Abstract
A first reactor includes a circulating fluidized-bed rector with a reaction space of an axially annular cross section, and the second reactor includes a circulating fluidized-bed reactor surrounding the first reactor in a symmetrically concentric fashion, whereby also the second reactor has a reaction space of an axially annular cross section. The construction according to the invention makes it possible to implement also large equipment with a small height-to-diameter ratio, whereby the footprint/space requirements of the equipment are minimized and problems associated with thermal expansion are reduced essentially.
