Abstract
The gas burner comprises a mixer, a conical transition member adjacent thereto on which a cylindrical burner shell with openings and whose top is closed by a burner lid is mounted. Clamped between the burner lid and the transition member is a throttling cylinder which is filled by the super-stoichiometric gas mixture at super-atmospheric pressure. In order to avoid burner pulsations the cylinder has throttling openings whose total area is 2 to 10% of the total area of the openings. The throttling openings are in a plurality of circular rows above one another in such a manner that they are on a respective vertical line. Vertical, imperforate sections of the burner shell are opposed to the lines so that the mixture jets from the throttling openings do not impinge directly on the openings. The cylinder is provided at a coaxial spacing of 5 mm from the burner shell.
