Abstract: The present invention provides a burner capable of recovering more reliably a flame going out at one flame port via the transfer of flames from other flame ports when the burner is turned down. The burner according to the present invention is formed of two metal plates 10, 20 having substantially wave-shaped ends and superposed with the wave phases shifted. The burner comprises plural flame ports 12, 22 vertically alternately disposed along the ends of the metal plates 10, 20, and plural gas channels 14, 24 for supplying gas to the flame ports 12, 22. The burner further has a first deformed portion 16 where one metal plate 10 is deformed toward the other metal plate 20 at the flame port portions of one of the upper and lower flame ports 12, 22.

Abstract: A burner capable of reducing manufacturing costs by attaching upper and lower flow regulating plates to a metal plate rationally from the viewpoint of costs is provided. A burner 100 comprises a metal plate, having formed thereto a plurality of flame ports 102 disposed along the inner circumference of an opening 101 and alternately protruding in the upper and lower directions, and an annular mixture pipe 106 disposed outwardly of the opening 101. Substantially annular upper and lower flow regulating plates 200 and 300 are respectively disposed above and below the burner 100 with a clearance therebetween. The burner 100 has an integrally disposed flange portion 120 extending outwardly from the annular mixture pipe 106.
