Description
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.
Key Advantages
- Impeller–It consists of blades, curved front plates and straight back plates. All these parts are made of steel plates. The impeller has passed static and dynamic balance correction and thus enjoy good aerodynamic performance, high efficiency, low noise and stable operating.
- Fans are generally equipped with air dampers to adjust their air capacity so that the air capacity and pressure meet the boilers’ optimal operating status.
- Driving system-The driving system consists of main shaft, bearing box and belt pulley. The main shaft is made of quality steel and the bearing is rolling bearing. The bearing box has enough capacity inside for cooling oil and is equipped with oil level indicator to ensure normal blower operation.

Application
They are applicable to normal temperature and hot gas, clean and dusty gas, powder materials and tiny granules. They can apply into boilers, dust removal, de-nitration and desulfurization, cement, metallurgy, power generation, gas and material handling, smoke exhausting. It can also be customized according to special industries.
