Patent number: 10591157Abstract: A burner has a dual use pot whereby the pot can be machined to provide for single flow control to inner and outer flame rings (directly related to each other) as a single flow configuration or maintained in a dual flow configuration whereby a user can separately control flow to inner and outer flame rings (independently related to one another). A lateral passage is fed from an inlet to feed outer flames while a transverse passage possibly elevationally displaced from the transverse passage for some embodiments can feed the inner ring. The lateral and transverse passages are joined to be in fluid communication through the method taught herein.Type: GrantFiled: June 25, 2018Date of Patent: March 17, 2020Assignee: Burner Systems International, Inc.Inventor: Timothy L.

Patent number: 6428313Abstract: A burner having an elongated cylindrical body closed at one end with a plurality of ports spaced apart in two rows along the upper segment of the body, said ports formed by punching. The ports have an upper edge and a lower edge wherein the lower edge is displaced a first distance below the upper edge and a second distance beyond a vertical axis tangent to the upper edge. Accordingly, flames are emitted substantially sideways out of the cylindrical body and any drippings on the tube are directed away from the cavity of the cylindrical body.Type: GrantFiled: September 21, 2001Date of Patent: August 6, 2002Assignee: Burner Systems International, Inc.Inventors: Ian M. Rodgers, Gerry L. Shavers

Patent number: 6000934Abstract: An underfed burner has an elongated cylindrical body closed at both ends and a feed tube connected between the ends for feeding an air and gas fuel mixture into the burner through an entry portal. A pressure dispersing baffle is formed within the entry portal integral with the body of the burner and deflected downwardly into the interior of the burner. The baffle is in the form of two flaps supported by a rib integral with the body of the burner and extending across the entry portal. The baffle is formed by a die and a punch carried by the die. The die forms a depression about the opening created by the deflected baffles to define the portals and extends gradually longitudinally away from the flaps while the punch cuts the material to form the portal, the rib and the baffle flaps. A pair of mandrels enter the body of the burner from respective ends to provide support for the die and punch.Type: GrantFiled: January 26, 1999Date of Patent: December 14, 1999Assignee: Burner Systems International, Inc.Inventors: Gerry L. Shavers, Sherman D. Peed

Patent number: 5915954Abstract: An atmospheric, low emission gas burner within the combustion chamber of a hot water heater in which the combustion chamber is sealed against entry of air except for the air/gas mixture entering through the burner. The burner comprises a venturi through which gas and air enter and a diffuser disposed about the venturi, the diffuser and venturi constructed to take advantage of the high thermal buoyancy within the water heater. The burner operates at low manifold pressure and creates low emissions of NOx and CO. The burner diffuser has a multiplicity of small slots disposed on the upper surface which is covered by a course mesh fabric material having relatively large openings designed to keep the flame front above and off the diffuser while maintaining a stable flame that does not flashback.Type: GrantFiled: July 28, 1998Date of Patent: June 29, 1999Assignee: Burner Systems International, Inc.Inventor: Ian M. Rodgers

Patent number: 5762490Abstract: A premixed gas burner for use in a boiler or the like has a burner body including a distribution tube into which air under pressure and a gas fuel are received. The gas is supplied to the distribution tube through a gas supply orifice tube having a flange in the form of a disk disposed about the periphery of the gas supply tube and positioned a short distance within the distribution tube. The gas supply tube has a number of orifices located about the tube adjacent to the downstream facing surface of the flange. The distribution tube is located within a pressurized air chamber and gas supplied from a manifold to the supply tube is mixed turbulently adjacent the downstream face of the flange. The invention extends the operating range of premixed gas burners and reduces the carbon monoxide and NO.sub.x output of the burner.Type: GrantFiled: June 19, 1997Date of Patent: June 9, 1998Assignee: Burner Systems International, Inc.Inventor: Ian M.

Patent number: 5743727Abstract: A premixed gas burner has an elongated hollow burner body including a burner deck formed by a multiplicity of burner ports about a small sector of the body. The burner body is closed at one end and an elongated distribution tube is received within the body through and extending out the other end. The end of the distribution tube extending out of the burner body has an inlet into which a mixture of gas and air may enter, the opposite end of the distribution tube being closed. A series of directional ports formed between louvered slats adjacent the closed end and spaced from the inlet are formed along a small sector of the distribution tube and directs the mixture of gas and air back toward the inlet end. The sector of the distribution tube in which the ports are formed is substantially 180.degree. from the sector of the burner body in which the deck ports are formed.Type: GrantFiled: January 21, 1997Date of Patent: April 28, 1998Assignee: Burner Systems International, Inc.Inventor: Ian M.
