AKJ Energiteknik has built the boiler plant that is now used as a reserve and peak load power in Vänersborg. The plant was commissioned during the fall. Performance with good emission values. We at AKJ thank Vattenfall for a fun project, professional leadership and all partners for your strong commitment.

The district heating network in Vänersborg is approx. 160 GWh and is mainly supplied with waste heat from the Vargön Alloys smelter. Vargön Alloys produces ferroalloys for stainless steel and the process generates large amounts of excess heat that is recovered via exhaust gas boilers connected to the district heating network. The new pellet-fired plant is used when waste heat is not available or sufficient.

AKJ Energiteknik is building a new energy center with 18MW 30bar steam boiler for Moelven Vänerply. Moelven is one of Europe's largest manufacturers of sawn timber. Moelven Vänerply is located in Otterbäcken, four miles north of Mariestad, and manufactures plywood from spruce and pine. Each year, about 90,000 m3 or about 6 million m2 of plywood is produced. The plywood is manufactured by heating debarked logs through basing and then turning them into veneer, which is then dried. The drying process is energy-intensive and the residues from production in the form of bark, shavings and chips are used as fuel.

The bef energy center was built in 1969 and will now be replaced with a new modern steam plant. The contract includes earthworks and foundations, concrete and construction works for a new boiler house and fuel storage, fuel conveyors, incinerator, boiler, flue gas cleaning with electric filter, mechanical and electrical installations, control system, back-up boiler, and new steam and feedwater system.
