻射管直徑的縫隙過大會造成煙氣不能貼近換熱器，影響換熱效率。所以需要加裝尺寸合適的煙氣導流套。 </p>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慣叫法，也有部分習慣稱之為天然氣燃燒器。<p>產(chǎn)品分類：<p>按照燒嘴前天然氣的壓力高低：<p>低壓天然氣燒嘴：天然氣壓力在5kpa以下。<p>高中壓天然氣燒嘴：天然氣壓力在5kpa以上。<p><br/><p>按照火焰的形狀類型：<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>短焰燒嘴:火焰短而有剛性。<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><br/><p>按照空氣供給方式分類：<p>自吸式燒嘴：燒嘴不需要借助外力配風，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>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。直焰燒嘴：又稱長焰燒嘴，火焰較長，一般窯爐上采用較多。<div

1.合理的空燃氣比例是點火的必要條件，這就要求我們要提供合理的空燃氣壓力。 2.在確定有燃氣的情況下，空氣壓力太大或者太小都有可能無法點燃。 3.不同品牌不同型號的燒嘴所要求的空燃氣壓力有所不同，此時要查看相關技術(shù)資料或咨詢廠家。 4.一般情況下空燃氣壓力越小點火成功率越高。 5.配備空燃比例閥的管路系統(tǒng)，在點火時由于空氣壓力低，往往空燃比例閥沒有被頂開，這時我們要調(diào)節(jié)比例閥彈簧，使比例閥開啟一定的開度，允許一小股燃氣過去參與點火。點火燒嘴損壞的原因：當燃料中焦爐煤氣配比的增多，燃燒得到了強化，燃燒器局部溫度升高，點火燒嘴被燒壞；廣東點火燒嘴怎么樣</p><p style="text-indent:25px">部分（或全部）燒嘴可通過某些方式（包括PWM技術(shù)）調(diào)節(jié)燃燒輸出的熱量來控制輸出溫度。廣東點火燒嘴怎么樣</p><p style="text-indent:25px"> 燒嘴的特點是燃料在燒嘴的燃燒室內(nèi)完全燃燒后產(chǎn)生的熱氣在高溫下急劇膨脹,在噴口形成高速氣流,當燒嘴在滿負荷時(額定功率),噴出的氣流速度較高,為了充分利用高速燒嘴的這一特性,提出了對燒嘴實現(xiàn)大小火控制的要求。對燒嘴實現(xiàn)連續(xù)調(diào)節(jié)時,是調(diào)節(jié)進入燒嘴的燃料的流量,從而達到調(diào)節(jié)燒嘴燃燒功率的目的,進入燒嘴的燃料量越大 ,燒嘴輸出的熱功率也就越高,反之就越小,燃料的流量對應燒嘴的輸出功率.我們?nèi)挝粫r間內(nèi)進入燒嘴燃料的平均流量,對其進行較大和較小兩段分配,使其平均流量和燒嘴在這段時間內(nèi)所需要的能力相符合,從而同樣達到了對燒嘴燃燒功率的調(diào)節(jié)。廣東點火燒嘴怎么樣</p><p
