Abstract
The system presented here allows saving around 10% of the thermal energy required in a wood chips drying process. The significant reduction of emission levels of approcimately 98% relating to total carbon is guaranteed by the integrated vapour treatment. Maximum emission reductions are obtained with high capacity utilization - thermal power - of the integrated vapour combustion unit. No additional downstream waste air purification units are necessary. Fresh water demand in the gluing process can be minimized by condensing the dryer vapours.
