Method for combustion of a fuel using an existing air burner (1), which air burner (1) comprises a first supply opening (5) for fuel and a second supply opening (7) for air, which supply openings (5,7) open out into a combustion zone (3). The invention is characterised in that a gaseous fuel with an LHV (Lower Heating Value) of less than 7,5 MJ/Nm 3 is supplied through the second supply opening (7), in that an oxidant comprising at least 85 percentages by weight oxygen is also supplied to the combustion zone (3) through a supply device for oxidant, and in that the gaseous fuel is caused to be combusted with the oxidant in the combustion zone (3). |
