ABSTRACT:
The present invention relates to a device for generating superheated steam, comprising: 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 housing10therethrough; 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).
