M7-29 Coal Powder ModelCentrifugal FanThe design is tailored to the performance requirements of a thermal power plant boiler coal powder combustion system. It is used to blow coal powder into the boiler; the coal powder cannot pass directly through the impeller, as it would cause excessive wear. The volute is lined with protective plates for easy replacement after wear. The bearing housing contains lubricating oil for bearing cooling, and is equipped with cooling water pipes to cool the lubricating oil.
