ABSTRACT:
The invention relates to recuperators used mainly with industrial furnaces, which is provided with a radiation heat exchanger and a convective heat exchanger arranged one behind the other. These known types of recuperators are usable to exploit the waste heat of flue gases only with very low efficiency and have a voluminous and complicated structure.
The improvement of my invention is in that the convective heat exchanger has a central heat exchange part and at least one conduit for blowing air on the bottom surface of the central heat exchanger part.
The recuperator according to this invention has a longer endurance, a much higher effectiveness and a more simpler, smaller construction.
