Circulating fluidized bed reactor for gas-solid reactions has a centrifugal separator and an integrated acceleration duct located in the upper part of the reaction chamber

摘要

A circulating fluidized bed reactor comprises a reaction chamber (1) connected by an acceleration duct to a centrifugal separator (2) for separation of particles from hot gases entering the reaction chamber. The acceleration duct is located partly in the upper part of the reaction chamber. Preferred Features: The acceleration duct can be located wholly in the upper part of the reaction chamber, and has an inlet mouth that is substantially either perpendicular or parallel to the upper surface of the acceleration duct. The centrifugal separator (2) has substantially straight vertical walls. The assembly comprising the reaction chamber (1), the centrifugal separator (2), and the rear cage (3) of the comprises a basic module.
