Provided is a burner with a central 
fuel supply arrangement (27), an annular 
air channel (17) surrounding the central 
fuel supply arrangement (27) for supplying 
combustion air, and swirl vanes (19) disposed in the annular 
air channel (17). The swirl vanes (19) have first gas nozzles (21) for injecting a gaseous fuel into the 
combustion air, and second gas nozzles (23) for injecting a gaseous fuel into the 
combustion air. The first gas nozzles (21) are fed from a first gas distribution channel (29) in the 
fuel supply arrangement (27), and the second gas nozzles (23) are fed from a second gas distribution channel (31) in the fuel supply arrangement (27). The first gas distribution channel (29) and the second gas distribution channel (31) are supplied with combustion gas from a 
gas supply pipe (41) which has a first 
gas supply channel (35) and a second 
gas supply channel (37), the first gas supply channel (35) being connected to the first gas distribution channel (29) and the second gas supply channel (37) being connected to the second gas distribution channel (31).
