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.

Patent number: 8021143Abstract: A gas fired furnace capable of operating with a 16:1 turndown ratio or greater. The furnace includes a plurality of burners (10) grouped into at least (14a) first and second (14b) groups, each group connected to a source of combustible gas through a control valve (30a, 30b, 30c). The control valve (30c) controlling at least one group of burners is of a modulating type having an output proportional to a control signal applied to the valve. The burners fire into associated heat exchange tubes (20a), each tube having an inlet (24) and an outlet. The tube outlets are connected to a collector chamber (44) that includes a baffle plate (60) that divides the collector into two sections, one of the sections communicating with the outlets of the tubes associated with the first group of burners, the other section communicating with the outlets of the heat exchanger tubes associated with the other group of burners.Type: GrantFiled: November 19, 2010Date of Patent: September 20, 2011Assignee: Beckett Gas, Inc.Inventor: Terrance C.

Publication number: 20100258280Abstract: A heat exchanger apparatus includes at least one single piece tubular member that has a normal radius and a generally circular cross section and a restricting and turbulating structure. The structure includes at least one opposing pair of obstructions that are exposed to one another and have a generally parabolic dimple shape disposed within the tubular member. The tubular member extends along a longitudinal axis. The length of each obstruction extends parallel to the longitudinal axis such that the obstructions extend parallel to one another. At least one of the obstructions projects into the tubular member to form a dead flow area between the obstructions through which fluid flow is negligible. A pair of adjacent converging, diverging nozzles is separated by the dead flow area, each having an aperture through which a fluid may flow and maintain the normal radius of the tubular member.Type: ApplicationFiled: June 24, 2010Publication date: October 14, 2010Inventors: Michael J.

Patent number: 7255155Abstract: 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 and provide a pair of converging, diverging flow nozzles to promote turbulence of the flue gases. The turbulence characteristics of the tube can be controlled by varying the size of the aperture of the nozzles. In certain applications, the dimples are located along the sides of the heat exchanger tube, thereby providing unobstructed drainage for liquids even when the tube is bent into a serpentine shape.Type: GrantFiled: November 25, 2003Date of Patent: August 14, 2007Assignee: Beckett Gas, Inc.Inventors: Michael J.

Patent number: 6916174Abstract: A burner having an elongate, generally tubular sheet metal body having an inlet end, a closed distal end and a tubular segment extending between the ends. The inlet end is formed to define a gas orifice holder which is adapted to mount a gas orifice element. The inlet end is further formed to define at least one primary air opening arranged to admit primary air from a source of primary air. Rows of flame ports are defined in the tubular segment and are arranged to create a desired predetermined flame pattern. When used as a fireplace burner the flame ports may be slot-like in construction and include tabs which determine the effective size of the ports. In a fireplace application, flame ports located below a crossover log, are eliminated and/or formed of reduced size, thus providing a flame of lower height and/or less intensity, thus substantially eliminating sooting.Type: GrantFiled: March 6, 2002Date of Patent: July 12, 2005Assignee: Beckett Gas, Inc.Inventors: Michael J.

Patent number: 4559594Abstract: Electrostatic air cleaner apparatus is disclosed for use in conjunction with existing space conditioning apparatus which includes a transformer providing a low voltage (typically 24VAC) power signal. The apparatus includes a power supply which is adapted to be coupled to the output of the transformer for providing a low voltage DC power signal. A high voltage generator and regulator is included which is powered by the low voltage DC power signal. The generator and regulator includes a flyback transformer arrangement which generates a high voltage DC signal suitable for energizing the collector and ionizer stages of an air cleaner assembly. The generator and regulator also includes closed loop feedback for regulating the amplitude of the high voltage DC signal so that it remains at or near the optimum amplitude regardless of variations in the amplitude of the low voltage power signal supplied by the existing low voltage transformer.Type: GrantFiled: November 25, 1983Date of Patent: December 17, 1985Assignee: Adams Manufacturing CompanyInventors: Lawrence M.
