动力煤配煤技术基础

阐述了我国动力煤利用现状．从煤在不同类型锅炉的燃烧方式出发，讨论了煤质特性对燃烧工况及对环境的影响，以及一些非加和性煤质指标，如可磨性、粒度组成、煤炭熔融性等对动力配煤的影响，进而提出选定动力配煤方案的原则．

THE TECHNICAL FUNDAMENTAL OF COAL BLENDING FOR STEAM COALS

The status of steam coal utilization in China was introduced. In the view of combustion techniques of different types of boiler, the effect of characteristics of coal on the combustion work efficiency and environment was discussed. Some parameters of coal properties which are not a linear combination of the individual index in weight of blending coal, such as Hardgrove grindability index (HGI), screen analysis, ash fusibility, ect., were also discussed. Furthermore, the principles of blending system for steam coals were described for making a right choice on the blending scheme.
