【摘要】Wetting Heat of various ranks of coals in water was measured by using SETARAM C80D Calorimeter. The data were correlated to coals' slurryability which is characterized by the solid load at the viscosity of 1 Pa·s and 25℃. The results showed that the heat of wetting by water decreases as coal rank increases in the range of brawn coal to bituminous coal with carbon content of 89%～90% (daf), and then, increases a little for anthracite. This trend fitted well to the relationship of slurryability to coal rank. The heat of wetting was also correlated to the inherent moisture content and the oxygen content of coal, which are commonly considered as slurryability indication parameters. Hence, the wetting heat is another measure of coal's slurryability. 【总页数】5页(86-90)
