Abstract (en)

A burner (6) comprises a front frame (20) of sheet metal forming a front opening (22), a rear frame (24) of sheet metal different from the front frame (20) and forming one or more rear openings (25) overlapped with the front opening (22) of the front frame (20), a diffuser (4) sandwiched and retained between the front (20) and rear (24) frames, in which the front (20) and rear (24) frames are connected to each other by means of a mechanical fastening without welding (for example, by means of tox-clinching) in a plurality of mutually spaced discrete connection positions (26), in which the diffuser (4) extends at least partially around the connection positions (26) and has recesses (27) at the connection positions (26), so that the mechanical fastening without welding (e.g. tox-clinching) involves only the two sheet metals of the front (20) and rear (24) frames, but not also the diffuser (4).
