摘要
将某型号无烟煤粉碎后浸渍过渡金属Cu和Co的硫酸盐溶液,经过烘干、焙烧及研磨处理,研究不同过渡金属硫酸盐催化剂对煤的燃烧性能的影响.采用燃点测定仪测其着火点,X射线衍射仪物相分析.结果表明,过渡金属硫酸盐能改变煤粉的燃烧反应历程,加速煤粉燃烧反应速率,大幅度降低着火点.
One type of anthracite powder was dried, roasted and grinded after being dipped by transition metal Cu and Co sulfate solution with the purpose of the research of impact on combustion properties resulted by the different transition metal sulfate. The results got from igni- tion point detector and X-ray diffraction phase analysis, showed that the transition metal sulfate changed coal combustion process, speeded up the coal combustion rate, significantly reduced ignition point.
