1、 The purpose of the fan

G. The Y6-41 boiler centrifugal drum and induced draft fan are a new series of low-noise boiler drums and induced draft fans designed to adapt to industrial boilers that use various coal qualities and are equipped with dust and smoke elimination devices, with a maximum total pressure efficiency of over 80%. Those with similar inlet conditions and suitable performance can be selected.
2、 Characteristics of the fan
G. The Y6-41 series centrifugal fan is a replacement product for boiler drums and induced draft fans.
G. The design method used for the Y6-41 series ventilation fan includes selecting appropriate fan types, reasonable fan operating parameters, optimizing flow patterns, organizing air sources reasonably, carefully designing blade shapes, increasing tongue clearances, appropriately reducing fan speeds, improving volute design, purifying incoming flow, and minimizing secondary flow losses. In addition, the finite difference method is used to numerically calculate the inlet and impeller cover profiles, and the uniformity of the flow field at the inlet of the fan impeller is used as an optimization criterion for the inlet optimization design. Combine the above methods with existing optimization design methods for fan impellers, volutes, etc. to create an integrated optimization design program for impellers, volutes, and air inlets, with lower specific noise levels and smaller fan sizes.
G. The Y6-41 series ventilation fan has been tested by Shenyang Blower Research Institute and achieved good results. The test data is excerpted as follows:
Induced draft fan: Y6-41-11 No.7.1C with 4 tons/hour coal-fired boiler:
Working temperature: 200 ℃; Speed 2100 RPM
Design operating condition parameters: flow rate: 12500 m3/h; Full pressure: 2596 Pa
