Skanska makes asphalt of wood powder
During the winter PetroBio on behalf of Skanska, upgraded the asphalt plant in Önnestad to use wood powder as the main fuel instead of LPG previously used.
The work begun in the autumn when two wood powder silos was built. During winter stop PetroBio then completed the rebuild. The burner has been replaced and the outer fuel management is in place. The entire delivery is controlled with a new control system.
Skanska can now use 100% wood powder as fuel in the burner's entire control range (4-12 MW). Needed more power, they can add another 4MW of gas, up to a total of 16MW.
