High Flow High Efficiency High Quality Carbon Steel Steam Boiler Ventilation Fan
Product Description:
The boiler centrifugal fans are designed to enable the induced fans to work in the high-efficiency zone when the industrial boilers are operating under variable conditions, so as to achieve the purpose of energy saving. The high-efficiency and energy-saving products jointly designed by famous experts in the industry and promoted by the State Economic Commission and the Ministry of Machinery Industry have the advantages of high, efficient low noise, and a wide high-efficiency zone of the performance curve.
This fan is suitable for a 0.5-35t/h industrial boiler equipped with an economizer (preheater) and smoke and dust removal device. The maximum inlet temperature shall not exceed 250°C. A dust removal device with a dust removal efficiency of not less than 85% must be installed in front of the induced draft fan to reduce the dust content of the flue gas entering the fan, which not only reduces the environmental pollution of the flue gas but also reduces the Air wear on the fan is beneficial to improve the service life of the fan.
Structural features:
The fan is composed of an impeller, casing, air inlet, transmission group, regulating door, and other components:
1. The impeller material is forward curved blades with alternate lengths and short lengths. After the impeller is formed, it is corrected by static and dynamic balance, so the operation is stable and reliable.
2. The casing is welded into a volute casing with steel plates. A dust-cleaning door is opened on the snail plate. It is convenient to remove the dust accumulated in the blade and the casing and ensure the balance and aerodynamic performance of the impeller.
3. The air inlet is made into a convergent and streamlined overall structure, which is fixed with bolts and the front cover plate.
4. The transmission group consists of a main shaft, a water-cooled bearing box, and a coupling. The main shaft is made of high-quality steel. Rolling bearings are used, and the bearing housing has two forms: integral type and partial type.
5. The adjusting door is a device used to adjust the flow rate of the fan. The adjusting door blades are petal-shaped and axially installed in front of the air inlet. Due to the adoption of the external transmission structure, the rotation is flexible and convenient.
