冷、熱態診斷試驗反映出爐膛結焦、粘污及燃燒器的結構和布置等因素是造成爐膛出口煙溫偏高，鍋爐出力下降的主要因素。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。This paper introduces the measurement methods and results of cdq - boiler system for mass and energy balance diagnosis, analyses the technologic economic index at the different product rate, puts forward the measures of decreasing the ratio of coke burning, improving the heat transfer conditions and realizing the optimized control aftertime
