Apparatus for generating superheated vapor using waste heat recovery

An apparatus for generating superheated vapor using waste heat recovery comprising:

• a housing comprising an inlet tank and an outlet tank at both ends, wherein exhaust gas is introduced through the inlet tank and discharged through the outlet tank;
• a plurality of exhaust gas tubes disposed inside the housing so as to be spaced apart from each other at predetermined distances in a top-bottom direction;
• and
• a plurality of working fluid tubes alternating with the plurality of wave fin structures,
• wherein an inlet pipe and an outlet pipe are disposed on a side surface of the housing, wherein working fluid is introduced through the inlet pipe and discharged through the outlet pipe, the inlet pipe and the outlet pipe are connected to the plurality of working fluid tubes so as to communicate each of the plurality of working fluid tubes, and an upper surface and a lower surface of each of the plurality of working fluid tubes directly adjoin to adjacent exhaust gas tubes of the plurality of exhaust gas tubes.
