近年来,随着我国经济社会的快速发展和人们生活水平的提高,人们对煤能源的使用需求日益增强。在原煤经开采出来后,不能直接作为能源材料加以使用,必须对其进行洗煤与选煤等过程之后,才能得到精煤,进而被作为能源材料使用。随着科学技术的发展和进步,越来越多的新型洗煤选煤技术及其设备被研发出来,并逐渐投入到实际应用,使得原煤的利用效率大大提高,有效地提高了能源利用率。
In recent years, with the rapid economic and social development in our country and the improvement of people’s living standard, the demand for the use of coal energy is increasing day by day. After the raw coal is recovered, it can not be directly used as energy source materials. After coal washing and coal preparation, it must be cleaned before it can be used as energy source material. With the development and progress of science and technology, more and more new coal washing and coal preparation technologies and their equipment have been developed and gradually put into practical application, which greatly improves the utilization efficiency of raw coal and effectively improves the energy utilization rate.
