摘要
三种Geldart-D颗料在 2 1m长的料斗 -立管系统中悬料状态的初始条件的实验已研究表明 :初始悬料区时 ,气体的压力梯度与料斗中颗粒的静态高度和孔板的孔口直径无关 。
The incipient condition of hung-up regime for three Geldart-D powders has been experimentally studied in a 21m long standpipe and hopper system.Experimental results show that the pressure gradient at the incipient hung-up state is independent of the stagnant height in the hopper and the diameter of orifices,while correspondingly gas velocity in the standpipe can be predicted by Kwauk's equation.
