Advanced CFB for Clean and Efficient Coal Power

The European Union's Clefco project (2004-06) aimed to promote the development of once through steam cycle (OTSC) CFB technology. This was carried out by increasing the process knowledge that is essential for successful boiler design and demonstration of the multi-fuel flexibility of the process. To fulfil the development needs of OTSC CFB technology, a comprehensive understanding of CFB combustion processes needed to be achieved. Intensive research in laboratory, pilot and full-scale combustors was required to fulfil the abovementioned objectives. In the project, each partner worked in its own field of research. Cooperation between partners enabled the best-possible understanding of the process.
