Apparatus for generating superheated vapor using waste heat recovery

Abstract

An apparatus for generating superheated vapor using waste heat recovery. The apparatus includes a housing having inlet and outlet tanks at both ends through which exhaust gas is introduced and discharged. A plurality of exhaust gas tubes are disposed inside the housing so as to be spaced apart from each other at predetermined distances in a top-bottom direction. A plurality of working fluid tubes alternate with the plurality of wave fin structures. Inlet and outlet pipes through which working fluid is introduced and discharged are disposed on a side surface of the housing. 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. An upper surface and a lower surface of each of the plurality of working fluid tubes directly adjoin to the adjacent exhaust gas tubes.

1 . 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.   
     
     
         2 . The apparatus according to  claim 1 , wherein air communication holes are formed so as to penetrate through an outer surface of at one side of the housing, each of the plurality of exhaust gas tubes has a flat panel structure, and each of the plurality of working fluid tubes has a flat surface formed on either an upper surface or a lower surface, the flat surfaces of the plurality of working fluid tubes directly adjoining to the plurality of exhaust gas tubes. 
     
     
         3 . The apparatus according to  claim 1 , wherein each of the plurality of working fluid tubes has an oval cross-sectional structure that has a flat surface on either the upper surface or the lower surface. 
     
     
         4 . The apparatus according to  claim 1 , wherein each of the plurality of working fluid tubes is bent into a shape of an S, one end of each of the plurality of working fluid tubes is connected to the inlet pipe, and the other end of each of the plurality of working fluid tubes is connected to the outlet pipe. 
     
     
         5 . The apparatus according to  claim 1 , wherein each of the plurality of exhaust gas tubes has wave fins therein, first and second fitting assemblies are provided on both ends of the plurality of exhaust gas tubes, each of the first and second fitting assemblies comprising a plurality of fitting slots, and both ends of the plurality of exhaust gas tubes being fitted into the fitting slots of the first and second fitting assemblies.
