<p>For the purposes of the complete destruction, especially combustion, of carbon compounds like plastics, hydrocarbons, uncoated or coated paper, slurries and timber waste mixed with halogen-containing material like PVC, i.e. practically sorted domestic rubbish, the hydrocarbons are first mixed in a preliminary stage (7) with hot sand in a water vapour atmosphere, during which water gas is separated off. The degassed residue is taken with the now cooled sand to a fluidised bed combustion process and the gaseous fraction formed in the preliminary stage (7) is taken to a post-combustion process using the fluidised bed exhaust gas as the oxidizer. The hot exhaust gas produced can now be cooled in the ordinary way.</p> |
