Modelling of slurry droplet drying
The drying often takes place in spray dryers (Fig. 1) where the gas and slurry streams are brought into contact. One of the most important industrial applications of slurry drying is the use of sub-bituminous coal in power generation. This low-rank coal contains roughly 30% moisture in its as-mined state.
Coal Slurry
The classifier cut size can be adjusted to yield the require fineness. This is an efficient process but requires drying of coal; the grinding system and certainly the powdered coal storage should be blanketed by inert gas for safety reason. Wet grinding is simpler and appears to be the preferred method for slurry fuel preparation.
