一、美国煤炭加工及转化情况美国煤炭加工转化搞得比较好,整个过程注重净化环境,保护生态,通过加工、转化,使煤炭增值,提高经济效益。很多地方已取消了原煤供应,按燃烧设备所需煤炭品种,规格、质量进行生产和供应。这对节约能源,降低消耗,发挥煤炭最大效益很有帮助。筛分、洗选、型煤等物理转化等方面技术是成熟的,已经推广。这些技术虽系初级转化,但投资省、见效
First, the United States, the processing and conversion of coal United States made better processing and conversion of coal, the whole process focus on the purification of the environment, ecological protection, through the processing, conversion, the value of coal, improve economic efficiency. In many places, the supply of raw coal has been canceled and the production and supply of coal varieties, specifications and quality required for combustion equipment have been canceled. This is very helpful for saving energy, reducing consumption and maximizing the benefits of coal. Screening, washing, briquette and other physical transformation technology is mature, has been promoted. Although the primary conversion of these technologies, but the investment province, effective
