characterised by the arrangement of separation apparatus, e.g. cyclones, for separating particles from the flue gases

Apparatus in which combustion takes place in a fluidised bed of fuel or other particles > with means specially adapted for achieving or promoting a circulating movement of particles within the bed or for a recirculation of particles entrained from the bed > the particles being circulated to a section, e.g. a heat-exchange section or a return duct, at least partially shielded from the combustion zone, before being reintroduced into the combustion zone > characterised by the arrangement of separation apparatus, e.g. cyclones, for separating particles from the flue gases
