耐火材料施工廠家告訴您又一新式耐火材料,不僅耐溫又節能


動力的不可再生和動力的持續使用,動力和環境污染雙重對立,動力與環境問題給鋼鐵企業和陶瓷工業等職業的快速開展帶來限制性影響,節能降耗和減少排放是企業技術進步和可持續開展的必然選擇。工業窯爐是工業加熱的關鍵設備,廣泛應用于國民經濟的高溫工業。工業窯爐又是耗能大戶,其能耗占全國總能耗的25%,占工業總能耗約60%。

 

在工業窯爐的節能過程中,除了熱源改造、燒結工藝改造、焚燒工藝改造和窯爐結構改造外,窯爐用耐火資料和窯具耐火資料功能的好壞對工業窯爐的節能效果有著決定性影響,工業耐火隔熱保溫資料有耐火纖維、耐火澆注料、耐火高溫隔熱保溫涂料、輕質耐火磚、A1302空心球磚及鎂磚等幾種窯爐內襯耐火保溫隔熱資料。

 

工業窯爐中熱量消耗基本上可以分解為產品吸收的熱量、窯具吸收的熱量、煙氣帶走的熱量、窯壁和窯車吸收的熱量、窯體散熱丟失的熱量等幾個部分,其間只是用于產品吸收的熱量是有用能量。我國的動力利用率較低,工業窯爐的熱效率平均為30%,其間鍛造窯爐為5%~20%,熱處理窯爐為8%一25%,連續加熱窯爐和隧道窯的熱效率稍高一些,也只有30%~55%,與國際上工業窯爐的熱效率平均為50%以上相比有較大的差距。

 

為應對動力形勢的嚴峻應戰,工業窯爐節能降耗是開展的必然趨勢。工業窯爐節能與窯襯耐火資料的技術進步、窯爐技術設計和施工密切相關。窯襯耐火資料在工業窯爐中的節能作用是經過多種窯襯耐火資料與隔熱保溫資料組合,選用耐火絕熱一體化輕質耐火資料作為窯體結構資料,使窯體減少散熱丟失和蓄熱丟失達到節能目的。

 

窯襯耐火資料與隔熱保溫資料組合有多種途徑,從傳熱角度出發,計算剖析選用幾種不同熱導率窯襯耐火資料結構組合,對其進行包含熱流密度和外表面溫度的改變等傳熱剖析,為優化工業爐窯襯耐火資料,依據不同的窯爐使用剖析,耐火高溫隔熱保溫涂料阻止熱傳導節能比較好。
