A centrifugal separator for separating particles from gases is a vortex chamber composed of cooling planar plates or panels (i.e. they are distinctly non-cylindrical), having at least one gas inlet, at least one gas outlet and at least one outlet for the separated particles. The cross section of the side walls of the vortex chamber forms a distinctly non-circular gas space (e.g. a polygonal cross section), have a circularity of greater than 1, e.g. >=1.1, and preferably >=1.15. One or more vertical, parallel gas vortices may be created in the vortex chamber, the gas introduced into vertical narrow slots. The outlets for separated particles are not on the same symmetrical axes as the outlets for purified gas. Two adjacent vortices may be provided in a common rectangular chamber. The separator is preferably in conjunction with a circulating fluidized bed reactor.
