Axial type smoke pump DOD

A smoke blower is a draught blowing machine designed to move flue and other gases or dust-air mixture.
Draught blower - rotating vane machine, transferring mechanical energy of gas in one or more impellers, thus causing a continuous flow of gas at its maximum relative compression, and designed to move the medium in the gas-air path of boiler and other technological installations.
Axial draught blower - a draught blower with the direction of meridional velocity of gas flow at the inlet and outlet of the impeller parallel to the axis of its rotation.
DOD - Two-stage draught blowing machine - a draught blowing machine with several impellers, the design of which provides the possibility of passing the gas flow sequentially through all the wheels.
Flue gases - gases formed by combustion of organic substances with dust content up to 2 g/m3..
