Abstract

Chaudière électrique de production de vapeur compor­ tant des éléments chauffants plongés dans le liquide, lesdits éléments chauffants étant constitués par des tubes (1) ou des plaques, non isolés, électriquement conducteurs, alimentés électriquement à chacune de leurs extrémités (6, 7), les surfaces desdits éléments conducteurs étant en contact direct avec le liquide caractérisé en ce que lesdits éléments chauffants comportent des aspérités (2, 3) de manière à ce que ces surfaces ne soient pas isothermes. Compor steam generator both heating elements immersed in the liquid, said heating elements consisting of tubes (1) or plates, not insulated, electrically conductive, powered electrically at each of their ends (6, 7), the surfaces of said conductive elements being in contact direct with the liquid characterized in that said elements heating elements have asperities (2, 3) so that that these surfaces are not isothermal.
