Mineral conversion of Zhundong coal during ashing process and the effect of mineral additives on its ash fusion characteristics

  • 摘要: 利用低温灰化、高温灰化和X射线衍射物相分析相结合的方法对准东煤中矿物质在加热过程中的演变规律进行了研究。结果表明,准东煤中原始矿物质以方解石、高岭石为主,随着燃烧温度的升高,煤灰中矿物质最终生成了铁橄榄石、硅酸钙等。此外,向准东煤中掺加不同比例的高岭土和刚玉混合添加剂,发现随着SiO2/Al2O3比值的降低,煤中生成了钙矾石、钙铝榴石等高熔点物质,准东煤的灰熔点逐步升高。
