A liquid fuel burner (10) is provided with a central fuel outlet (18) having a generally divergent conical inner surface, formed of two contiguous divergent conical surfaces (20a, 20b) of different angles of divergence, and a plurality of oxygen outlets (22) shaped and positioned for creating a converging, rotating stream of oxygen which intersects with any liquid fuel issuing from the fuel outlet (18). Such oxygen/fuel interaction results in two zones of combustion and a recirculation effect which assists in the complete or substantially complete combustion of undesirable exhaust gas components. The oxygen and fuel are preferably supplied such that their velocities are approximately equal at the point at which the two zones of combustion meet. |
