壓力霧化燒嘴壓力霧化燒嘴是靠燃油自身的壓力轉(zhuǎn)化為噴射動能，通過液膜或液柱受空氣的剪切擾動而使燃油霧化。這種燒嘴的優(yōu)點是結(jié)構(gòu)簡單、運行成本低。缺點是當(dāng)負(fù)荷變小時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 機械霧化燒嘴機械霧化燒嘴是將燃油的機械能轉(zhuǎn)化為霧化能量，常見機械霧化燒嘴是轉(zhuǎn)杯式霧化燒嘴。此類燒嘴對機械能要求較高，一般要求非常高的轉(zhuǎn)速才能霧化所需的剪切力。 1.1.3 氣動霧化燒嘴氣動霧化燒嘴是利用空氣或蒸氣的高速運動對液膜或液柱進行撞擊、剪切、旋轉(zhuǎn)。氣液兩相產(chǎn)生相對高的相對速度來實現(xiàn)破碎霧化。氣動霧化燒嘴的優(yōu)點是調(diào)節(jié)范圍廣、霧化性能好。鋁合金燒嘴設(shè)備廠家一個燒嘴能否發(fā)揮其較佳的功能，并非**取決于燒嘴本身，它還受到換熱設(shè)備等其他因素的制約。</p><div

820）是否有高壓輸出：先確認(rèn)燒嘴控制器(SFD 258或BMU)的變壓器供電端子是否有電壓輸出，然后確認(rèn)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。碳化硅燒嘴憑借碳化硅的耐火耐高溫的特性具有較強的實用性。</p><div style="width:100%;text-align:
