在燃燒過程中，會形成大量可再燃的木碳塵顆粒沉淀在若布袋除塵器理，過多的木碳粉熱積聚，容易引起自燃，因而燃燒布袋，也有可能火星進入布袋除塵器導致陰燃，陰燃區域增加，導致除塵器內部灰塵被捕獲火災燒毀了布袋。</div> <div> 鍋爐布袋除塵器燒袋原因</div> <div> 1.由于除塵管道中的大量火星灰塵以及鍋爐煙氣引起的鍋爐煙氣含煙量高，正常情況下約為10％（大部分火星在8％以下熄滅）。事實上，許多鍋爐沒有達到這個參數，導致氧含量太高，因此可燃物具有好氧環境。</div> <div> 2.加上系統的密封性，以及布袋清灰的壓縮空氣，氧氣含量會更高，這樣火星就可以在管道中自由燃燒。</div> <div> 3.火星不僅可以自由燃燒，而且除塵系統中的灰塵也不會完全燃燒。竹炭粉的特點是易燃材料在320度的溫度下達到點火點。沉積在布袋表面的竹炭粉具有吸熱功能，使其本身充滿熱量，燃燒燒掉布袋。</div> <div> 防止布袋除塵器燒袋的措施<br /> <img alt="布袋除塵器" src="/uploads/allimg/190826/1-1ZR612595H27.jpg"

安裝阻火器裝置，能防止有火星進入除塵器而損傷布袋。</div> <div> 環亞環保自創立以來，以獨特的技術、先進的工藝，嚴謹的態度和不斷創新的理念，堅持深入客戶現場，不斷了解客戶的工況和需求，在工業噴涂車間、4S店、機械加工、裝備制造、汽車制造、電子電氣、食品加工、餐飲、家具制造、化工、造紙、印刷等領域的廢氣、粉塵治理方面積累豐富的理論和實踐經驗。</div> </div> <p
