The influence of wetting heat in water to coals` slurryability
- Beijing Graduate School (China)
Wetting Heat of varied-rank coals in water was measured by using SETARAM C80D Calorimeter. The data were correlated to the coals` slurryability which is characterized by the solid load at the viscosity of 1000 mPa.s and 25{degrees}C. 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, increase a little for the 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.
