Overview of turbine induced draft fans:
The wind turbine is based on the principle that the kinetic energy is converted into potential energy, the gas is accelerated by the high speed rotating impeller, and then the speed is changed, the kinetic energy is converted into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, and the gas flows into the radial direction when the gas flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the flow direction and the area of the pipe section increases to slow down, which converts the kinetic energy into pressure energy. The increase of pressure mainly occurred in the impeller, followed by the expansion process. In the multi-stage centrifugal fan, the air flow is used to make the air flow into the next impeller, which leads to higher pressure.
Characteristics of turbine induced draft fans:
1 low loss, high efficiency;
2 high power factor;
3 inverter capacity is low.
