Abstract: The invention relates to a gas burner for burning fuel gases with oxygen, said gas burner comprising a primary gas nozzle (6) and secondary gas nozzles (5) which are connected to a common central feed line (3). In this case, the non-horizontal openings (8), directed obliquely downwards, of the primary gas nozzle are oriented in such a way that the gas jet of said primary gas nozzle is directed towards a point of a centre line (10) between two respective secondary gas nozzles, and the centre line is defined as an imaginary line which runs parallel to the rotation axis of the primary gas nozzle and centrally between two adjacent secondary gas nozzles.
