Abstract
The invention relates to a method for increasing the capacity of a waste-heat boiler (1) processing gases obtained from a metallurgic smelting furnace, such as a flash smelting furnace, and for reducing dust accretions, where liquid is added into the waste-heat boiler (1) of the smelting furnace. The invention also relates to an apparatus for increasing the capacity of a waste-heat boiler (1) processing gases obtained from a metallurgic smelting furnace, such as a flash smelting furnace, and for reducing dust accretions, in which case the waste-heat boiler is provided with at least one nozzle (2) for adding liquid.
Claims1
An apparatus for increasing the capacity of a waste-heat boiler processing gases obtained from a metallurgic smelting furnace, and for reducing dust accretions, wherein the apparatus comprises a waste-heat boiler, an uptake shaft of the smelting furnace, wherein a wall of the uptake shaft is provided with one nozzle for adding liquid into the uptake shaft of the smelting furnace, a radiation chamber, a convection chamber, and at least one nozzle which is
- arranged to inject liquid into a first end of the radiation chamber of the waste-heat boiler and
- placed in an essentially inclined position with respect to the gas flow entering from the smelting furnace to the radiation chamber.
