Abstract

The invention relates to a method for incinerating carbon-containing dry metallic ash and a pertinent device. The method comprises the steps of

p) adding the metallic ash into a trough;q) aerating with ambient air from above, and concurrently, at least for part of the time,r) injecting air and/or oxygen through the trough hearth;s) establishing the ignition temperature;t) stirring of the metallic ash by means of a suitable tool;u) 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;and whereby the reverse transport of ash through the trough hearth is prevented, whereas the supply of air and/or oxygen is maintained.
