Fans and blowers provide air for ventilation and industrial process requirements. Fans generate a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other com-ponents in a fan system. The fan rotor receives energy from a rotating shaft and transmits it to the air. Difference between Fans, Blowers and Compressors

Axial fans, as the name implies, move an airstream along the axis of the fan. The air is pressurized by the aerodynamic lift generated by the fan blades, much like a propeller and an airplane wing. Although they can sometimes be used interchange-ably with centrifugal fans, axial fans are commonly used in "clean air," low-pressure, high-volume

2009 12 30 Three primary air fans were in operation one for each pulverizer Each mill was supplied with one seal air fan which takes suction from atmosphere and supplies seal air to coal mills for sealing system i.e preventing the pressurized dust coal from coming out of the mill The superheater steam system had mainly three sections.

Since the selected unit burns coal with high coal moisture all the year round, the outlet temperature of the mill is difficult to reach its design value of 65 °C. Therefore, in general, the hot air valve of the coal mill is kept fully open, while the cold air valve is basically closed.

pressurized seal air is also used to prevent leakage of coal dust from the mill and to protect bearings in the grinding rollers. MILL SYSTEM COMPARISON AND PERFORMANCE Refer to Table I for a summary of the design features for each mill system. Mill Comparisons—General The BTM is a low-speed mill that primarily grinds coal by impact and ...

Coal from travelling belt of raw coal feeder drops in central feed pipe ( connection between Raw Coal Feeder and Mill). After coal reaches Mill bowl grinding started and hot air also been given to make the pulverised fuel dried enough to classifier chamber. The portion of the coal which cannot be grinded finds its way to mill reject.

The main reason for using seal air in bowl mill is to prevent escape of pulverised coal from the mill A second function that seal air performs is that it cools the lubricating oil being used for the bearings of the rollers used to pulverise the coal.
