[Class 110 (iii).] Compressed gases produced in an explosion chamber, preferably that of a gas turbine, are given a whirling motion and passed through a heat-exchanger such as a boiler. Fig. 1 shows the lay-out, the explosion chamber A being provided with the usual automatically operated valves, viz., B for air supply, C for fuel supply, and D for discharge. The products of combustion pass through a channel R into a heatexchanger S, Fig. 2, which is made up of a number of oval chambers 7 connected alternatively at their peripheries and centres by pipes 8 and passages 11. Ribs and projections are arranged to ensure a whirling motion. Water is passed by pipe W2, the cooling jackets of the explosion chamber A and the channel R, and a throttle valve V2 to the space surrounding the chambers 7. Water is led also to spaces 17, 18 at the ends of the heat-exchanger past throttle-valves V1, V3, and all of the superheated water is passed through a reducing valve Z to a vessel W from which steam is drawn off at Y. The unvaporized water is returned to the circuit by a pump Z1, and make-up water is supplied by a pump Z2. The passages are arranged so that the gases increase in velocity as they pass through the heatexchanger. In a modification the water is passed through tubes surrounded by baffle tubes traversed by the gases. 419,117.
