Abstract: 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.

Abstract: Provided are a burner such as a concentrate burner, a calcine burner, or a matte burner, or a burner using a mixture of these for feeding reaction gas and fine solids into a reaction shaft of a suspension smelting furnace, and a fine solids feeding apparatus for a burner such as a concentrate burner, a calcine burner, or a matte burner, or a burner using a mixture of these. The fine solids feeding apparatus comprises gas outlets in a fine solids discharge channel upstream of a downstream outlet end of the fine solids discharge channel. The gas outlets comprise spiral path guiding members configured to facilitate gas to flow from the gas outlets in a spiral flow path around a center axis A of the fine solids discharge channel.
