An apparatus for use in a circulating fluidized bed reactor for separating solid material from the flue gases and for recirculating the solid material to the reactor. The apparatus comprises a duct for directing the flue gases from the reactor slantingly downwards to a return duct adapted to return a part of the flues laden with solid particles back to the reactor. At a point of entry of particle laden gases into the return duct, a deflecting wall diverts a major portion of the gases to the inlet of a vortex separator. The separator chamber has a discharge opening concentrical with its generally horizontal axis, for discharge of flues from which solid particles have been removed. |
