Discharge Stability of Pulverized Coal from Bunker

The effects of the air make-up mode,the hopper structure and the filling height on discharge stability of pulverized coal from bunker were investigated.The percentage of cross sectional area for effective coal flow in the hopper is the most important factor affecting discharge steadily.Using one or more outlets,a steady mass flow takes place in a properly structured multi-outlet hopper with combination of air flux in the different aeration sections.The filling height has only a minor effect on the stability...
