Abstract: A circulating fluidized bed reactor includes a filter apparatus for separation and recycling of fine particles which are entrained by the flue gas. The housing of the filter apparatus has a plurality of vertically disposed ceramic filtration tubes. The reactor chamber and filter housing are arranged back-to-back and have a common wall therebetween. A pre-separator for separation of coarse particles is provided which connects the reactor chamber with the filter apparatus. The reactor, the separator and the filter apparatus are encased in a pressure-proof cylindrical vessel. The walls of the reactor chamber and the filter housing can be water-cooled. In another form, the filter is comprised of a plurality of porous plates having ribs abutting adjacent plates to define passageways through the filter.
