摘要：
The invention relates to a method of using a suspension smelting furnace and to a suspension smelting furnace and to a concentrate burner (4). The concentrate burner (4) comprises a first gas supply device (12) for feeding a first gas (5) into the reaction shaft (2) and a second gas supply device (18) for feeding a second gas (16) into the reaction shaft (2). The first gas supply device (12) comprises a first annular discharge opening (14), which which is arranged concentrically with the mouth (8) of a feeder pipe (7), so that the first annular discharge opening (14) surrounds the feeder pipe (7). The second gas supply device (18) comprises a second annular discharge opening (17), which is arranged concentrically with the mouth (8) of the feeder pipe (7), so that the second annular discharge opening (17) surrounds the feeder pipe (7) opening (14).
