Custom variable frequency low noise boiler dust collector induced draft fan
The centrifugal fan uses a high-speed rotating impeller to accelerate the gas, then
decelerates and changes the flow direction to convert the kinetic energy into potential
energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from
the axial direction, changes radial as the gas flows through the impeller, and then
enters the diffuser. In the diffuser, the gas changes the direction of flow and the
increase in the section area of the pipe slows down the gas flow, which converts
kinetic energy into pressure energy. * The pressure increase mainly occurs in the
impeller, followed by the diffusion process. In a multistage centrifugal fan, a reflow
is used to make the air flow into the next blade to produce a higher pressure.
