dense powder
2.Under the different agitating velocity and agitator vertical location,the effect of agitator on the feed powder characteristics and the fluidizing stability of system was analyzed in dense phase pulverized coal pneumatic conveying,the new correlations of different parameters with average feed powder rate and bed pressure standard deviation were established,the optimal operation and geometrical parameters were provided with 90 r/min agitating velocity and location of +25 mm comparative to powder outlet.
