Abstract

A burner and a method utilize a burner tile with an outer surface extending along the furnace wall and an inner surface defining a passageway. A fuel duct extends at least partially through the passageway and discharges fuel onto a burner head. The burner head forms a coanda-curved surface, wherein the fuel is directed onto the coanda-curved surface such that the fuel flows along the coanda-curved surface to the outer surface of the burner tile. There is an air channel defined by an outside edge of the coanda-curved surface and in fluid flow communication with the passageway such that air flows from the passageway through the channel to mix with the fuel so as to produce the combustible mixture.
