<P>PROBLEM TO BE SOLVED: To provide a steam superheater which easily produces superheated steam made by heating steam up to above 100°C under normal temperature condition at low cost. <P>SOLUTION: This steam superheater is provided with a feed water tank 1 for reserving water, an evaporating dish 7 to which water is fed from the feed tank 1, a capillary heat-proof cloth 5 absorbing water reserved in the evaporating dish and having a dome-shape corresponding to a heating portion for heating, and a gas burner 6 for heating the capillary heat-proof cloth 5. The absorbed water is generated as vapor by heating the capillary heat-proof cloth 5 by the gas burner 6 and heated air is mixed with the vapor, and accordingly superheated steam is generated. The capillary heat-proof cloth 5 has a shape made by closely webbing non-combustible fiber in a dome-shape and absorbs water reserved in the evaporating dish, and upward air flow of the generated superheated steam is discharged by a spirally rotating guide plate as a rotating air flow. <P>COPYRIGHT: (C)2004,JPO |
