Abstract
An air nozzle for introducing secondary air into a furnace and including a housing provided with an inlet at one end thereof for receiving air and an outlet at the other end thereof for discharging the air. A damper is disposed in the housing in the path of the air for splitting the flow of the air into two flow streams which extend to different areas of the furnace and is adapted for pivotal movement in the housing to vary the amount of air flow in each of the streams and the discharge angle of one of the streams.
Claims3
In combination, a furnace comprising at least one wall;
- and an air nozzle comprising a housing having an inlet for receiving air and an outlet for discharging the air, a mounting member for mounting the housing to the at least one wall of the furnace for pivotal movement about a first axis to vary the air discharge pattern from the outlet so that the air is discharged into the interior of the furnace in a variable discharge pattern, and a damper blade mounted in the housing about a second axis extending transversely to the first axis for splitting the discharging air into two streams.
