Hot blowing fan VGD-SD

The centrifugal hot blast fan of right and left rotation, designed for recirculation of hot air from boilers of power plants and other industrial plants at temperatures up to 400 ° C.The fan structurally consists of a guide apparatus, necessary to regulate the parameters of operation, 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 of 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.
