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.

Description

TECHNICAL FIELD[0001]The present invention relates to an apparatus for generating superheated vapor using waste heat recovery, and more particularly, to an apparatus for generating superheated vapor using waste heat recovery which can significantly improve the efficiency of generating superheated vapor from working fluid using waste heat such as of exhaust gas.BACKGROUND ART [0002]It is well known that the heat efficiency of internal combustion engines used in vehicles, vessels, or the like is very low. Although only about 30% of fuel supplied to internal combustion engines is used as output energy, it is difficult to improve fuel efficiency.[0003]Energy that is not extracted as usable mechanical energy is discharged to the air as waste heat, for example, through the discharge of exhaust gas from an internal combustion engine, charge air cooling, or heat dissipation from engine coolant.[0004]Waste heat recovery systems which promote an improvement in fuel efficiency by actively reco...

AI Technical Summary

Benefits of technology

The present invention aims to reduce the likelihood of high-temperature and high-pressure working fluid leaks by minimizing the thermal stress of the fluid tubes through which it passes. It also seeks to improve the heat exchange efficiency of the working fluid by increasing the area where it comes into contact with exhaust gas.

Problems solved by technology

It is well known that the heat efficiency of internal combustion engines used in vehicles, vessels, or the like is very low.

Although only about 30% of fuel supplied to internal combustion engines is used as output energy, it is difficult to improve fuel efficiency.

Since the apparatus for generating superheated vapor of the waste heat recovery system is configured such that the high-temperature and high-pressure working fluid exchanges heat with the high-temperature exhaust gas, it is highly possible that the working fluid may leak and the leaking working fluid may cause severe problems inside a vehicle, which are problematic.
