YX9-35 Induced Draft Fan for Boilers
The many series of boilers, big quality difference for fuel coal as well as the adding of dust removal system and surplus heat utilization equipment might cause insufficient blower sucking capacity, positive pressure to the furnace and other problems, affecting boilers’ fuel burning and normal operation. To avoid this, YUTONG designed different models of induced draft fans for boilers meeting boilers’ air capacity and air pressure.

To avoid this, YUTONG designed different models of induced draft fans for boilers meeting boilers’ air capacity and air pressure.
Key Advantage:
1. Impellers- They are composed of 16 front curved blades made of Q345 (16Mn). After impellers are formed, the fineness of dynamic balancing is no more than Grade 5.6, so impellers enjoy stable and reliable operation, high strength and anti-wear ability and long service life.
2. Air inlet- With convergent and streamlined integrated design, the air inlet is fixed with screws by front cover plate set to the side plates of blower casing inlet.
3. Driving system-The driving system consists of main shaft, and bearing box, etc. The main shaft is made of quality steel. Blowers with No. 6.3C and lower numbers use fan blade for cooling; blowers with No. upper than 6.3C use bearing boxes with pure-bronze cooling pipes inside. The water consumption for lubrication oil for cooling is generally considered as 0.5-1m3/h. The bearing box is equipped with thermometer and oil level indicator. The oil amount to be added shall be based on the oil level indicator.
