[Also in Groups XII and XIII] In a water-tube steam generator operating at a high pressure, for example 1500 1b. per square inch or over, the steam-water mixture from generating tubes 22 discharges into a steam and water drum 20 and passes downwardly through annular spaces provided between internal partitions 70 and the drum to the lower ends of a double row of steam separating and purifying units U wherein the steam is separated from the mixture, washed with clean feed water and dried. Each unit comprises a separator portion S consisting of a vertical tube 73 housing a spinner 76 and mounted within a tubular jacket 78 to the upper end of which is attached a plate 82 having a central opening defined by a downwardly directed collar 84. The spinner causes the steam-water mixture to rotate at high speed in tube 73, most of the water separating by centrifugal force and passing under the collar 84 to return to the main body of water in. the drum via the jacket 78. Mounted above plate 82 is a bubble washer W consisting of a number of parallel U-shaped trays 90, the adjacent upstanding sides of which are covered by inverted U-shaped bubbling hoods 92. A pipe 56 conveys clean feed water from the feed supply pipe 50 to the trays 90 so that, in operation, the trays are filled to a level determined by weir plates 100 at their outer ends and steam bubbles through the water whereby most of the silica and other deleterious vapours which may be present in the steam are removed. Above washer W is mounted a drier D consisting of two stacks of closely-spaced corrugated plates 108. Most of the water entrained in the cleaned steam is removed in its passage between the plates, the remainder being extracted in final drying screens 60 through which the steam passes to the outlet pipe 40. The rectangular casing of washer W may be replaced by a cylindrical casing, the troughs 90 then being arranged in a radial or concentric manner (Figs. 9 to 14, not shown).
