ARRANGEMENT FOR EVENING OUT POWDERY SOLID MATTER FEED OF A CONCENTRATE BURNER OF A SUSPENSION SMELTING OR SUSPENSION CONVERTING FURNACE

摘要

The object of the invention is an arrangement for feeding powdery solid matter into a concentrate burner (2) of a suspension smelting or suspension converting furnace (1). The concentrate burner (2) comprises reaction gas feeding means (6), powdery solid matter feeding means (3) and a concentrate distributor (7). The arrangement comprises a first powdery solid matter discharge pipe (8) for feeding powdery solid matter into the powdery solid matter feeding means (3) of the concentrate burner (2). The first powdery solid matter discharge pipe (8) is provided with a first partition (10), which divides solid matter, for dividing the first powdery solid matter discharge pipe (8) into two essentially similar discharge pipe parts (11). The powdery solid matter feeding means (3) of the concentrate burner (2) comprise an annular concentrate discharge channel (4) that surrounds the concentrate distributor (7) of the concentrate burner. Each discharge pipe part (11) of the first powdery solid matter discharge pipe (8) is at least partly divided into two discharge pipe portions (12) by a second partition (13).
