9-38 high-pressure centrifugal fan is to make the industrial boiler in the variable operating conditions, the induced wind function in the efficient area of work, to achieve the purpose of energy saving, by the Ministry of Machinery Industry fan energy-saving group, the organization of the national fan industry joint design, the State Economic Commission And the Ministry of Machinery Industry focus on promoting the efficient energy-saving products, with high efficiency, low noise, high performance curve of the advantages of high suburbs.
The fan is suitable for equipped with economizer (preheater) and smoke and dust removal device 0.5 ~ 35t / h industrial boiler selection. Where the intake conditions are similar, performance and adapt to those who can be used, but the maximum intake air temperature should not exceed 250 ℃.
In the induced draft fan must be installed before the dust removal efficiency of not less than 85% of the dust removal device to reduce the smoke into the fan dust, reduce the dust on the fan wear and improve the life of the fan.
