下面我們來(lái)分析一下燒嘴點(diǎn)火故障原因及解決辦法：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(guān)察火花塞是否正常打火，若不打火，請(qǐng)確認(rèn)以下條件：點(diǎn)火電極要與地極之間保持約2mm的比較好距離。點(diǎn)火變壓器（TZI/TRE820）是否有高壓輸出：先確認(rèn)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(rèn)點(diǎn)火變壓器是否完好或接線(xiàn)是否正確。點(diǎn)火電極是否在燒嘴內(nèi)部短路，造成沒(méi)有在點(diǎn)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(qǐng)確認(rèn)空燃?xì)夤?yīng)情況，并調(diào)整空氣和燃?xì)獾膲毫Φ胶线m的范圍。合理的空燃?xì)獗壤屈c(diǎn)火的必要條件，這就要求我們要提供合理的空燃?xì)鈮毫?。在確定有燃?xì)獾那闆r下，空氣壓力太大或太小都有可能無(wú)法點(diǎn)燃。不同品牌不同型號(hào)的燒嘴所要求的空燃?xì)鈮毫τ兴煌藭r(shí)要查看相關(guān)技術(shù)資料或咨詢(xún)廠(chǎng)家。一般情況下空燃?xì)鈮毫υ叫↑c(diǎn)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?xì)鈮毫π∮凇?</p>

style="text-indent:25px">燒嘴也叫燃燒器，是工業(yè)燃料爐上用的燃燒裝置的俗稱(chēng)，可理解為“燒火的噴嘴”的簡(jiǎn)稱(chēng)。通常指的是燃燒裝置本體部分，有燃料入口、空氣入口和噴出孔，起到分配燃料和助燃空氣并以一定方式噴出后燃燒的作用。燒嘴磚是燃燒裝置的重要組成部分。燒嘴磚的作用有： 1）將燃料在燒嘴磚內(nèi)加熱至著火溫度，使其易于點(diǎn)火并迅速燃燒。 2）在燒嘴磚內(nèi)保持一定的高溫，使燃燒過(guò)程穩(wěn)定，避免產(chǎn)生脈動(dòng)或燃燒中斷現(xiàn)象。 3）組織火焰形狀，滿(mǎn)足加熱工藝的要求。 4）使燃料和空氣進(jìn)一步混合。燒嘴按所用材質(zhì)分為：鉻剛玉質(zhì)燒嘴磚，剛玉莫來(lái)石燒嘴磚，高鋁莫來(lái)石燒嘴磚，粘土質(zhì)燒嘴磚，碳化硅燒嘴磚。鍋爐點(diǎn)火燒嘴的工作條件比較惡劣，長(zhǎng)期受爐膛高溫輻射和火焰沖刷，容易造成蠕變、高溫變形和損壞。鄭州鑄鐵燒嘴哪些品牌</p><p
