First, the use of fans
G, Y6-41 boiler centrifugal drum. Induced draft fan , Is to adapt to various coal burning with smoke and dust means the elimination of industrial boilers designed for maximum total pressure efficiency higher than 80% of the new series of low noise boiler drum, Fan, Where the inlet conditions can be quite the performance but also - adaptation can be selected.
Second, the characteristics of the fan
G, Y6-41 series centrifugal fan, boiler drums, Fan replacement.
Design Method G, Y6-41 series fan you are using: select the appropriate type of fan, fan reasonable working parameters, preferably flow type, rational organization of the gas source, well-designed airfoil, increasing wind tongue gap, due to lower fan speed, improve volute design, purification to flow and minimize secondary flow losses, such as design principle, combined with the use of finite difference method numerical machine inlet and impeller-type wire wheel covers, and the fan impeller inlet flow field uniformity as to optimize sentence It has been designed to optimize air intake. The method described above combined with the original fan impeller, volute and other optimization method integrated into the impeller, volute, the air inlet of the three integrated design process optimization, lower than the noise level and a smaller fan size.
G; Y6-41 series of fans has been tested and Shenyang Blower Research Institute; achieved good results; the test data quote is as follows:
Induced draft fan: Y6-41-11№7.1C with 4 t / h coal-fired boilers:
Working temperature: 200 ℃; speed of 2100 rev / min
Design working parameters: Flow: 12,500 m 3 / hour; total pressure: 2596 Pa
