为了适应下一个十年到来时对电力的需要,工业用电逐渐从非正规发电机组处购买电力,煤矸石电厂出售电力给有关电网,可望将扮演一个非常重要的角色。煤矿近年开发的利用余热发电,也将成为相当重要的一个方面。1991年秋季,一座装机容量为85MW的煤矸石余热发电厂——第一座专门设计的、以烟煤矸石作为主要燃料的电厂——已正式投入生产,供应电力给宾夕法尼亚电力公司,并供应蒸汽给附近的居民用户。该厂位于宾夕法尼亚坎布里亚县埃本斯伯格附近。这座投资1.9亿美元的发电厂,在投产后的头5个月的平均运行率达到98%以上;它与按照工业规程要求,一座新建电厂的运行率近80%的指标相比还是令人满意的。
In order to meet the demand for electricity when the next decade comes, industrial power will gradually purchase electricity from informal generating units. Coal gangue power plants sell electricity to the relevant power grid and are expected to play a very important role. The utilization of waste heat power generation developed by coal mines in recent years will also become a very important aspect. In the fall of 1991, a coal gangue waste heat power plant with an installed capacity of 85 MW—the first specially designed power plant with bituminous coal as the main fuel—was formally put into production, supplying electricity to Pennsylvania Power Company and supplying steam to Resident users nearby. The plant is located near Ebensberg in Cambria County, Pennsylvania. The average investment rate of the 190 million U.S. dollar power plant after the start of production exceeded 98%; it is still more than an 80% rate of operating rate for a newly built power plant according to industrial regulations. satisfied.
