Cyclone separator having water-steam cooled walls |
(57) A cyclone separator has an outer cylinder is formed by a plurality of vertically-extending,
spaced, parallel tubes and extends around an inner pipe in a coaxial relationship
therewith to define an annular chamber. A portion of the tubes forming the outer cylinder
are bent out of the plane of the cylinder to form an inlet opening in a tangential
relationship to the annular chamber for receiving gases containing solid particles
and directing same through the annular chamber for separating the solid particles
from the gas by centrifugal forces. The tubes are bent radially inwardly towards the
inner pipe to support the inner cylinder steam and/or water is passed through the
tubes to cool the outer cylinder.
