Industrial burner
First Claim
1. An industrial burner assembly comprising at least one elongated burner, wherein each said at least one elongated burner comprises:
- an outer mixing tube having a longitudinal axis;
an inner mixing tube positioned coaxially about said longitudinal axis at least partially within said outer mixing tube to form an annular space therebetween, said inner mixing tube having an inside surface and a plurality of apertures;
an outlet ring member having an inside surface defining a centrally-located opening, and a rear surface with a first seat portion in sealing engagement with a forward end of said inner mixing tube and a second seat portion in sealing engagement with a forward end of said outer mixing tube; and
an inlet ring member having an inside surface defining a centrally-located opening a rear surface, a forward surface with a first seat portion in sealing engagement with a rear end of said inner mixing tube and a second seat portion in sealing engagement with a rear end of said outer mixing tube, said inside surfaces of said inlet ring member, said inner mixing tube, and said outlet ring member being aligned to form a passage for air flow therethrough, and a port communicating with said annular space, wherein said port is in communication with a source of fuel such that said fuel can flow through said annular space and through said apertures into said passage to intermix with air flowing through said passage.

Abstract
An industrial burner assembly comprising a manifold with a fuel inlet and a longitudinal axis, and a plurality of elongated burners positioned radially about the longitudinal axis having fuel ports in communication with the manifold and fuel inlet, wherein each elongated burner has an outer mixing tube, an inner mixing tube positioned coaxially within the outer mixing tube to form an annular space therebetween in communication with the fuel port, the inner mixing tube having an inner surface forming a passage for air flow through the burner assembly, and a plurality of apertures formed in the inner mixing tube to allow introduction of fuel from the annular space into the air flow passage to provide for efficient mixture of air and fuel in the burner assembly prior to combustion.
