Oxygen Carrier Aided Combustion for more efficient fuel conversion in FB plants with simultaneous recovery of alkali compounds
Research Project , 2018 – 2021

In this project, the goal is to investigate, develop and contribute to the commercialization of the recently demonstrated oxygen-carrier aided combustion (OCAC) concept. The OCAC is unique as it can be implemented directly in existing fluid bed boilers to optimize the conversion and flexibility of fuel, enable recovery of alkali from the fuel ash, reduce the consumption of virgin sand and reduce the amount of ash formed. The innovative technology proposed here, with the right conditions for development, can revolutionize the heat and power industry with regard to lower environmental impact and reduced operating and maintenance costs. The primary potential is to create resource-efficient use of supplied fuel, lower amount of, in the long term, higher electricity efficiency in boilers. The researchers behind the innovation can, through this project, contribute to new knowledge in fluid beds, and take the international research front for FB and active bed materials a big step forward.
