Abstract:
1. A superheated vapor generator comprising: a tubular container extending substantially vertically and having closed top and bottom ends; a high frequency induction heating coil wound around the tubular container; a heating medium placed in the tubular container; the heating medium being formed of material that can be heated by electromagnetic induction; the heating medium having a number of vapor passages extending therethrough substantially longitudinally of the tubular container; the tubular container having a heating section formed therein where the heating coil heats the heating medium; the tubular container further having a non-heating section formed therein under the heating section; a supply passage through which material for superheated vapor can be supplied from a position above the heating medium to the non-heating section; a passage structure provided in the non-heating section so that the material supplied through the supply passage can flow through the structure into the vapor passages of the heating medium; a discharge passage formed above the heating medium so that superheated vapor can be discharged through the discharge passage; a closing member fitted removably to the tubular container to close the top end of the container; a supply pipe defining the supply passage thereinside and fixed to the closing member; and a discharge pipe defining the discharge passage therein and fixed to the closing member.
