Fan D-K

The centrifugal fan of right and left rotation is designed to supply air to the furnaces of stationary steam and hot-water boilers. The fan can also be used in other installations of various industries with similar performance indicators. The fan structurally consists of a guide apparatus, necessary for regulating 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 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.
