Gas recirculation smoke pump fan VGDN-19P with

The fan is a centrifugal draught blower of single-sided suction of right and left rotation, designed for recirculation of hot air from boilers of power plants and other industrial installations at temperatures up to 400 C in moderate climate (U). The fan structurally consists of a guide apparatus, necessary for regulating the operating parameters, spiral casing, impeller, which serves to transfer energy to the flow from the drive motor and running gear. In the process of medium movement in the impeller, the flow is dynamically influenced by the blades and is involved in rotational motion. This results in a change in the momentum of the transported medium and an increase in its potential and kinetic energy. The increase in flow energy is expressed as an increase in static and dynamic pressure.
