<p>Method and device for removing volatile organic components (VOC) from waste gases of a cement clinker kiln installation. Cooled waste gases are subjected to post-combustion carried out to an extent ensuring a concentration reduction of the VOC below admissible values. Post-combustion is carried out for production of vapor, dimensioned for a gas volume to be post-combusted, ensuring that a partial quantity of the waste gas corresponding to the gas volume allows for the reduction of emitted VOC per unit time in the waste gas below admissible concentration values by rarefaction. The partial quantity of the waste gas is simultaneously dimensioned for production of an amount of vapor sufficient for economical operation of a steam turbine. The device includes a branch line connected to a waste gas line between a pre-calciner and a waste gas suction fan, and a combustion chamber and a turbine connected to the branch line.</p> |
