摘　　要：煤质的好坏不仅影响到锅炉的燃烧工况调整、机组的安全运行和电厂的发电能耗,而且煤质和煤种的变化对输煤系统也有直接的关系。从经济性和可靠性角度分析探讨了煤的发热量、灰分、水分等衡量煤质的特性指标对输煤系统的影响。The coal quality and type not only affect the boiler combustion, unit operation, and energy consumption for power generation in power plants, but also has direct relation with the coal handing system. The influence of coal characteristic indices such as caloricity, ash content, and water content on the coal handling system is discussed in the aspects of economy and reliability.
