摘要
通过对气肥煤工业指标、反射率指标、基氏流动度、奥亚膨胀度、单种煤成焦光学组织和与无烟煤成焦的焦炭光学组织结构等方面进行全面分析,同时与常用肥煤相关指标进行比较,结果表明,气肥煤变质程度较低,单种煤成焦光学组织以细粒镶嵌结构为主,不利于其在配煤炼焦中的配用.但气肥煤胶质体丰富,流动性好,形成的胶质体在煤粒间的铺展性好,可促进煤粒间的黏结,有利于改善焦炭质量,在配煤炼焦中应合理应用.
The proximate analysis, vitrinite reflectance, Gieseler fluidity, Arnu-Audibert＇s dilatometer, coke optical texture of gas-fat coal and coking texture with anthracite were studied. At the same time, it was compared with commonly used fat coal. The result showed that gas-fat coal^rank is lower, coke optical texture of single coal is mainly fine mosaic structure, which are not useful for coal blending. But gas-fat coal＇s plastic layer is very affluent and with good caking property, they can well spread crack of coal grains. All these are helpful to coal grains caking and coke quality improvement. Gas-fat coal should be rationally blended.
