BIOFIT Case Study: Conversion of the fossil oil boiler of Sölvesborgs Energi och Vatten in Sweden to the utilization of bio-oil

Together with project partner ESS, the utilization of bio-oil in the existing central heating boilers of Sölvesborgs Energi och Vatten in Sölvesborg, Sweden, will be investigated. The heating boilers have a capacity of 16 MW in total.

The main objective for this case study is to investigate the possibilities and prerequisites for converting from fossil oil to vegetable oil in the existing boilers at the case study company, and with two sub objectives: 1. To examine the market for available bio-oils and pyrolysis oils, and 2. To examine the prerequisites for adapting the system to also produce power via an Organic Rankine Cycle (ORC).

The investigation will act as a base for the case study company on a decision for investments. A consultant report will contribute to additional input to the base for the decision. The consultant focus on the prerequisites for converting from mineral oil to bio-oil for e.g. type of bio oil, need of new burner, need of new pipes, containers and other equipment and need of heat to keep the fuel warm.

ESS has accomplished three working group meetings with the  case study company, the last one together with the consultant.
