The lower ends of spaces 22 are closed by solid parts of a frusto-conical wall 6, which drains water separated by vanes 12 and plates 13 into annular sump 24 for removal. via outlet 25. Sumps 16 under banks of plates 13 also drain into sump 24 via ducts 17. The radially outer sides of outlet spaces 23 are defined by triangular plates 19 adjacent the housing wall. Sheets 20 are four-sided and twisted so that each space 23 comes to a radial edge at the top but is triangular in horizontal section at the base. The separator is used in steam turbine plant to dry the steam, either as a separate unit or as a component part of a separator-reheater connected between high and low-pressure cylinders of the turbine.
