Biowarme Klein St. Power Plant, Austria
Process Drying
Background At the central district heating company in Karnten, Austria, shredded wood and bark is burned as the fuel. The wood that is delivered to the plant by farmers is often wet, and therefore, not suitable for a fire. An efficient method for drying the wood was required. Solution A SolarWall® air collector was installed on the south roof of the drying facility. Mounted at a 45º angle, preheated air is drawn through the 100 m2 surface into the building. The floor of the drying facility is covered by air channels, which are in turn covered by perforated metal. The solar heated air is funneled from the roof through ducts onto the drying bed. The wood is stored on the floor over the hot air, and is dried prior to burning.
Results The solar air collector has generated very positive results at the power plant. The fans have a capacity of 7200m3/hour, and the solar radiation can produce drying tempera-tures in excess of 60ºC.
