Beschreibung
Zusammenfassung:	Provided is a burner such as a concentrate burner or a matte burner for feeding reaction gas and fine solids into a reaction shaft of a suspension smelting furnace. The burner comprises an annular fine solids discharge channel that is radially limited at the outside by a first annular wall and that is radially limited at the inside by a second annular wall. The annular fine solids discharge channel is configured to receive fine solids from a fine solids feeding arrangement and to create an annular flow of fine solids in the annular fine solids discharge channel. The annular fine solids discharge channel being provided with spreading means configured to be hit by the annular flow of fine solids and configured to even out particle distribution in the annular flow of fine solids.
