The prototype has already been burning BtL from wood for some time.
During the development phase, Benninghoven equipped the asphalt mixing plant of the Swedish road construction company Asfaltbolaget Sverige AB with an EVO JET multi-fuel burner with BtL capability. As BtL fuel is relatively viscous, it is first heated to processing temperature and then transported in heated and insulated pipes. Asfaltbolaget relies on BtL produced from wood. This renewable energy source is supported and promoted by the Swedish state.
By using this innovative energy source, Asfaltbolaget demonstrates its focus on the future and its will to improve. “We want to move forward. The innovative technologies from the Wirtgen Group are an important contribution towards this. They help us to work efficiently and achieve high-quality results. And with BtL fuel, we have found a great option of running an even cleaner operation”, explains Production Manager Patrik Magnusson.
Benninghoven helps with the burner configuration for BtL
In the case of Asfaltbolaget, the challenge of this process lies in the wood as a natural raw material, which has a varying chemical composition. These fluctuations affect the BtL end product. This would normally result in more work for the operator, as the burner parameters would have to be continuously adapted.
The customer therefore sends their heating medium to Germany in a stainless steel container so the correct basic parameters for the burner can be configured at the Benninghoven factory. Benninghoven tests the fuel and sets up the burner with the optimum parameters so the values can be adopted directly on site in Furuby in southwest Sweden.
