Overview

G5-51/Y5-51 type steam furnace supply fan boiler induced draft fan is suitable for the supply and induced draft fan system of 2t/h~670t/h steam boilers in thermal power plants, and can also meet the performance parameters of high pressure heads in fluidized bed furnaces. This series of fans can also be used for dust removal, mine ventilation, and general ventilation systems. The medium conveyed by the air supply fan is air, while the medium conveyed by the induced draft fan is flue gas or gas containing impurity particles. When the impurity concentration is less than 200mg/m2, it can be used for more than four years. If the impurity concentration is high, it can also be used, but the service life is relatively shortened. The maximum operating temperature of the pantograph induced draft fan should not exceed 250 ℃.

Product Details

G5-51/Y5-51 type steam furnace air supply fan boiler induced draft fanUsually made in single suction form. Organic numbers Na8D-29.5D each have 20 machine numbers, totaling 40 specifications. Each type of fan can be made into two types: left-handed or right-handed. When viewed from one end of the motor, any fan whose impeller rotates clockwise is called a right-handed cyclone fan, represented by "right", and vice versa, is called a left-handed cyclone fan, represented by "left". The position of the air outlet of the fan is represented by the angle of the outlet of the casing. The transmission mode of the fan is D-type, which is a cantilever structure. The connection between the motor and the fan adopts elastic coupling direct transmission.The design of this series of fans is based on the aerodynamic sketch that has been finalized through more than a year of model testing, and adopts the technology of "adjustable air inlet"Technique; A series of advanced proprietary technological achievements, including high-strength wear-resistant impellers, leak proof bearing housings, and self-aligning axial adjustment doors.When the diameter of the fan impeller is greater than 2m or the circumferential speed exceeds 100m/s, non-destructive testing shall be carried out according to the standard.When the impeller peripheral speed is high, reinforced blades are used, and the wear-resistant parts of the induced draft fan blades are welded with fan specific wear-resistant welding rods. After on-site wear, users can weld them themselves.
