Abstract: The present disclosure provides for an apparatus for recovering exhaust energy. The apparatus is generally provided with a waste energy stream inlet for directing an incoming waste heat energy stream from a waste energy stream generator, a heat exchanger in fluid communication with the waste energy stream inlet, a waste energy stream outlet distal from the waste energy stream inlet, a recycled energy stream outlet operatively connected and in fluid communication with said air flow that receives heat, and collecting means.

Abstract: The present disclosure provides for a heat exchanger. The heat exchanger generally comprises a duct and substantially parallel tubes having an outer wall and arranged in the duct to define gaps therebetween. An air flow is directed through the duct to deliver heat through the gaps and over the outer walls of the tubes. A second means directs an air flow that receives heat through the tubes. The air flow that delivers heat generally comprises air that is moist, saturated, or near its saturation curve. The heat exchanger also comprises collecting means arranged in the duct for collecting the condensate flowing along the outer walls of the tubes upon exiting from the duct at the outlet.
