According to the relationship between bed pressure drop and operating gas velocity,minimum spout-fluidizing gas velocity was obtained. Fluidizing gas can minimize thespouting gas velocity, but it results in an increase in minimum spout-fluidizing velocity.
根据床层压降与表观气速(喷动气和流化气之和)的关系图，可得到最小喷动(流化)速度，流化气的引入可减小喷动气气速，利于喷动，但使最小喷动流化速度增大。
