ABSTRACT:
A cyclone separator roof which accommodates differential thermal expansion and contraction. When the inner and outer cylinders of a cyclone separator are operated at different temperatures, such as in a cyclone separator having walls formed by water-steam cooled tubes, this causes differential thermal expansion and contraction circumferentially and radially across a roof extending between such inner and outer cylinders. The cyclone separator roof of the present invention includes a corrugated, annular upper seal plate having expansion joints which enable the roof to accommodate differential circumferential and radial thermal expansion and contraction. The corrugations in the plate extend radially from the center of the plate and accommodate differential circumferential thermal expansion and contraction across the roof. The expansion joints are disposed in the plate and are aligned coaxially with the inner and outer circumferences of the plate to accommodate differential radial thermal expansion and contraction across the roof.
