Abstract
An afterburner positionable adjacent the discharge end of a combustion chamber of a fuel-burning heater utilizes a ring portion and a nose cone portion which are constructed as a unit out of a single piece of material. The ring portion accommodates the attachment of the afterburner adjacent the discharge end of the combustion chamber, and the nose cone portion has a skirt including peripheral edge portions which are spaced from and overlap the inner edge portions of the ring portion so that the direction of movement of the flow of products of combustion through the combustion chamber is altered before the combustion products exit the chamber. The afterburner is formed from a single piece of sheet steel in steps involving a first press operation, a lancing operation, and then a second press operation.
