boiler drought fan

This boiler drought fan is a Y5-48 boiler centrifugal induced draft fan, which is used to burn various fuels and 1t / h ~ 20t / h industrial boilers, and is equipped with smoke and dust proof devices. The maximum temperature of the medium it handles generally does not exceed 250 °C. A dust control device must be added to the front of the induced draft fan to reduce the dust content of the flue gas entering the fan.
Product description

Product introduction:

This boiler drought fan is a Y5-48 boiler centrifugal induced draft fan, which is used to burn various fuels and 1t / h ~ 20t / h industrial boilers, and is equipped with smoke and dust proof devices. The maximum temperature of the medium it handles generally does not exceed 250 °C. A dust control device must be added to the front of the induced draft fan to reduce the dust content of the flue gas entering the fan.

Product features:

1. At present, there are many industrial boiler series. The quality of coal combustion varies greatly. The resistance of the dust collector is different, and the air volume and air volume required by the fan are also very different. In order to adapt to the above situation, considering the economics of the fan, a belt (C type) gear is used.

2. The series of boiler drought fans consists of an impeller, a casing, an air inlet, a damper and a drive unit. The impeller has 12 rear plate blades welded between the conical cover and the flat plate to ensure smooth operation after static and dynamic balancing. It has higher strength and resistance to vibration and wear.

3. Boiler drought fan's rolling plate is provided with a dustproof door to remove dust deposits on the blade and inside the casing. The adjustment door of the shock absorber is petal-shaped, with No. 4 to 6.3 being 9 pieces and No. 8 or more being 11 pieces. The axial installation is in front of the air inlet, and the drive is flexible and convenient due to the external drive mode. The adjustment range is from 0° (full open) to 90° (fully closed). In order for all components of the regulating gate to function properly, the lubrication must be good. Lubricating with molybdenum disulfide high temperature (260 ° C) must be used.

Performance and selection:
The dimensional performance curve is converted with non-dimensional performance curve. The converting formula is as follows:

When the conditions of service are inconsistent with the designated country, the performance of the non-designated country must be converted to the performance of the designated country. The conversion formula is:

The normal pipe network characteristic equation is known: P = KQ 2, if the actual value k is less than the theoretical value k, the flow rate increases; and vice versa, the flow rate decreases, see Fig.3.
