Abstract
A concentrate burner of a suspension smelting or suspension converting furnace includes a reaction gas feed, a powdery solid matter feed and a concentrate distributor. An arrangement for feeding powdery solid matter to the concentrate burner includes a first powdery solid matter discharge pipe for feeding powdery solid matter into the powdery solid matter feed of the concentrate burner. The first powdery solid matter discharge pipe is provided with a first partition, which divides solid matter, for dividing the first powdery solid matter discharge pipe into two essentially similar discharge pipe parts. The powdery solid matter feed of the concentrate burner comprise an annular concentrate discharge channel that surrounds the concentrate distributor of the concentrate burner. Each discharge pipe part of the first powdery solid matter discharge pipe is at least partly divided into two discharge pipe portions by a second partition.
