不同粒度煤粉颗粒元素含量变化特性研究
Study on Characteristic of Element Change of Pulverized Coal in Different Granularity
摘要
Abstract
Since a long time, many scholars studied on granularity and ignition, combustion and burnout characteristics combined with particle granularity distribution and proximate analysis of pulverized coal. But it isn't enough that study on the change of element component in the difference of granularity.In the milling process, the mineral of coal will be separated out because of decrease of granularity and milling of coal. So, the element component and physical character of pulverized coal will be changed in the difference granularity. Elementary analyzer made in Germany was applied to analyze respectively samples of pulverized coals over four kinds of different particle sizes from Xingtai power plant and Yangquan power plant. The results show that there is great influence of particle granularity of pulverized coal on fractional characteristic, thereby element percent content was influenced. The sulfur formation and mineral characters was concluded.关键词
