张店热电厂1、2号炉是哈尔滨锅炉厂的HG110/100—1型,3号炉是上海锅炉厂的SG220/100—M295型。各炉炉型均为单汽包自然循环、中间储仓式煤粉炉,燃烧器为四角布置双切圆燃烧;各角一、二、三次风喷口布置自上而下分别为三、二、一、二、一、二;燃烧系统采用一次热风送粉,制粉乏气作为三次风,二次风为热空气助燃。1、2号炉于1986年投运,3号炉于1989年投运后,1、2号炉倒替运行。1991年3月,2号炉水冷壁管发生爆管事故,停炉检查发现在燃烧区域内的水冷壁管外部腐蚀严重,但在3号炉投运前未发现此情况。随后其余两台炉也发现类似情况。1、2号炉于1991年至1992年先后换管。去年4月1号炉大修换管后,电厂
Zhangdian Thermal Power Plant No.1 and No.2 furnaces are HG110 / 100-1 type of Harbin Boiler Works and No. 3 furnaces are SG220 / 100-M295 type of Shanghai Boiler Works. Each furnace type is the natural circulation of single drum, the middle bin type pulverized coal fired furnace, the burner is arranged in four corners of the double tangential combustion; angle one, two, three air vents arranged from top to bottom three, two, One, two, one, two; combustion system uses a hot air feeding powder, powder gas as the tertiary air, secondary air for the combustion of hot air. Furnaces No. 1 and # 2 were put into operation in 1986 and No. 3 furnaces were put into operation in 1989. Furnaces No. 1 and # March 1991, No.2 furnace water tube explosion pipe burst, shutdown inspection found in the combustion area outside the water wall tube corrosion serious, but in the furnace before the 3 did not find this situation. Then the other two furnaces also found a similar situation. 1,2 furnaces in 1991 to 1992 has changed tube. April 1 last year, furnace overhaul tube, power plant
