(57) Abstract:
The invention relates to an apparatus for feeding finely divided
solids, containing at least sulphidic metal concentrate, and
oxygenous oxidizing gas into a suspension smelting furnace, said
apparatus comprising elements for conducting solids and
oxidizing gas into the suspension smelting furnace. According to
the invention, in the feed office (7) of the suspension smelting
furnace through which solids (2) and oxidizing gas (3) are fed into
the action chamber (1) of the suspension smelting furnace, there is
installed a suspension creation chamber (5, 11) for a suspension
containing solids (2) and at least part of the oxidizing gas (3) can
be mixed to form a suspension before they flow into the reaction
chamber (1) of the suspension smelting furnace.
