近年煉鐵廠通過堅持「精料」方針,改善燒結礦質量,提高風溫,增大富氧,實施大噴煤,使入爐焦比有明顯下降;燒結堅持用好生石灰,推行厚料層燒結,實施多項技術攻關,固體燃耗大幅度下降;同時加強能源基礎管理,節能工作取得長足進步,節能創效益1億元以上。This article aims at the boiler ' s problems in operation : 1 ) under nominal load, the smoke temperature at the outlet of hearth reaches 1200, far more exceeds 1050 the original designed temperature. this will always result in slag inside boiler and the temperature of overheater ' s pipe superheat, so that boiler cannot take nominal load and all these influence boiler ' s nomal operation heavily, 2 ) this article also studied the reason why the assistant oil becoming necessary when coal changes. during the nomal operation, many factors ( makeup of combustor and its disposal, smirch and encrust of water wall, excessive air coefficient, temperature of primary air, coal type and density of coal dust ) can deviate the designed working conditions, then affect the boiler ' s nomal operation
本文針對該鍋爐在實際運行中存在的問題:在額定負荷下,爐膛出口超溫、低溫段過熱器前煙溫高達936 ,遠遠超過815的設計值;噴燃器四周水冷壁結焦嚴重,過熱器管壁溫度超標,無法帶上額定負荷;甚至有時因燃煤質量的變化,必須投油助燃的嚴重情況進行了分析研究。在實際生產過程中,燃燒器的結構、布置,水冷壁的粘污、結垢,過剩空氣系數、一次風溫、煤種及其濃度變化等許多因素都會偏離鍋爐的設計工況,從而影響爐內的傳熱和燃燒,造成爐膛出口超溫、水冷壁結渣等問題。New five - stage cyclone pre - heater system, high efficiency air girder grate cooler, multi - passage pulverized coal burner, davison heat temperature fan, luqi bs930 electrical dust collector, as well as chain - board elevator, chain conveyor adopted in this production line can ensure that the technology is advanced compared to other production lines with the same scale
