3、d stability can not be sustained. Therefore, reasonable and uniform air distribution is important to guarantee the normal flow and stable and secure operation of fluidized bed. This design is mainly for air distribution of a small fluidized bed reactor, and were introduced a preliminary presentation
4、 for fluidized bed principle and industrial applications. Air distributor belongs to important component in fluidized bed. This unit is consists of wind room, air distributor and air caps. This design choices ordinary flat air distributor and mushroom-type air caps. Calculating is necessary for the design. The purpose of this design catches the basic knowledge of fluidization and fluidized bed, and masters the method of the test equipment design through the fluidized bed reactor design of air d
