加熱爐【氣堵】難題,科晶電爐成功解決
新聞分類:  公司動態    瀏覽:6904    日期:2011/10/13    
    爐子泛起“氣堵”現象,該聯120萬噸/年油氣分離器液位馬上攢高,爐子泛起干燒(因為氣堵,原油在煙道盤管預熱后無法進入爐膛管束加熱)情況,箱式爐加熱爐入口壓力急速上升,系統運行極不不亂,存在種種安全隱患,因為“氣堵”發生頻繁,職工們只有將爐子熄火,等到其天然冷卻后,通過入爐盤管排污閥排掉管束內的氣體,排除爐子故障,重新啟動加熱爐加熱,這也無形的增加了崗位職工的工作強度。


    鑒于上述情形,科晶電爐技術職員在自己試探解決方案的同時,也和外面有關研究加熱爐方面的專家進行溝通,尋求最佳解決方案,但加熱爐“氣堵”現象泛起的概率相稱低,專家們對與解決這一題目一時也無定論,一時“氣堵”挫折擺在了科晶電爐技術職員眼前。


    “只要是出產上的題目總會有解決的辦法”,科晶電爐技術職員抱著這個決心開始了技術攻關,在研究過程中發現,因為原油在進入加熱電爐加熱之前中間尚有分離不徹底的自然氣存在,這樣一來原油從加熱爐管徑較小、回環彎度大煙道盤管進入預熱時,這部門自然氣便會分離出來,并蘊蓄在盤管拐彎出形成氣泡,阻止原油通過,造成“氣堵”的情況。


    該爐的改造成功不僅大大節約了加熱爐的檢驗用度,還將為其它型號相同爐子改造提供理論和實踐依據。題目的癥結找出之后,技術職員便對管式爐實施了技術改造,他們將原油進爐管線繞開煙道盤管管束,直接連接到加熱爐爐膛盤管進口,改變了原來原油進爐加熱路線,使得“氣堵”挫折得到徹底解決。

    加熱爐系列爐負責該聯120萬噸/年中質原油的加熱,但長期以來,因為該爐煙道原油盤管管束過小,時常泛起加熱爐“氣堵”現象,導致該爐熱效率低下,原油破乳受到一定影響。


    該爐改造后已通入運行,經觀察發現,氣堵現象再未泛起過,系統運行平穩,加熱爐溫度較以前比擬較進步了近20攝氏度,保證了油氣處理的溫度需要。
