style="text-indent:25px">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(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 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、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。燒嘴廠商它的優(yōu)點(diǎn)是結(jié)構(gòu)簡單氣體流動(dòng)的阻力小，因此所要求的煤氣與空氣的壓力比其他燒嘴都低，一般只要784~1470Pa。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="燒嘴廠商,天燃?xì)鉄? src="https://tyunfile.71360.com/UploadFile/wds2020/637311307973408203/2278180.png"></div><p style="text-indent:25px">燃油燒嘴 1.1 按霧化方法分類 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(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(duì)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(duì)液膜或液柱進(jìn)行撞擊、剪切、旋轉(zhuǎn)。氣液兩相產(chǎn)生相對(duì)高的相對(duì)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。</p><p> 使用I型（一字型）輻射管要安裝陶瓷火焰內(nèi)管，讓火焰形成循環(huán)通道：一字型輻射管不同于P型、雙P型輻射管，要想形成煙氣的循環(huán)流動(dòng)，必須在管內(nèi)預(yù)先塞入耐高溫陶瓷內(nèi)管。從燒嘴出來的高溫?zé)煔庀冗M(jìn)入陶瓷管內(nèi)側(cè)，當(dāng)煙氣走到輻射管末端后會(huì)從陶瓷管外側(cè)返回，少量煙氣會(huì)二次參與燃燒，大部分從燒嘴換熱器外側(cè)排出，形成循環(huán)流動(dòng)。不同的爐溫選擇不同的換熱器材質(zhì)：自身預(yù)熱式燒嘴換熱器一般有三種材質(zhì)，要根據(jù)不同分爐溫選擇相應(yīng)的材質(zhì)。分別是：BSREC..M——金屬翅片BSREC..C——碳化硅波紋BSREC..FTR——金屬光面不同的燃?xì)鉄祛~定功率不一樣:燒嘴的額定功率一般是以天然氣為標(biāo)準(zhǔn)計(jì)算的，在使用焦?fàn)t煤氣和其他低熱值燃?xì)獾那闆r下，額定功率肯定是要下降的。具體按下面的比例計(jì)算：焦?fàn)t煤氣：額定功率的80%。低熱值煤氣：額定功率的65%。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><div

用燒嘴。工業(yè)應(yīng)用燒嘴以及商業(yè)應(yīng)用燒嘴一般功率較大，一般屬于固定設(shè)備。工藝應(yīng)用燒嘴，一般功率較小，沒有特定的型號(hào)，可以根據(jù)實(shí)際的工藝來開發(fā)出來的燒嘴，并且屬于損耗件。燒嘴按點(diǎn)火方式分為兩種：一種是自動(dòng)點(diǎn)火，點(diǎn)火方式通過電極發(fā)出高壓點(diǎn)燃可燃?xì)怏w；一種是人工點(diǎn)火。點(diǎn)火方式是用明火點(diǎn)燃可燃?xì)怏w。自動(dòng)點(diǎn)火適用于相對(duì)純凈氣體；人工點(diǎn)火適用于純凈可燃?xì)怏w、較臟可燃?xì)怏w。工藝燒嘴普遍應(yīng)用于產(chǎn)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(yīng)力處理等，塑料件表面噴涂之前的火焰處理，以增強(qiáng)塑料件表面的張力/親水性，增強(qiáng)噴漆的效果。燒嘴廠商</p><p
