style="text-indent:25px">下面來(lái)分析一下燒嘴點(diǎn)火故障原因及解決辦法：一、一般燒嘴都配備有點(diǎn)火電極及通常所說(shuō)的火花塞。首先觀察火花塞是否正常打火，若不打火，請(qǐng)確認(rèn)以下條件： 1.點(diǎn)火電極要與地極之間保持約2mm的較佳距離。 2.點(diǎn)火變壓器是否有高壓輸出：先確認(rèn)燒嘴控制器的變壓器供電端子是否有電壓輸出，然后確認(rèn)點(diǎn)火變壓器是否完好或接線是否正確。 3.點(diǎn)火電極是否在燒嘴內(nèi)部短路，造成沒有在點(diǎn)火區(qū)域打火，需查看燒嘴內(nèi)部電極絕緣情況。這個(gè)是過去在使用高壓點(diǎn)火變壓器、點(diǎn)火電極打火常見問題，現(xiàn)在大多數(shù)場(chǎng)合已改用高能點(diǎn)火裝置，這個(gè)利用半導(dǎo)體放電，抗潮濕抗積碳具有自凈能力，而且在點(diǎn)火時(shí)不需要調(diào)整點(diǎn)火距離。上海工業(yè)燒嘴批發(fā)哪家好我們所使用的燃料是鋼鐵生產(chǎn)過程中的副產(chǎn)品，煤氣壓力及其配比時(shí)常發(fā)生很大變化；</p><div

天然氣燒嘴按照空燃混合方式：擴(kuò)散式燒嘴：燃燒所需要的空氣不預(yù)先和天然氣混合。大氣式燒嘴：又稱半預(yù)混合天然氣燒嘴。燃燒所需要的空氣部分與天然氣混合。完全預(yù)混合式燒嘴：燃燒所需要的空氣預(yù)先和天然氣混合，一般多用在無(wú)焰燃燒類型的燒嘴上。特殊功能分類：可分為蓄熱式燒嘴、輻射管燒嘴、可調(diào)溫?zé)?、低氮燒嘴等多種新型節(jié)能燒嘴。用途:天然氣燒嘴是工業(yè)窯爐上常用的燃燒裝置，天然氣燒嘴性能的好壞將很大程度上影響產(chǎn)品的質(zhì)量，合理高效的天然氣燒嘴應(yīng)該能滿足窯爐的燃燒、加熱和產(chǎn)品工藝所滿要求的條件。燒嘴常識(shí):天然氣的燃燒一般分為三個(gè)過程：燃?xì)夂涂諝獾幕旌?；混合氣體的升溫和著火；混合氣體的燃燒?；鹧娣€(wěn)定的條件是，火焰?zhèn)鞑ニ俣群涂扇細(xì)怏w混合物的流動(dòng)速度大小相等方向相反。穩(wěn)定的燃燒：燃?xì)夂涂諝饣旌纤俣瘸^火焰?zhèn)鞑ニ俣葘?dǎo)致火焰離開穩(wěn)定點(diǎn)。燒嘴的回火：燃?xì)夂涂諝饣旌纤俣刃∮诨鹧鎮(zhèn)鞑ニ俣龋鹧嫦驘靸?nèi)部噴射。燒嘴的脫火和回火都不是理想燒嘴的燃燒狀態(tài)，燒嘴多采用穩(wěn)焰盤結(jié)構(gòu)來(lái)達(dá)到良好狀態(tài)。

燒嘴正常的運(yùn)行，對(duì)產(chǎn)品質(zhì)量高低和企業(yè)運(yùn)行成本都有很大影響。原則上講在對(duì)燃?xì)夤I(yè)爐設(shè)計(jì)時(shí)，針對(duì)燃?xì)鉄斓南到y(tǒng)設(shè)計(jì)非常嚴(yán)格，新建造的燃?xì)鉅t會(huì)有專業(yè)設(shè)計(jì)者對(duì)燃燒系統(tǒng)進(jìn)行論證，模擬實(shí)驗(yàn)，但對(duì)于從燃煤爐窯改造成燃?xì)鉅t窯的燃燒系統(tǒng)就很少有專業(yè)人員進(jìn)行計(jì)算，而只是采用所謂的經(jīng)驗(yàn)數(shù)據(jù)，但這樣的在很大程度上會(huì)導(dǎo)致燃料浪費(fèi)嚴(yán)重，企業(yè)成本增加，甚至失去市場(chǎng)競(jìng)爭(zhēng)力。燒嘴操作靈活,能實(shí)現(xiàn)自動(dòng)化流水線生產(chǎn)。</p><div

在使用一些爐溫較高的高溫設(shè)備時(shí)，控制器對(duì)火焰的監(jiān)測(cè)可能會(huì)受到這樣那樣的影響，比如：火焰監(jiān)測(cè)器接收到由爐壁反射來(lái)的紫外光而非來(lái)自所監(jiān)測(cè)燒嘴的火焰。從而導(dǎo)致系統(tǒng)誤判，影響系統(tǒng)正常運(yùn)行。 </p> <p> 所以，為了解決這個(gè)問題，高溫模式因此誕生！ </p> <p> <p> 高溫模式工作原理：<span style="font-size:12px;">燒嘴控制器的高溫模式是將火焰監(jiān)測(cè)回路脫開，而不再對(duì)火焰進(jìn)行實(shí)時(shí)監(jiān)測(cè)的一種工作方式。</span> </p> <p> 這種操作模式的先決條件是必須要有其他手段（如溫度監(jiān)測(cè)）來(lái)確保爐膛內(nèi)火焰的存在。 </p> <p> 這種工作方式使得燒嘴控制器避免了干擾，減少誤判，高溫下保持穩(wěn)定工作。 </p> <p> <br /> </p> <p> <br /> </p> 低壓天然氣燒嘴：天然氣壓力在5kpa以下。上海工業(yè)燒嘴批發(fā)哪家好</p><p

自身預(yù)熱燒嘴又稱換熱式燒嘴，它是將燃?xì)馊肟凇⒅硷L(fēng)入口、點(diǎn)火電極、燃燒室、換熱器和排煙口組合成一個(gè)整體的燃燒裝置。自身預(yù)熱式燒嘴的使用替代了煙道熱交換器，無(wú)需額外占地面積且熱利用效率更高。但自身預(yù)熱式燒嘴由于其應(yīng)用的特殊性和結(jié)構(gòu)復(fù)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(xiàng)，會(huì)在使用過程中避免很多不必要的麻煩。明火直接加熱應(yīng)用中要安裝煙氣導(dǎo)流套：在間接加熱應(yīng)用時(shí)，煙氣可以通過換熱器與輻射管的間隙排出爐膛，從而實(shí)現(xiàn)熱量的交換。在明火加熱時(shí)，我們也需要加裝煙氣導(dǎo)流套來(lái)強(qiáng)制煙氣在這個(gè)環(huán)形間隙中通過，實(shí)現(xiàn)很大程度的熱交換。換熱器與輻射管縫隙較大時(shí)安裝煙氣導(dǎo)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(huì)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(dǎo)流套。廣東燃?xì)鉄於ㄖ瀑M(fèi)用</p><p
