as main fans for mine ventilation systems while the axial type is favoured for underground locations. In this chapter, we shall define fan pressures and examine some of the basic theory of fan design, the results of combining fans in series and parallel configurations, the theory of fan testing and booster fan installations. 10.2. FAN PRESSURES

process, including the preheater ID fan, raw mill fan, baghouse ID fan, coal mill fans, finish mill fans and clinker cooler fans. This discussion is only intended to be an overview of possibilities for improving the operation and efficiency of mechanical draft fans. It …

Radial fans are industrial workhorses because of their high static pressures (upto 1400 mm WC) and ability to handle heavily contaminated airstreams. Because of their simple design, radial fans are well suited for high temperatures and medium blade tip speeds. Forward-curved fans are used in clean environments and operate at lower temperatures.

determined to be .643 by using the fan's operating altitude and temperature. Divide the design SP by the air density correction factor. 1.5" SP/.643 = 2.33" SP Referring to the fan's performance rating table, it is determined that the fan must operate at 976 RPM to develop the desired 7500
