摘　　要：选用了贵州省西南地区4种典型煤种作为研究对象,设计加工了煤燃烧砷、硫析出试验装置,研究了砷、硫的析出规律及影响因素,初步获得了煤燃烧过程中砷、硫的生成动力学参数。结果表明:4种煤的砷、硫析出率均随着燃烧温度的升高而增加,煤中砷析出的反应活化能都要高于煤中硫析出的反应活化能,表明煤中砷析出温度要高于煤中硫析出温度,实验结果与动力学推断相吻合。Four typical coals in southwestern Guizhou were selected as the research object.The test apparatus for arsenic and sulfur emission during coal combustion were established.Moreover,the main factors of arsenic and sulfur emission rate were researched.The kinetics parameters of arsenic and sulfur emission were obtained preliminly during the coal combustion.The results showed that arsenic and sulfur emission rate of four kinds of coal increased with increasing combustion temperature.The arsenic activation energy is higher than that of the sulfur in coal,indicating that the arsenic forming temperature is higher than that of the sulfur in coal.The experimental results are also consistent with the dynamics data.
