Apparatus for reheating the exhaust steam or other working fluid from an external combustion engine, e.g., a turbine, comprises two contra-rotating drums, each containing conduit means arranged in a spiral through which the exhaust fluid flows in succession, the drums being located in a cylindrical housing which is divided into four quadrants through which the drums rotate, two of the quadrants being supplied with heat from an external source, one quadrant being neutral and one quadrant being cooled. |
