ABSTRACT:
The location of an air supply in a combustion apparatus is made adjustable by changing the point of intersection of a slot in a movable surface with a slot in a fixed surface. In the preferred embodiment, the fixed and movable surfaces are of tubular construction. Variations include a second movable surface for the purpose of extending the range of adjustment, and the use of discrete holes rather than slots in the fixed and movable surfaces.
