<p>The invention relates to a method for incinerating carbon-containing dry metallic ash and a pertinent device. The method comprises the following steps: a) adding the metallic ash into a trough; b) aerating with ambient air from above, and concurrently, at least for part of the time, c) injecting air and/or oxygen through the trough hearth; d) establishing the ignition temperature; e) stirring of the metallic ash by means of a suitable tool; f) whereby the carbon content is reduced to less than 3%; and whereby steps b), c), and d) can proceed concurrently or in alternating order or pairs or all of these steps can proceed concurrently; step d) can just as well proceed selectively in partial quantities of the metallic ash; and whereby the reverse transport of ash through the trough hearth is prevented, whereas the supply of air and/or oxygen is maintained.</p> |
