Abstract

A method and a burner for combusting fuel with oxygen, the fuel being delivered to a combustion zone from a center exit nozzle (5). Oxygen travelling at low speed is delivered from a first oxygen nozzle (3) at a first radial distance from the center fuel jet, and oxygen travelling at high speed is delivered from a second oxygen nozzle (6) at a second, greater radial distance from the center fuel jet. This results in incomplete combustion of the fuel with the oxygen moving at low speed in a first region, and incomplete combustion with the oxygen moving at high speed in a second region downstream of the first region, these regions together forming the combustion zone.
