<p>A high efficiency exhauster (12) which is capable of attaining operating efficiencies of up to 70 % when employed in a solid fuel pulverizer firing system (10) that includes a pulverizer (16) which is operative to effect the pulverization therewithin of the solid fuel supplied thereto and a furnace (14) into which the pulverized solid fuel is injected for combustion therewithin. The high efficiency exhauster (12) includes a casing (46), an inlet ring (58) supported on the casing (46), a rotor (60) mounted on the casing (46) for rotation therewithin, a multiplicity of blades (72), each of a preestablished length and width, mounted in spaced relation one to another on the circumference of rotor (60) so as to extend at a preestablished angle, and an outlet (74) formed in the casing (46).</p> |
