Abstract

PURPOSE: To lessen the degradation in heat loss and the refractory thermal insulation of an inner side by disposing an annular chamber between concentric inner and outer cylinders and constructing the outer cylinder by bending the prescribed portions of plural pieces of tubes extended perpendicularly respectively in parallel and opening these tubes. CONSTITUTION: A separator 10 is part of a boiler system including a fluidized bed reactor, etc., and the inlet formed by the bent tubes 24a, 28a admits high- tap. gases. The gases contg. fine solid fuel particles swirl in the annular chamber between the cylinder 32 and an inner pipe 61 and the solid particles are splashed and gathered to the inside wall of the cylinder 32 by centrifugal forces. These particles are dropped by gravity into a hopper 16. The gases in the annular chamber are prevented from ascending by a roof 52 and are admitted into the inner pipe 61 before the gases emerge from the outlet formed by the side walls connected to headers 48, 50. The gases pass the pipe. At this time, water, etc., are passed through tube groups 24, 26, 28, 30 from an external water tank, by which the cylinder 32 may be cooled.
