What is the differential pressure of the material layer of the circulating fluidized bed boiler?

　　The material layer differential pressure of circulating fluidized bed boiler is also called material layer resistance, which corresponds to a certain fluidized air volume and material layer thickness. When the fluidized medium passes through the material particle layer supported above the air distribution plate, it will move along the height direction of the material layer and generate flow resistance.

　　The material layer differential pressure is a physical quantity that characterizes the height of the fluidized bed material layer, and a certain material layer height corresponds to a certain material layer differential pressure. In the fully fluidized state, the differential pressure of the material layer of the circulating fluidized bed boiler is the same as the gravity of the fluidized material on the air distribution plate per unit area and the buoyancy above the air distribution plate of the fluidized bed is basically the same.
