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，上海窯爐燒嘴,在噴口形成高速氣流,當燒嘴在滿負荷時(額定功率)，上海窯爐燒嘴,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，上海窯爐燒嘴,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(yīng)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)。煤氣與熱風(fēng)保持一定的角度與速度差均勻的混合，在燃燒室里進行劇烈的燃燒反應(yīng)。上海窯爐燒嘴</p><div

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)運動、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。燃氣燒嘴批發(fā)公司擴散式燒嘴: 一次空氣系數(shù)為0，燃燒空氣全部依靠二次空氣。</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。 </p> <p> <br /> </p><p style="text-indent:25px">燒嘴熄火原因分析：一次風(fēng)配比過低時，加熱爐效率就會降低。一次風(fēng)配比過高時，火焰很短，根部與燒嘴明顯脫節(jié)，會被吹離燒嘴而引起熄火。二次風(fēng)配比過低時，空氣過剩系數(shù)小，燃燒熱效率高，燃氣濃度大，火焰?zhèn)鞑ニ俣鹊?，當火焰?zhèn)鞑ニ俣刃∮诨旌先紵龤怏w噴射速度時，火焰會被吹離燒嘴而引起熄火。二次風(fēng)配比過高時，加熱爐熱效率降低爐膛負壓過高時，漏風(fēng)量增加，燃燒熱效率降低。爐膛負壓過低時，混合燃燒氣體中空氣流速降低，火焰?zhèn)鞑ニ俣冉档蛯?dǎo)致熄火(爐外大氣壓降低也是爐膛負壓過低的原因之一) 燃氣噴射速度超過燒嘴比較大負荷時，火焰?zhèn)鞑ニ俣刃∮诨旌先紵龤怏w噴射速度，火焰很長，根部與燒嘴明顯脫節(jié)，會被吹離燒嘴而引起熄火燃氣噴射速度低于燒嘴比較大負荷時，火焰?zhèn)鞑ニ俣却笥诨旌先紵龤怏w噴射速度，火焰很短，根部向燒嘴口收縮，可能逆流進燒嘴口而引起熄火燒嘴設(shè)計負荷偏大時，若不采取有效措施，將導(dǎo)致混合燃燒氣體噴射速度降低而引起熄火。高中壓天然氣燒嘴：天然氣壓力在5kpa以上。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海窯爐燒嘴,天燃氣燒嘴" src="https://tyunfile.71360.com/UploadFile/wds2020/637311308163466796/1573981.png"></div><p style="text-indent:25px"> 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。如果點火時看到明火。燃氣電磁閥被切斷，說明火焰檢測回路有問題。如今幾乎所有的燒嘴控制器（比如SFD258或BMU460）都有火焰檢測和熄火保護功能，如果在點火時檢測到火焰，電磁閥保持打開狀態(tài)，點火程序完成，點火成功。如果在點火時沒有火焰信號回到控制器，則在安全時間結(jié)束時，控制器會迅速切斷燃氣電磁閥，輸出故障信號。這時我們要確認以下條件：lUV紫外線監(jiān)測方式：查看UV火檢是否正常，接線是否正確，必要時更換UV火檢。l電離式檢測方式：查看檢測電極和燒嘴控制器（如SFD258的5號端子）信號回路是否暢通。電離式檢測方式下，檢測不到電流有幾種情況：燒嘴接地是否良好（要求燒嘴與點火控制器之間共地）；空燃比不合適造成的火焰不規(guī)則，無法監(jiān)測到連續(xù)穩(wěn)定信號；檢測電極和燒嘴內(nèi)部是否短路而干擾微安電流回到燒嘴控制器SFD258內(nèi)。檢測微安電流可以用微安表，一端接在監(jiān)測電極，另一端接在燒嘴控制器信號回路上，查看是否有μA電流經(jīng)過，一般要求大于2μA。配風(fēng)式燒嘴：依靠鼓風(fēng)機強制配助燃風(fēng)，風(fēng)機通常為高壓離心風(fēng)機。成都定制燒嘴哪家便宜</p><p style="text-indent:25px">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。上海窯爐燒嘴</p><p style="text-indent:25px">碳化硅燒嘴具有以下優(yōu)點： 1、硬度更好，燒嘴，耐沖刷性能更好，使用壽命更長，成本較低。 2、材料彈性更好，噴嘴的壁厚更加薄，外形更加緊湊，同等規(guī)格的噴嘴重量更輕。而且運輸木箱也不容易碎裂 3、材料表面光滑無氣孔，內(nèi)部流道更加光滑，不容易結(jié)垢，霧化更加均勻。 4、傳熱更好，燒嘴不容易因為冷熱交替而產(chǎn)生開裂變形。 5、另外，反應(yīng)燒結(jié)碳化硅燒嘴可以做全尺寸的螺旋燒嘴和切向空心錐燒嘴，碳化硅燒嘴套，但是氮連接碳化硅只能做2英寸以上的大流量切向空心錐燒嘴。上海窯爐燒嘴</p><p
