摘　　要：以焦作煤为研究对象,从煤质数据对比、燃烧率、可磨性、灰熔点、输送性能等方面加以研究。探讨了焦作煤的物理特性以及煤粉粒度、富氧率、风温对其燃烧性能的影响;以及煤粉粒度、水分对输送性能的影响;结果表明:增加烟煤比例可显著提高焦作煤的燃烧性能,提高焦作煤-200目粒度可改善焦作煤的燃烧性能和输送性能,焦作煤的水分应控制在1.0%～2.0%。The paper researched Jiaozuo coal from coal quality data contrast, combustion rate, grindability, ash melt- ing point, delivery performance, etc, and discussed the effects of its physical properties , coal particle size, oxygen enrich- ment rate and wind temperature on combustion ratio; the effects of coal particle size and moisture on its delivery perform- ance ; the results show that ： the increase of bituminous coal ratio can significantly improve the jiaozuo coal combustion per- formance, the - 200 mesh particle size increase can improves jiaozuo coal combustion performance and delivery perform- ance, jiaozuo coal moisture should be controlled in 1.0% ~ 2.0%
