Since the nineties, our research team has been exerting efforts to solve the energy and building industry problems of handling and processing solid residues from the fluidized bed combustion (FBC) technologies.
In many areas worldwide one can meet with depositions of low grade coal or coal waste (slurry) which were either neglected due to the state-of-the-art of energy generation technique by its shipment costs or simply for environmental aspects. This is the case of the Limburg Area, the Lorraine Area, the Upper Silesian Basin to name only some.
Fresh wind of the world energy crisis in the seventies attracted the attention to the forgotten energy depositions with a goal to develop technologies to make the most from the least. The FBC installations meet the goal, moreover, the reduction of SOx and NOx is another evident feature. The addition of SO2 sorbent at the combustion process gives rise to larger amount of solid residues to be handled, deposited or better utilized than it is in case of conventional coal boilers.
