ABSTRACT:
An air nozzle assembly for use in an associated combustion apparatus which includes a secondary air nozzle apparatus. The air nozzle apparatus may be a part of the windbox of an associated furnace. The apparatus includes a housing which has at least a part thereof disposed surrounding a first axis. The part has respective first second third and fourth cross-sectional areas at first, second, third and fourth axially spaced planes that are perpendicular to and axially spaced along the first axis of the part of the housing. The cross sectional area of each of the first second third and fourth cross-sectional areas each different from each other of the cross sectional areas. The apparatus also includes a diffuser member; apparatus for supporting the diffuser; and apparatus for moving the apparatus for supporting along a second axis, the second axis is parallel to the first axis.
