Abstract (en)
[origin: DE19604565A1] The invention concerns a device for separating solids particles from a gas flow of a circulating fluid bed reactor (1), the solids particles being conveyed in this gas flow. Means are provided which influence the gas flow such that centrifugal and gravitational forces which are greater than the gas flow entrainment forces act on the solids particles, so enabling particles of a given minimum size to be separated from the gas flow. According to the invention, the structure of the circulating fluid bed plant is rendered particularly compact in that the gas flow leaving the circulating fluid bed reactor (1) passes to a flow duct (4) which guides said flow about a horizontal cyclone axis (16) on a circular arc (17) in the downward direction. From here, the gas flow is delivered to a transfer duct (7) suitable for conveying it further. In the vertical direction the flow duct (4) merges into a separation chamber (15) which widens in corresponding manner at the bottom and in which the separated solids particles drop to the bottom.
