摘　　要：在一维沉降炉上对某电厂燃用的几种烟煤及其混煤进行了试验研究 ,通过改变炉膛温度 ,过量空气系数 ,二次风风温 ,一、二次风配比 ,给粉量等 ,分析了这些因素的变化对这几个煤种按不同掺混比组成的混煤燃烧时SO2 排放量的影响 ,为大型电厂锅炉高效清洁燃烧提供了理论依据。The study of some soft coals and blending coals which are used in some power plant, have been carried out in one dimension subsiding furnace.Through changing some factor such as the furnace temperature,excess air factors,the temperature of the second wind ,the ratio of the first wind and the second wind, the quantity of coal powder, the influence on the SO 2 emission about blending coal which blended with different blending ratio was discussed,That provides the theory thereunder to high efficiency clean combustion of large power plant boiler.
