輕/重油燃燒器常見故障

①燃料油壓力低,無法達到供油量該系統由燃料油罐、燃料油泵、燃燒油泵、噴油閥(油嘴)等組成,系統壓力低,不僅無法保證霧化效果,更無法完成燃燒的供油量。

 

②燃料油溫(wen)度(du)較(jiao)低(di)(di),粘(zhan)度(du)增大(da)(da)油溫(wen)的高低(di)(di),影響(xiang)霧(wu)化效果,溫(wen)度(du)低(di)(di)粘(zhan)度(du)大(da)(da)不易霧(wu)化且易導致過濾器(qi)(網(wang)格300µm)堵塞油壓(ya)降(jiang)低(di)(di),由于粘(zhan)度(du)影響(xiang),燃燒不充分無法(fa)保證外輸溫(wen)度(du)并有大(da)(da)量黑煙和爐膛內積碳;該地區冬季漫長(chang)環(huan)境溫(wen)度(du)較(jiao)低(di)(di),燃燒器(qi)低(di)(di)溫(wen)下運行,自控系(xi)統自帶燃料油低(di)(di)溫(wen)報警或(huo)低(di)(di)溫(wen)報警系(xi)統自動(dong)關閉燃燒器(qi)。

 

③高(gao)含(han)水(shui)(shui),導(dao)致(zhi)停爐(lu)投產初期(qi),來油(you)含(han)水(shui)(shui)較低(di),未(wei)進行(xing)燃料(liao)油(you)罐底水(shui)(shui)切放(fang),長期(qi)運(yun)行(xing)后,油(you)罐內積水(shui)(shui)較多,出現高(gao)含(han)水(shui)(shui)停爐(lu)事(shi)件,切放(fang)底水(shui)(shui)后,再無高(gao)含(han)水(shui)(shui)停爐(lu)事(shi)件的發生。
