Abstract

L'invention concerne un procédé et un dispositif permettant de produire facilement une grande quantité de vapeur surchauffée à haute température à partir d'une quantité d'eau. On utilise un dispositif de production de vapeur surchauffée comprenant un manchon (1) fait d'un matériau résistant à la chaleur avec un orifice d'introduction de jet d'eau à une extrémité (1a) et une sortie (3) d'éjection de la vapeur surchauffée à l'autre extrémité (1b), une bobine (5) d'excitation enroulée autour de la partie périphérique extérieure du manchon (1), et des éléments chauffants (4) perméables à l'air faits d'un matériau électroconducteur chargés dans le manchon (1). De l'eau est injectée dans le manchon d'une extrémité (1a) du manchon (1) chargé avec les éléments chauffants (4) imperméables à l'air faits d'un matériau électroconducteur, puis les éléments chauffants (4) imperméables à l'air chargés dans le manchon (1) sont chauffés par induction à haute fréquence, la vapeur surchauffée à haute température étant ainsi éjectée en grandes quantités par la sortie (3) d'éjection dans l'autre extrémité (1b) du manchon (1).
