An oxyhydrogen blowpipe 4 diffuses heat from its very hot flame, at the centre of a heat exchanger 3 made of thin sheet metal placed inside the thick wall 1 of a boiler. Water 5 is pumped between the two walls of the boiler 1 and of the overheated exchanger 3. It vaporises and, from the apex of the boiler 6 where it collects, the steam is channelled inside the exchanger 3 via a tube 7 which emerges on the hydrogen plus oxygen combustion flame. The mixture of steams 8 creates a temperature balance which must be sufficiently high to bring the water pulsed between the boiler and the exchanger 3 to the boiling point. The pressure rises in the enclosure of the boiler and this very hot steam under pressure can, from the enclosure of the exchanger 3, be supplied to any heat machine 9. <IMAGE>
