Application

The XY9-35-12 Series Industrial Boiler Induced Draft Fan is designed to overcome the challenges of insufficient suction caused by varying coal quality and the addition of dust removal and waste heat recovery equipment in modern boilers. This Centrifugal Fan provides high-efficiency airflow and pressure management, ensuring stable combustion and smooth boiler operation. The fan can be configured as either a right-handed or left-handed unit. Viewed from the motor end, a clockwise impeller rotation denotes a right-handed fan ("right"), while a counterclockwise rotation indicates a left-handed fan ("left"). The fan's outlet angle can be configured to 0°, 90°, 180°, or 45°, 135°, 225°, and 270° for specific installation needs. When placing an order, customers must specify both the rotation direction and the desired outlet angle. The fan uses a C-type transmission mode, which allows for easy adjustment of the main shaft speed and performance.
 

Structural Characteristics

• 1. Impeller Design: The impeller is constructed from a series of forward-curved blades welded to a curved front disc and a flat rear disc, all made from high-quality steel. The impeller undergoes rigorous testing for overspeed and dynamic balancing to ensure optimal performance with low noise and stable operation.
• 2. Casing Construction: The casing is made from heavy-duty welded steel plates, forming a robust spiral structure. This design enhances durability and provides resistance against high temperatures and operational stress.
• 3. Regulating Door: The regulating door enables precise control of airflow and pressure, ensuring the fan operates at the most efficient levels for any boiler application.
• 4. Transmission Assembly: The main shaft is manufactured from premium-grade steel and uses rolling bearings. The bearing box is designed to accommodate cooling oil, and an oil level indicator is included to facilitate safe and reliable operation under varying environmental conditions.
