Fluidization plate, also known as pulverized coal tank fluidization plate, consists of stainless steel sintered filter mesh, fixed frame and flange.
Stainless steel sintered filter mesh is constructed of multiple layers of metal woven mesh after laminating, pressing and vacuum sintering. Square weave wire mesh is generally adopted as the filtration layer to enhance the open area, air permeability and filtration precision of the fluidization plate. Stainless steel sintered filter mesh is also provided with a stainless steel fixed frame to improve its mechanical strength and rigidity, and extend the lifespan of the fluidization plate.
The pulverized coal in the pulverized coal tank flows towards the injection tank under gravity. At that time, the compressed nitrogen gas blows the flowing down pulverized coal through the pores of the fluidization plate, keeps it fluidizing and the pulverized coal particles are separated from each other. The fluidity of pulverized coal increases consequently to prevent the pulverized coal from caking, lumping and bridging in the injection tank. And then it is conveyed to the distributor through the lower outlet to the coal injection system of the blast furnace.
Fluidization plates are divided into bottom fluidization plates and top fluidization plates by the installation position.

Top fluidization plate
We offer fluidization plates in a variety of diameters ranging from 300 mm to 3000 mm to suit to different fluidized bed. Typically, large diameter fluidization plates are directly welded to the fluidized bed while small diameter fluidization plates are fixed to the fluidized bed by tightening the flange.
