The present invention deals with an oxygen aspirator burner (1) and a process for firing a furnace with an oxygen-enriched oxidant gas. The process and apparatus for firing a furnace using oxygen or oxygen-enriched air as the oxidant gas, comprises injection into the furnace of a plurality of oxidant jets (8), through nozzles (4), in a spaced relationship to a fuel jet (9), at a velocity sufficient to cause aspiration of furnace gases into the oxidant jets before the latter mix with the fuel jet, in amounts sufficient to lower flame temperature. |
