Type 480 Industrail Boiler Used Multi Cyclone Dust

The flue gas flows into the dust filter in certain speed, and rotates in the cyclone tube through the director. Under the action of centrifugal force, the particle and the gas are separated. The dust after separation falls down on the hopper of the dust collector, and exports from bottom discharge valve.
