Product Introduction

Product Introduction:
The 6-51 boiler induced draft fan is mainly used in the forced and induced draft fan systems for steam boilers ranging from 2t/h to 670t/h in thermal power plants. It also meets the performance parameters required for high-pressure fluidized bed boilers. This series of fans can also be used for dust collection, mine ventilation, and general ventilation systems. The medium transported by the forced draft fan is air, while the induced draft fan transports flue gas or gases containing impurity particles. The fan can be used for more than four years when the impurity concentration is below 200mg/m³. If the impurity concentration is higher, the service life will be shorter. The maximum operating temperature for the forced and induced draft fans is 250°C. It features high efficiency, low noise, and a wide performance range.

Product Features:

①The fan design is based on aerodynamic models developed over more than a year of testing, utilizing advanced proprietary technologies such as high-strength, wear-resistant impellers and oil-leakage-proof bearing housings.

②The fan operates efficiently across a wide range of working conditions, with closely spaced machine sizes for easy selection of high-efficiency operating points.

③High-strength, wear-resistant impeller.

④The fan is available in either integrated or split assembly configurations.

⑤Complete set of components available.

⑥Full range of relevant parameters provided.

⑦The fan is easy to install and maintain.
