Canada-based Norbord, an international producer of wood-based panels, will be relocating their press from its factory in Alberta, Canada, to Inverness, Scotland, along with an order of an OSB dryer with energy plant.

The single-path drum dryer from Siempelkamp subsidiary, Büttner, sized 6.5 x 36 R will have a throughput capacity for dry strands of 45 t/h along with the air process equipment, steel support structures and insulation. To top it off, the scope of delivery will also include a 500 m³ wet-material horizontal metering bin.

The energy plant with a total combustion capacity of 55 MW will use a 75 m² grate to generate around 40 MW of flue gas to heat the dryers, and 15 MW for heating thermal oil. For the drum dryer, Büttner will supply the entire range of equipment from moving floor for the fuel storage to the primary circulation system for thermal oil, which will include the piping, brick lining, steel construction, and insulation.

Part of Büttner’s scope of delivery too is the complete assembly of the dryer and energy plant, which is scheduled to be concluded by mid 2017.
