Abstract

An apparatus to be used in connection with a circulating fluidized bed reactor 1 for separating solid material from the flue gases and for recycling the solid material to the reactor comprises two adjacent, mainly horizontal, concentric vortex chambers 2 and 10 of different sizes that have discharge openings 5 and 8 concentric with the vortex chambers. The vortex chamber 2 having a greater diameter is connected with the reactor via a gas inlet duct 3 that is tangentially connected with the vortex chamber. The vortex chamber 10 having a smaller diameter is equipped with a gas inlet concentric with the vortex chamber, which inlet is connected with the gas discharge opening 5 in the larger vortex chamber 2. The return ducts 6 and 11 for the separated solid material are connected with openings on the periphery of the vortex chamber. <IMAGE>
