Abstract

The electrothermal generator includes a tube (1) in its assembly, made from a glass-fibre reinforced cross-linked resin and composed of an inner thin skin (4) and an outer collar (5) which will confer upon the tube suitable resistance to pressure. The three heating-element segments (11, 12, 13) formed from graphite-based strips wound in spiral turns tightened over the skin (4) and provided, at each of their ends, with connection cables (11c, 11d; 12c, 12d; 13c, 13d) are wound over the skin (4) and under the collar (5). The winding segments occupying a length of about 1 metre of an 82/90 mm cube, and the skin (4) being about 1 mm thick, the generator possesses a nominal power of about 50 kW and the temperature drop between windings and heated liquid will be of the order of 40 DEG C. <IMAGE>
