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