高浓度煤水泥桨(CWM—CoaI Wat er Mixtare)是有效利用煤的方法之一、如果作为高炉燃料使用,则是一种很有希望的燃料,因为与高炉喷吹煤粉相比,这种工艺安全并且没备费低廉。为了保证煤水泥桨有一定流动性,要控制水份含量,要选择吸水性差的致密的煤;煤的粒度组成要适当,以便减小空隙率;添加适宜的界面处理剂,以便减小煤粒之间的结合力。根据Rist操作线进行计算表明:煤水泥桨喷吹量的限制环
The CWM-CoaI Wat er Mixtare is one of the most efficient ways to use coal and is a promising fuel if used as a blast furnace fuel because, compared to blast furnace pulverized coal injection, this Process safe and inexpensive. In order to ensure a certain degree of mobility of coal slurry, to control the moisture content, we should choose the dense water with poor water absorption. The coal particle size composition should be appropriate in order to reduce the porosity; add suitable interface treatment agent to reduce the coal particles The binding force between. Calculations based on the Rist operating line showed that the restriction of the blowing volume of coal-cement paddles
