水煤浆是近年出现的一种新型液体燃料和化工原料。近十多年来煤浆研究得到举世注目。它是用一定细度的煤粉与水以及1%左右的添加剂掺混而成的均匀混和物,可以象重油一样来输送、贮藏和燃用。一般燃用水煤浆干质煤粉浓度在70%左右,理论燃烧温度比重油低100多度,燃烧效率可达98%以上。一、水煤浆技术近年发展的原因进入八十年代以来,燃料科学研究的重点已从油煤浆转为水煤浆,究其原因,大致有以下 Coal-water slurry is a new type of liquid fuel and chemical raw material appeared in recent years. Nearly a decade of coal slurry research has attracted worldwide attention. It is a uniform mixture of coal and water with a certain degree of fineness and about 1% additives, which can be transported, stored and fired like heavy oil. The general burning of coal water slurry dry coal concentration of about 70%, the theoretical burning temperature of more than 100 degrees lower than the oil, combustion efficiency up to 98%. First, the reasons for the development of coal-water slurry technology in recent years into the 1980s, the focus of fuel science has changed from coal-oil slurry into coal-water slurry, the reason, roughly the following
