Abstract
A high efficiency exhauster which is capable of attaining operating efficiencies of up to 70% when employed in a solid fuel pulverizer firing system that includes a pulverizer which is operative to effect the pulverization therewithin of the solid fuel supplied thereto and a furnace into which the pulverized solid fuel is injected for combustion therewithin. The high efficiency exhauster includes a casing, an inlet ring supported on the casing, a rotor mounted on the casing for rotation therewithin, a multiplicity of blades, each of a preestablished length and width, mounted in spaced relation one to another on the circumference of the rotor so as to extend at a preestablished angle, and an outlet formed in the casing.
