摘　　要：基于一维炉火焰试验台,针对北票低热值小颗粒油页岩与褐煤在不同掺混比例、颗粒粒径下的污染物生成规律以及炉内燃尽率的变化趋势进行试验分析,初步掌握了油页岩在多种工况下的燃烧情况。分析结果表明,随着油页岩掺烧比例增大,炉内污染物的排放量呈上升趋势,SO_(2)的最大生成量为2845 mg/m^(3);掺混小粒径颗粒的燃料在一维炉内具有更好的燃烧效率;当粒径较大时,燃料在一维炉内的燃尽程度仅为小粒径的83%~89%。Based on the one-dimensional furnace flame test bench,the pollutant generation rule and the change trend of combustion rate in the furnace of Beipiao low-calorific value small-particle oil shale and lignite under different mixing ratios and particle sizes were analyzed,and the combustion situation of oil shale under various working conditions was preliminarily mastered.The results show that with the increase of oil shale combustion ratio,the emissions of pollutants in the furnace are on the rise,and the maximum amount of SO_(2)is 2845 mg/m^(3).The fuel mixed with small particle size has better combustion efficiency in one-dimensional furnace.When the particle size is larger,the burnout degree of fuel in one-dimensional furnace is only 83%~89%of that of the small particle size.
