The induced draft fan in waste incineration power plants is a key and high-end equipment specifically designed to cope with the harsh flue gas environment featuring high temperature, high corrosion, high abrasion, and high toxicity. Its remarkable features are reflected in the application of special materials (corrosion-resistant and wear-resistant alloys/coatings), multiple efficient seals (especially gas seals), variable frequency speed control, anti-fouling design, as well as high reliability and a comprehensive monitoring and maintenance system.

These features ensure that the induced draft fan can operate reliably under extreme conditions, guaranteeing the safe, stable, and environmentally friendly operation of waste incineration power plants. Its investment and maintenance costs account for a considerable proportion in the entire power plant, and its performance directly affects the overall operation efficiency and compliance with environmental emission standards. The fan impeller has a curved front plate and single-plate backward blades, featuring high efficiency, low noise, large static pressure, and a wide performance adjustment range.
