Patent number: 10371377Abstract: A burner assembly combines oxygen and fuel to produce a flame. The burner assembly includes an oxygen supply tube adapted to receive a stream of oxygen and a solid fuel conduit arranged to extend through the oxygen tube to convey a stream of fluidized, pulverized, solid fuel into a flame chamber. Oxygen flowing through the oxygen supply tube passes generally tangentially through a first set of oxygen-injection holes formed in the solid fuel conduit and off-tangentially from a second set of oxygen-injection holes formed in the solid fuel conduit and then mixes with fluidized, pulverized, solid fuel passing through the solid fuel conduit to create an oxygen-fuel mixture in a downstream portion of the solid fuel conduit. This mixture is discharged into a flame chamber and ignited in the flame chamber to produce a flame.Type: GrantFiled: August 17, 2017Date of Patent: August 6, 2019Assignee: Honeywell International Inc.Inventors: Curtis Taylor, Brad Patterson, Jayson Perdue

Patent number: 9982885Abstract: Devices, methods, and systems for utilizing a burner with a combustion air driven jet pump are described herein. One burner apparatus includes a jet pump located inside a burner housing, the jet pump having a combustion air inlet that receives combustion air, a chamber to receive the combustion air from the combustion air inlet, and a tapered portion of the chamber that tapers to an outlet having a smaller diameter than the diameter of the inlet.Type: GrantFiled: June 16, 2015Date of Patent: May 29, 2018Assignee: Honeywell International Inc.Inventors: Curtis L. Taylor, Joseph S. F. Goh, Brad Patterson, Marek Scholler

Patent number: 9939151Abstract: A nozzle in a burner assembly is configured to produce a flame. The nozzle is configured to include a fuel-discharge outlet and to conduct fuel along a path in the nozzle to the fuel-discharge outlet. Pressurized primary oxygen is provided to mix with fuel discharged by the nozzle to produce a mixture that can be ignited to produce a flame. Staged oxygen is provided to the flame in a region downstream from the nozzle.Type: GrantFiled: March 15, 2013Date of Patent: April 10, 2018Assignee: Honeywell International Inc.Inventors: Curtis L. Taylor, Brad Patterson, Marek Scholler

Patent number: 9851099Abstract: According to the present disclosure, a flat-flame nozzle is provided for producing a flat flame in a flame chamber included in a burner assembly. The flat-flame nozzle is configured to conduct fuel from a fuel supply to an ignition zone in the flame chamber. In some illustrative embodiments, the flat-flame nozzle is also configured to conduct oxygen from an oxygen supply to the ignition zone to produce a combustible oxygen-fuel mixture in the flame chamber. In illustrative embodiments, a removable first plate-separation border frame is positioned to lie between a first lower plate and a companion first upper plate. This border frame is configured to cooperate with those plates to form in the flat-flame nozzle a fuel-discharge outlet and a fuel-transport passageway communicating with the fuel-discharge outlet.Type: GrantFiled: March 5, 2013Date of Patent: December 26, 2017Assignee: Honeywell International Inc.Inventors: Curtis L. Taylor, Brad Patterson, Tracy Fine, Jayson Perdue
