[Class 64(i)] [Also in Groups XXVI and XXVIII] In a gas turbine plant, the exhaust gases on their way to the main air heater pass through a combined cleaner and regenative air-heater of the kind described in Specifications 618,632 and 622,375. The gas cleaner and heater comprises three zones 10, 14, 11, Fig. 2, through which falls a stream of small heat-carrying bodies or pebbles. In the zones 10, 11, the stream is enclosed by walls of inclined slats 17, 18 and in the zone 14 the stream cascades over inclined plates 21. The pebbles are returned from the bottom of the stream to the top by a bucket conveyer 20. The exhaust gases from the turbine are led through the zone 10 passing between the slats 17 and traversing the stream of pebbles. In this, the pebbles are heated and solid or tarry matter in the gases adheres to the pebbles. The cleaned gases then pass to the main pre-heater. In the zone 14, the cascading pebbles are subjected to an air stream produced by a fan 22 and the adhering matter is removed and conveyed to a cyclone separator 24. A part of the air from the plant compressor is led through the zone 11 and traverses the stream of pebbles which give up their heat to the air.
