Abstract
A circulating fluid bed reactor comprises a reactor chamber having a circumscribing wall, a particle separator to receive a particle - gas suspension from the reactor chamber, and means for returning the particles separated by the particle separator to the reactor chamber. In order to eliminate problems due to heat expansion of the parts of the reactor and to provide a simple structure, the particle separator has at least one cyclone having a chamber with a cylindrical outer surface forming a part of the circumscribing wall of the reactor chamber.
