A feed mixture distribution device configured to even out a feed of feed mixture in an annular feed mixture feed channel of a burner. The feed mixture distribution device includes a cylindrical member having a cylindrical wall, a first end, a second end, and a longitudinal central axis X. The cylindrical member is at the first end provided with rectangular flat plate means, which extend radially from the cylindrical wall of the cylindrical member and which are arranged symmetrically about the longitudinal central axis X of the cylindrical member. The cylindrical wall of the cylindrical member is between the rectangular flat plate and the second end provided with helical plate means arranged symmetrically about the longitudinal central axis X of the cylindrical member.

Feed mixture distribution device

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.

Burner and fine solids feeding apparatus for a burner

The invention relates to a method of using a suspension smelting furnace and to a suspension smelting furnace and to a concentrate burner (). The concentrate burner () comprises a first gas supply device () for feeding a first gas () into the reaction shaft () and a second gas supply device () for feeding a second gas () into the reaction shaft (). The first gas supply device () comprises a first annular discharge opening (), which which is arranged concentrically with the mouth () of a feeder pipe (), so that the first annular discharge opening () surrounds the feeder pipe (). The second gas supply device () comprises a second annular discharge opening (), which is arranged concentrically with the mouth () of the feeder pipe (), so that the second annular discharge opening () surrounds the feeder pipe () opening ().
