ABSTRACT:
A gas burner comprises an elongated tubular body with a sidewall which has outer end edges between which there are apertures which pass through the sidewall; a flange with a central through hole and an opposite base cap, the sidewall, flange and base cap being attached to one another in such a way that together they define a first mixing chamber, in which a flow of gas and air, received through the flange, exits the tubular body through the apertures in the sidewall; the flange and base cap having opposite guides; the sidewall being wound in a spiral and having juxtaposed longitudinal edges with fluid tight seals and outer end edges inserted in the guides with a play designed to allow the perimeter of the sidewall to expand or contract according to changes in the temperature of the body.
