Air cowl is the key component of fluidized bed boiler to realize uniform air distribution and maintain reasonable gas-solid two-phase flow and operation in the boiler, which can make air distribution more uniform.
Features of boiler air cowl:
The small boiler air cowl is characterized by its small aperture and good air distribution uniformity, but the wear caused by its small design spacing is common. The big wind cap is characterized by its large aperture, large turbulence intensity after reaching the critical fluidization, and large design spacing, so it can effectively avoid wear caused by the opposite blowing of the wind cap, and thus has a long service life.
