技術介紹
燃煤和燃油鍋爐在運行過程中,尾部受熱面普遍產生積灰,使煙氣阻力增加,排煙溫度升高,嚴重影響鍋爐的正常運行。國內外常用的蒸汽吹灰技術在很多情況下不適于清除鍋爐尾部積灰,除灰效果很不理想,主要原因是蒸汽吹灰會導致煙氣濕度增加,更容易造成積灰和堵塞,有時還會使腐蝕加劇,對含鈣量或含硫量較高的灰更是如此。燃氣脈沖吹灰器是一種性能先進的新一代除灰設備,燃氣脈沖吹灰器利用乙炔或煤氣、天然氣、液化石油氣等常用氣體燃料,在特殊設計的燃燒室中燃燒,并以輸出管上的噴口處發射出沖擊波,通過沖擊波的作用使受熱面上的積灰脫落,除灰效果顯著。然而,對于垃圾爐、冶金培燒爐、生物質爐、玻璃及水泥行業余熱爐等鍋爐,由于鍋爐內產生的煙氣腐蝕性極強,會對燃氣脈沖吹灰器內的噴管和脈沖發生器罐體內側產生嚴重的腐蝕。這種腐蝕現象發生的原因在于燃氣脈沖吹灰器是一種間歇性工作的設備,當系統運行時,噴管及脈沖發生器罐體內的壓力大于煙道內壓力,而當燃氣脈沖吹灰系統停止工作時,噴管及脈沖發生器罐體內壓力驟減,相較于煙道的正壓消失,煙道內的殘余腐蝕性煙氣會進入到壓力損失較大的噴管及脈沖發生器罐體內部,造成腐蝕現象。為了解決這一問題,人們多采用增設一配氣引發柜的方式來防止煙氣倒流至噴管進入脈沖發生器罐體內,現有的配氣引發柜中都配有一主回路和一旁通支路,主回路和旁通支路均配有一電磁閥和調壓閥,當脈沖吹灰系統工作時,主回路通氣,旁通支路截止,當系統停止工作時,主回路截止,旁通支路通氣,使得旁通支路對煙道保持一定的空氣流量,因而可防止殘余煙 ...
