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(dòng)能，通過液膜或液柱受空氣的剪切擾動(dòng)而使燃油霧化。這種燒嘴的優(yōu)點(diǎn)是結(jié)構(gòu)簡單、運(yùn)行成本低。缺點(diǎn)是當(dāng)負(fù)荷變小時(shí)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(jī)械霧化燒嘴機(jī)械霧化燒嘴是將燃油的機(jī)械能轉(zhuǎn)化為霧化能量，常見機(jī)械霧化燒嘴是轉(zhuǎn)杯式霧化燒嘴。此類燒嘴對機(jī)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(dòng)霧化燒嘴氣動(dòng)霧化燒嘴是利用空氣或蒸氣的高速運(yùn)動(dòng)對液膜或液柱進(jìn)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(shí)現(xiàn)破碎霧化。氣動(dòng)霧化燒嘴的優(yōu)點(diǎn)是調(diào)節(jié)范圍廣、霧化性能好。蘇州燒嘴價(jià)格表可分為蓄熱式燒嘴、輻射管燒嘴、可調(diào)溫?zé)?、低氮燒嘴等多種新型節(jié)能燒嘴。</p><div

在早期的使用過程中，車間發(fā)現(xiàn)主燒嘴存在諸多缺陷：一是使用壽命短，更換頻繁導(dǎo)致燃燒室溫度波動(dòng)，既增加生產(chǎn)成本，又影響生產(chǎn)組織，影響爐窯壽命。二是燒嘴積碳清理裝置拉桿向外伸出，影響工作通行，存在安全隱患。三是無觀察孔，無法了解燒嘴積碳情況和爐內(nèi)天然氣燃燒狀況，加大了積碳清理的頻次和勞動(dòng)強(qiáng)度。首先，針對使用壽命較短問題，選取不同材質(zhì)的燒嘴進(jìn)行試驗(yàn)對比，材質(zhì)為316s不銹鋼燒嘴投入使用一個(gè)多月，管壁被燒穿，影響燃燒效果；另一種310S耐熱不銹鋼燒嘴經(jīng)投入使用一年多，未發(fā)現(xiàn)燒穿現(xiàn)象，效果理想。以一臺(tái)爐18個(gè)燒嘴來計(jì)算，10臺(tái)爐一年可節(jié)省126萬元。</p><p> 下面我們來分析一下燒嘴點(diǎn)火故障原因及解決辦法：一般燒嘴都配備有點(diǎn)火電極及通常所說的火花塞。首先觀察火花塞是否正常打火，若不打火，請確認(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是否正確。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。如火花塞能夠正常打火，而不能看到火焰，請確認(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ΑＴ诖_定有燃?xì)獾那闆r下，空氣壓力太大或太小都有可能無法點(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?，此時(shí)要查看相關(guān)技術(shù)資料或咨詢廠家。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>

1.燒嘴接地是否良好（要求燒嘴與點(diǎn)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(hào)。 3.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內(nèi)。 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(hào)回路上，查看是否有μA電流經(jīng)過，一般要求大于2μA直焰燒嘴：又稱長焰燒嘴，火焰較長，一般窯爐上采用較多。蘇州冶煉燒嘴哪家便宜</p><p style="text-indent:25px">平焰燒嘴氣流的軸向速度很小，得到的是徑向放射的扁平火焰。遼寧工業(yè)燒嘴</p><p
