<p>6Method for incinerating carbon-containing dry metallic ashAbstractSThe invention relates to a method for incinerating carbon-containing dry metallic ash and a per tinent device. The method comprises the following steps:10adding the metallic ash into a trough;aerating with ambient air from above, and concurrently, at least for part of the time,injecting air and/or oxygen through the trough hearth;establishing the ignition temperature; 15 e) stirring of the metallic ash by means of a suitable tool;f) whereby the carbon content is reduced to less than 3%; andwhereby 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;20 and whereby the reverse transport of ash through the trough hearth is prevented, whereasthe supply of air and/or oxygen is maintained.Figure 1</p> |
