Patent attributes
A superheated vapor generator has a tubular, vertically extending container with closed ends. A high frequency induction heating coil is wound around the container. A heating medium is placed in the container and is made from material heatable by electromagnetic conduction. A number of vapor passages extend through the heating medium longitudinally of the tubular container. The tubular container has a heating section with the heating coil and a non-heating section under the heating section. Material for superheated vapor is supplied through a supply passage from a position above the heating medium to the non-heating section. A passage structure is provided in the non-heating section for flow of material supplied through the supply passage therethrough into the vapor passages of the heating medium. A discharge passage is formed above the heating medium. A discharge passage is formed above the heating medium for discharging superheated vapor.
