燃氣爐窯新建或是燃料改造中，中威爐業(yè)認為要從多方面進行考慮：燃氣燒嘴的選型、空氣過剩系數(shù)的設(shè)定、燃氣管路的設(shè)計等。首先燒嘴的選型是**基本的一項。當確定燃氣種類后，下一步要確定的是燒嘴的類型和功率的大小，這里不再詳細介紹，以適合自己爐窯為準，并不是高級的復(fù)雜就是**適合的。其次燃燒系統(tǒng)中空氣過剩系數(shù)的確定。這里**主要牽涉到風機的選擇，一般以高壓離心風機選用較多。對風機的風量和風壓的選擇非常重要?？諝膺^剩系數(shù)過大或是過小火焰都將不能正常傳播。燃燒過程中火焰不可避免的要向四周環(huán)境散失一部分熱量，當混合物的理論溫度升高時，火焰鋒面可以達到理論燃燒溫度，此時散熱可以忽略不計。當過剩系數(shù)過大或是過小時燃氣的濃度過高或過低，燃燒產(chǎn)生的熱本身就太少了，再加之存在散熱，結(jié)果火焰鋒面的實際燃燒溫度就更低了，火焰鋒面內(nèi)的燃燒化學熱反應(yīng)就難以維持，火焰?zhèn)鞑バЧ麡O差。廣東冶煉燒嘴價錢多少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。</p><div

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，必須在管內(nèi)預(yù)先塞入耐高溫陶瓷內(nèi)管。從燒嘴出來的高溫煙氣先進入陶瓷管內(nèi)側(cè)，當煙氣走到輻射管末端后會從陶瓷管外側(cè)返回，少量煙氣會二次參與燃燒，大部分從燒嘴換熱器外側(cè)排出，形成循環(huán)流動。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——金屬光面不同的燃氣燒嘴額定功率不一樣:燒嘴的額定功率一般是以天然氣為標準計算的，在使用焦爐煤氣和其他低熱值燃氣的情況下，額定功率肯定是要下降的。具體按下面的比例計算：焦爐煤氣：額定功率的80%。低熱值煤氣：額定功率的65%。 </p><p> 燃氣工業(yè)爐在工業(yè)生產(chǎn)中占據(jù)重要地位，燃氣燒嘴作為工業(yè)爐窯中的燃燒裝置，對整個爐窯的生產(chǎn)至關(guān)重要。近幾年新建造的大型燃氣爐窯和燃煤爐改造的燃氣爐窯逐漸增多。 </p> <p> 燒嘴正常的運行，對產(chǎn)品質(zhì)量高低和企業(yè)運行成本都有很大影響。原則上講在對燃氣工業(yè)爐設(shè)計時，針對燃氣燒嘴的系統(tǒng)設(shè)計非常嚴格，新建造的燃氣爐會有專業(yè)設(shè)計者對燃燒系統(tǒng)進行論證，模擬實驗，但對于從燃煤爐窯改造成燃氣爐窯的燃燒系統(tǒng)就很少有專業(yè)人員進行計算，而只是采用所謂的經(jīng)驗數(shù)據(jù)，但這樣的在很大程度上會導(dǎo)致燃料浪費嚴重，企業(yè)成本增加，甚至失去市場競爭力。有焰燒嘴種類很多，結(jié)構(gòu)型式各不相同，它主要根據(jù)煤氣的種類、火焰長度、燃燒強度來決定。</p><div

下面我們來分析一下燒嘴點火故障原因及解決辦法：一般燒嘴都配備有點火電極及通常所說的火花塞。首先觀察火花塞是否正常打火，若不打火，請確認以下條件：點火電極要與地極之間保持約2mm的比較好距離。點火變壓器（TZI/TRE820）是否有高壓輸出：先確認燒嘴控制器(SFD258或BMU)的變壓器供電端子是否有電壓輸出，然后確認點火變壓器是否完好或接線是否正確。點火電極是否在燒嘴內(nèi)部短路，造成沒有在點火區(qū)域打火。需查看燒嘴內(nèi)部電極絕緣情況。如火花塞能夠正常打火，而不能看到火焰，請確認空燃氣供應(yīng)情況，并調(diào)整空氣和燃氣的壓力到合適的范圍。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。在確定有燃氣的情況下，空氣壓力太大或太小都有可能無法點燃。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(guān)技術(shù)資料或咨詢廠家。一般情況下空燃氣壓力越小點火成功率越高。以BSIO系列燒嘴為例，450KW小火比較好狀態(tài)是：空氣壓力，燃氣壓力小于。

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。安徽碳化硅燒嘴批發(fā)哪家好</p><p
