style="text-indent:25px">無論任何類型的燒嘴都有一個點火過程，由于對產(chǎn)品性能的不熟悉，或者不了解基本的點火操作流程，可能在燒嘴初期點火時遇到點火故障，這往往影響整個工程項目的進度。電離式檢測方式下，檢測不到電流有幾種情況： 1.燒嘴接地是否良好（要求燒嘴與點火控制器之間共地）。 2.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。 3.檢測電極和燒嘴內部是否短路而干擾微安電流回到燒嘴控制器內。 4.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廣東燃氣燒嘴批發(fā)市場避免點火燒嘴損壞的方法燒器區(qū)域含氧量增多，從而使點火燒嘴高溫富氧燒蝕損壞。</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">如火花塞能夠正常打火，而不能看到火焰，請確認空燃氣供應情況，并調整空氣和燃氣的壓力到合適的范圍。 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。</p><p style="text-indent:25px"> 碳化硅燒嘴中管螺紋接頭的主要制作材料為不銹鋼，螺紋連接方式可分為內螺紋連接和外螺紋連接。這種接頭多用于連接建筑、水利工程、橋梁建筑的管道。壓力表的接頭和接觸液體的零件都是由黃銅制成，主要用于測量對銅和銅合金無腐蝕性、無性，且不易結晶和沉淀的氣體或液體壓力。碳化硅燒嘴的這種儀表要求垂直安裝，負荷穩(wěn)定。電磁閥也是一種碳化硅燒嘴配件，具有內螺紋連接口。電磁閥的閥體通常是由不銹鋼和黃銅制造的，它的活塞結構特別，耐磨度高，并且在工作時不會產(chǎn)生任何的噪音。燒嘴按所要求的濃度、速度、湍流度和混合方式送入爐膛，并使燃料能在爐膛內穩(wěn)定著火與燃燒的熱能裝置。</p><div

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，自身文丘里式結構，可吸入外界空氣，一般燒嘴功率較小。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。按照空燃混合方式：擴散式燒嘴：燃燒所需要的空氣不預先和天然氣混合。大氣式燒嘴：又稱半預混合天然氣燒嘴。燃燒所需要的空氣部分與天然氣混合。完全預混合式燒嘴：燃燒所需要的空氣預先和天然氣混合，一般多用在無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、可調溫燒嘴、低氮燒嘴等多種新型節(jié)能燒嘴。焰燒嘴主要應用與加熱工件不能與明火接觸的工業(yè)爐上。鍛造爐燒嘴價格</p><p style="text-indent:25px">完全預混燒嘴:一次空氣系數(shù)等于過剩空氣系數(shù)，約為1.05～1.15，燃燒不需要二次空氣。碳化硅燒嘴定制價格</p><p style="text-indent:25px">下面來分析一下燒嘴點火故障原因及解決辦法：一、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： 1.點火電極要與地極之間保持約2mm的較佳距離。 2.點火變壓器是否有高壓輸出：先確認燒嘴控制器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。 3.點火電極是否在燒嘴內部短路，造成沒有在點火區(qū)域打火，需查看燒嘴內部電極絕緣情況。這個是過去在使用高壓點火變壓器、點火電極打火常見問題，現(xiàn)在大多數(shù)場合已改用高能點火裝置，這個利用半導體放電，抗潮濕抗積碳具有自凈能力，而且在點火時不需要調整點火距離。碳化硅燒嘴定制價格</p><p
