Claim:
A device for generating superheated steam which comprises: a housing 10 having a cylindrical body and a combustion chamber with a hollow space portion formed in the cylindrical body, the housing having a discharge outlet 13 formed at a bottom end thereof so as to allow superheated steam to be discharged to the outside therethrough; a cover 14 mounted on a top end of the housing and having an injection inlet 12 formed at a top end thereof so as to allow steam to be injected into the housing 10 therethrough; a plurality of interval-maintaining means 20 horizontally stackingly arranged on top of one another in the combustion chamber of the housing in such a fashion that interval-maintaining means of even and odd number rows are alternately disposed and equidistantly spaced apart from one another, the interval-maintaining means of even and odd number rows having different outer diameters so as to define a fluid-communicating passageway 25 between the inner wall of the combustion chamber 11 and the interval-maintaining means 20 ; and a plurality of heating means 30 penetratingly mounted vertically in the plurality of interval-maintaining means 20 in such a fashion as to be arranged spaced apart from one another equidistantly at a peripheral portion of the interval-maintaining means so as to heat fluid passing through the fluid-communicating passageway 25 .
