The disclosure relates to a method of generating a powerfully oxidizing flame, and a burner therefore, the burner including a central body (9) with a central oxygen nozzle (23) and at least one fuel nozzle (25, 26), a casing (1) surrounding the central body (9), at least one peripheral oxygen nozzle (13) radially outside the fuel nozzle (25, 26), and an oxygen chamber (21) outside the central body (9), all nozzles (23; 25, 26; 13) being at least substantially parallel. The central oxygen nozzle (23) and the peripheral oxygen nozzle (13) are connected to different sources of oxygen, it being possible for the source connected to the central oxygen nozzle (23) to deliver a higher pressure than the other source. Preferably, the central oxygen nozzle (23) is designed as a laval nozzle. When solely oxygen is supplied to the burner, it may be employed as an oxygen lance. Preferably, oxygen is then only supplied to the central oxygen nozzle (23). |
