Patent number: 9161660Abstract: A deep fryer apparatus including a gas burner for heating cooking oil. The burner includes a venturi inlet for receiving fuel and combustion air that communicates with a main chamber having an expanding cross-section. A balancing plate is disposed in a flow path of the fuel air mixture that is located intermediate the inlet and the outlet. The balancing plate defines a region of reduced cross-section in the flow path. A flame cap located at the outlet defines at least one secondary chamber between itself and the balancing plate that defines a flow path cross-section that is larger than the cross-section of the flow path at the balancing plate. The balancing plate is preferably tapered to compensate for variations in the length of the flow path due to an angled orientation between the burner inlet and the outlet.Type: GrantFiled: July 30, 2008Date of Patent: October 20, 2015Assignee: Beckett Gas, Inc.Inventors: Michael J.

Patent number: 9068761Abstract: A gas burner including a burner body having a lower housing, an inlet conduit and a combustion surface element attached to the lower housing. A diffuser/reflector positioned within the body encourages even distribution and mixing of a combustible gas/air mixture. The diffuser/reflector is preferably of a sheet metal construction and includes a plurality of stamped openings with each of these openings having an overhanging guide plate. The combustion surface element includes a plurality of integrally formed rigidizing ribs and is made from a high temperature steel alloy wire cloth. The inlet conduit is secured directly or indirectly to an access door/bulkhead that is used to close off an access opening formed in a water heater wall through which the burner is installed. In one construction, an air scoop shrouds the inlet conduit and at least partially defines a flow path of primary air, substantially isolated from the combustion chamber.Type: GrantFiled: September 28, 2012Date of Patent: June 30, 2015Assignee: Beckett Gas, Inc.Inventors: Michael J.

Publication number: 20140190178Abstract: A combustion method and combustor for use in a jet engine, the jet engine having a compressor portion and a turbine portion. The combustor includes an outer tube having a central axis that extends longitudinally intermediate the compressor portion and turbine portion and is positioned to receive air discharged by the compressor portion. An inner tube is positioned within the outer tube that includes an associated outer surface spaced from the inner surface of the outer tube thereby defining a combustion chamber. The outer tube and inner tube include fluid directing structure for communicating at least some of the air discharged by the compressor portion to the combustion chamber. The fluid directing structure directs air into the combustion chamber in a direction offset from the central axis, thereby causing rotation or swirling of the air about the central axis.Type: ApplicationFiled: August 10, 2012Publication date: July 10, 2014Applicant: BECKETT GAS, INC.Inventor: Michael J.

Patent number: 8459342Abstract: A heat exchanger tube having an integral restricting and turbulating structure consisting of dimples formed by confronting indentations pressed into the sides of the heat exchanger tube. The dimples are comprised of indentations disposed in pairs which extend into the tube to such a depth as is necessary to significantly reduce the cross sectional area of the heat exchanger tube. The dimples of a pair are staggered or offset, longitudinally with respect to each other such that a restrictive passage is defined between each pair of offset dimples. The turbulence characteristics of the tube can be controlled by varying the depth to which the dimples project into the tube and the longitudinal spacing between the dimples that comprise the pair. Adjacent pairs of dimples may be rotated 90° with respect to each other or alternately can be arranged in a helix pattern.Type: GrantFiled: August 10, 2007Date of Patent: June 11, 2013Assignee: Beckett Gas, Inc.Inventors: Michael J.
