Publication number: 20210254860Abstract: A burner for use with an igniter for firing a flame into a heat-exchanger includes a body having a sidewall that defines an interior chamber. A first opening in the body receives a pre-mixed mixture of air and fuel. A second opening in the body is in fluid communication with the first opening. A distributor is connected to the body and closes the second opening. The distributor includes a first portion and at least one curved second portion provided on the first portion. Each second portion includes a plurality of first perforations in fluid communication with the first opening in the body. The first perforations of one second portion are positioned adjacent to the igniter such that ignition of the pre-mix mixture flowing through the first perforations results in a flame through the second portion. A flange extends around the first portion and includes second perforations.Type: ApplicationFiled: February 16, 2021Publication date: August 19, 2021Inventors: Michael J. O'Donnell, Richard Maricic

Patent number: 6478577Abstract: A burner nozzle includes a burner tube that extends along a central axis and has an inlet end portion for receiving combustible gas and air. The burner tube extends along the central axis from the inlet end portion to an outlet end portion for releasing a mixture of gas and air. A curved head with a plurality of openings and an imperforate portion is connected to the outlet end portion. The openings and imperforate portion of the curved head create a transverse flow of gas and air out of the curved head to produce a shaped flame. A burner assembly may include a combustion tube in which the burner nozzle is disposed and connected. The burner nozzle is used in a method of widening and shaping a flame.Type: GrantFiled: August 24, 2000Date of Patent: November 12, 2002Assignee: Beckett Gas, Inc.Inventors: Richard Maricic, Thomas F. Hutchinson, Jr.

Patent number: 6267586Abstract: The inventive burner can receive air and fuel and discharge a fuel/air mixture for combustion at a periphery of the burner while limiting NOx emissions. The burner has a central axis and includes first and second plates constructed and arranged so as to form between them a central chamber and a plurality of burner ports extending outwardly of the chamber. The first and second plates have an outer periphery spaced outwardly from the central axis. The second plate indudes an opening for receiving the air and fuel into the chamber. The outer periphery of the second plate extends from the central axis by a greater distance than the outer periphery of the first plate. The second plate has an outer peripheral portion in which a plurality of openings may be formed. Also included is a method for operating the burner so as to limit NOx emissions.Type: GrantFiled: May 5, 2000Date of Patent: July 31, 2001Assignee: Beckett Gas, Inc.Inventor: Richard Maricic

Patent number: 6190163Abstract: A burner nozzle includes a burner tube that extends along a central axis and has an inlet end portion for receiving combustible gas and air. At least one body or chamber has a passageway in communication with the burner tube along the central axis which leads to an elongated outlet end portion. At least one flame-shaping opening is located adjacent the outlet end portion. Each flame-shaping opening may be constructed and arranged effective to elongate (broaden the width of) flame resulting from combustion of the mixture transverse to the central axis to produce efficient heat transfer between the flame and air inside a heat-receiving member disposed downstream of the outlet opening. A flame length reducing member may be used instead of or in addition to the flame-shaping opening and the flame shaping opening may itself reduce flame length. A burner assembly may include a combustion tube in which the burner nozzle is disposed and connected.Type: GrantFiled: February 24, 1999Date of Patent: February 20, 2001Assignee: Beckett Gas, Inc.Inventors: Richard Maricic, Thomas F. Hutchinson, Jr.
