【摘要】 利用有色冶炼固废中含有碱金属和过渡金属的性质，以其为原料制备燃煤催化剂。测试了掺入燃煤催化剂燃烧后灰分中的重金属含量，分析了煤粉燃烧的燃烧性能和燃烧动力学。结果表明：使用固废尾渣制备的燃煤催化剂不会影响水泥窑中的重金属含量。加入催化剂后，煤的着火点和燃尽点分别下降了4.02℃和11.84℃,最大燃烧速率提高了0.22%/min,提前达到最大燃烧速率的温度。加入燃煤催化剂会少许增加燃烧烈度，着火指数和燃尽指数分别提升了8.0%和7.5%,煤粉燃烧反应的活化能降低4.4%。更多还原

【Abstract】 The use of non-ferrous smelting solid waste containing alkali metal and transition metal this feature, it was used as raw material to prepare coal-burning catalyst.The content of heavy metals in ash after combustion with coal catalyst was tested, the combustion performance and kinetics of pulverized coal combustion were also analyzed.The results show that the coal burning catalyst prepared with solid waste tailings will not affect the content of heavy metals in cement kiln.With the addition of catalyst, the ignition point and burnout point of coal decrease by 4.02 ℃ and 11.84 ℃ respectively, and the maximum combustion rate increases by 0.22%/min, reaching the temperature of maximum combustion rate in advance.The addition of coal burning catalyst will slightly increase the combustion intensity, ignition index and burnout index increase by 8.0% and 7.5% respectively, and the activation energy of pulverized coal combustion reaction decreases by 4.4%.更多还原
