ABSTRACT:
A method and a burner for combustion in a heating furnace of a fuel with an oxidant in the form of oxygen gas, wherein fuel and oxidant are supplied to a burner head. Fuel and oxidant, respectively, are injected via the burner head through at least two pairs of nozzles, wherein one nozzle pair is defined by a separate fuel nozzle and a separate oxidant nozzle. The nozzles of the nozzle pairs are uniformly distributed over the furnace-interior-facing surface of the burner and within the circumference of the burner head. An oxidant nozzle is provided on each side of a fuel nozzle.
