A new biomass boiler plant at UPM Joensuu Plywood Mill in Finland has improved the facility’s energy efficiency, environmental performance and safety.
The plant utilises wood waste from plywood production and has resulted in lower fuel consumption per heat output and lower emissions compared with the previous power plant. The flue gases from combustion pass through the electrostatic precipitator and flue gas scrubber after heat recovery.
It is hoped the new plant will also boost the efficiency of the veneer drying line at the plywood mill. According to UPM Plywood, thermal energy plays an important role in the multi-stage plywood production process and is needed for veneer drying and hot-pressing of plywood boards, as well as for heating the log-soaking pond.
