SUPERHEATED STEAM-GENERATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a superheated steam-generating device capable of regulating the temperature of the generating superheated steam in good response thereto sharply over a wide range.SOLUTION: A superheated steam-generating device comprises: a heating container made of an electrically conductive metal for storing water inside; a first induction heating coil provided along an outer circumference of the heating container for generating steam by induction-heating the heating container to heat the inside water; a magnetic absorber provided along the circumference of the induction heating coil; a heating tube provided along an outer circumference of the magnetic absorber and made by winding an electrically conductive metal tube helically, through which the steam generated from the heating container is communicated inside; and a second induction heating coil provided along an outer circumference of the heating tube for generating superheated steam by induction-heating the heating tube to heat the inside steam.
