| 摘 要： | 火电机组的锅炉燃烧效率及标准煤耗与煤质、发电负荷率、机组环境温度有着直接的联系,供电煤耗与煤炭发热量在一定范围内呈正相关关系;而煤炭销售收入与煤质、价格、原煤到商品煤的洗选深度即资源回收率有着直接的关联;煤炭的可售资源量与煤质又是负相关,单方追求效益的最大化都会导致整体效益的下降。

| Abstract: | The boiler combustion efficiency and standard coal consumption of the thermal power unit have the directly relationship with the coal quality, load factor, and environment temperature of power u- nit. There is a positively correlation between the net coal consumption and the coal calorific value within a certain range. Moreover, the sale revenue of coal depends directly on coal quality, price, separation and recovery from raw coal to commercial coal （recovery rate）. The saleable quantity of coal, however, shows negatively correlation with the coal quality. Thus, unilateral pursuing for the maximization of benefits will lead to the decline in overall efficiency. |
