The high-temperature fan mainly consists of an impeller, casing, air inlet, motor, connector, and cooling fan blades.
The impeller is a multi-bladed, single-inlet centrifugal impeller made of high-quality galvanized steel or cold-rolled steel. The blades are designed based on aerodynamic principles. The impeller consists of 10 backward-curved airfoil blades, a curved front plate, and a flat rear plate. It is made of high-strength, durable, high-quality steel and undergoes rigorous dynamic and static balancing. It has excellent aerodynamic performance, high efficiency, and stable operation.
The air inlet adopts a convergent streamlined anti-vortex design, resulting in minimal airflow loss and high operating efficiency.
The high-temperature fan casing and motor are connected by a metal casting. Cooling fan blades are installed on the motor shaft. Inlet and outlet water pipe interfaces are provided on the outer wall of the metal casting to cool the metal casting and shaft, ensuring normal motor operation at high temperatures.
Its motor uses a special high-temperature motor, and the fluid part of the high-temperature fan uses heat-resistant materials, ensuring reliable cooling structure performance. Compared with other boiler induced draft fans, it has advantages such as simple structure, convenient maintenance, and high cost performance.
