Reuse of bed material from fluidized bed boilers

The project aims to improve methods for regenerations of bed sand in fluidized bed boilers to reduce the usage of virgin bed sand. Today a large share of the bed sand is exhausted after use, due to agglomeration between sand and ash, and has to be deposited. The project is relevant for the reserach program (RE:Source) and has potential to decrease the use of virgin raw material.
