5-51 series fluidized bed boiler/dust removal system fan

1、 Fan form:

The air volume of the 5-51 series centrifugal induced draft fan is 2470-377586 ㎥/h, the air pressure is 1567-5764Pa, and the power is 15kw-2000kw. The ventilation fan and induced draft fan are single suction, with 21 machine numbers ranging from No. 8F to 31.5F each.To learn more, click to consult(To provide you with a cost-effective solution).

2、 Details introduction:

Suitable for the feed system of 2-670t/h steam boilers in thermal power plants, it also meets the requirements of high pressure head performance parameters for fluidized bed boilers. This series of fans can also be used for dust removal, mine ventilation, and general ventilation systems. The supply fan delivers air, while the induced draft fan delivers smoke or gas containing impurities. When the impurity concentration is less than 200mg/m3, it can be used for more than four years. If it contains high impurities, it can also be used, but the service life will be shortened. The operating temperature of the induced draft fan shall not exceed 250 ℃. The performance of a fan is represented by parameters such as flow rate, total pressure, spindle speed, shaft power, and efficiency.

3、 Product features:

(1) Impeller: It consists of 12 angled blades welded to the middle of the conical front plate and the flat rear plate. Due to the use of wing shaped blades, the fan ensures high efficiency, low noise, and high strength. The impeller has undergone static and dynamic balance correction, ensuring smooth operation. The impeller structure of the ventilation and induced draft fans with the same machine number is the same. (2) Shell: The shell is a snail shaped body welded from ordinary steel plates. The casing of a single suction fan is made in three different forms: the casing of No. 8-12 is made into a whole structure and cannot be disassembled. The shell of No. 14-16 is made into two open types. The shell of No. 18-29.5 is designed as a three open type. The induced draft fan and volute plate have been appropriately thickened to prevent wear and tear. (3) Air inlet: The convergent and streamlined air inlet is made into a whole structure and fixed to the inlet side of the fan with bolts. (4) Regulating door: a device used to regulate the flow rate of a fan, installed axially in front of the air inlet. The adjustment range is from 0 ° (fully open) to 90 ° (fully closed). (5) Transmission part: The main shaft of the transmission part is made of high-quality steel, and this fan adopts rolling bearings. There are two forms of bearing housings: for № 8~16, integral cylindrical bearing housings are used; Use two independent pillow type bearing housings for No.18-29.5. The bearing box is equipped with a thermometer and an oil level indicator (only for the induced draft fan). The lubricating oil used is No. 30 mechanical oil, and the oil level is implemented according to the oil level mark. When using dry oil for the integral cylindrical bearing box of No. 8-16, an oil baffle should be added on the ball side of the bearing box, and the mutual communication of its fixing groove should be made. The induced draft fan is equipped with a water cooling device, so a water supply pipe must be installed. The water consumption varies with temperature and is generally considered to be 0.5-1m3/h.
