兰炭作为动力用煤的燃烧性能研究 -

为了全面掌握榆林兰炭作为动力用煤的燃烧性能,在一维火焰燃烧试验炉和煤粉气流着火温度试验炉上对试验样品进行了燃烧性能研究。试验结果表明:尽管兰炭的工业分析、元素分析、发热量和无烟煤接近,但着火性能和燃烬性能明显优于国内典型无烟煤,低于原煤,而兰炭的结渣性能与原煤比较无明显变化。总体而言,兰炭的燃烧性能与原煤及无烟煤具有较大差别,需通过专业试验确定,可作为动力用煤原料或者掺配原料。 In order to master the possibility of using blue-coke as fuel for pulverized coal boiler,the combustion tests of blue-coke were conducted on the one-dimensional flame furnace and pulverized coal ignition temperature test furnace. The results show that the proximate analysis,elemental analysis and calorific value of blue-coke were closed to anthracite. The ignition and burnout performance of blue-coke is superior to typical anthracite in China,but the corresponding performance is lower than raw coal. The slagging property of the two is similar. Overall,there are many differences in combustion performance among char and raw coal,anthracite. The blue-coke could be used as raw material or blending material for power plants
