Abstract

A method of cleaning dryer exhaust gases during the drying of wood chips, wood fibers and the like is described in which at least one part of the dryer exhaust gases is filtered at a temperature lying above its dew point. At least one part of the particles which are filtered out in this way is conveyed, together with flushing air which likewise has a temperature above the dew point, substantially continuously into a combustion chamber and is burned there for hot gas generation.
