Abstract:
1. A filter device for separating dust from flue gases in combustion plants, comprising: a dust filter positioned along the flue gas path, the dust filter comprising: wherein when the flue gas flows through the bulk material filter, heat from the flue gas is absorbed by the bulk material filter, and wherein when combustion air from the combustion plant flows through the bulk material filter, the bulk material filter heat is released to the combustion air, in which the bulk material filter has a bulk material dedusting device, the dedusting device adapted to separate the dust from the bulk material, wherein the bulk material dedusting device has a lower collecting tank arranged in the flue gas flow direction downstream of a first material lock of the bulk material dedusting device, from which tank the bulk material dust mixture can be routed by a conveying airflow to a cyclone separator in which the bulk material and the dust can be separated from each other.
