A dual oxidant burner having an inner conduit (14) with a passage communicating with a source of fuel, an outer conduit (12) over the inner conduit and an intermediate conduit (20) between the inner (14) and outer (12) conduits. The three conduits (12,14,20) form an inner passage (26) between the inner (14) and intermediate (20) conduits communicating with a source of oxygen, and an outer passage (24) between the intermediate (20) and outer (12) conduits communicating with a source of air. The fuel and the two oxidants are mixed in a furnace or other combustion zone beyond the outlet of the nozzle (16) and the two passages (24,26) and their flow amounts are individually adjusted to establish the burner flame. <IMAGE> |
