Abstract
A heat exchanger for reclaiming energy from an exhaust airstream. The exchanger includes a porous metal element suitable for absorbing heat from the exhaust airstream, means for reciprocally moving the porous element back and forth transversely to the exhaust airstream, an inlet duct for receiving the exhaust airstream and directing it through the porous element to an outlet duct, and reclaiming air blower means for delivering two heat-reclaiming airstreams through the porous metal element, one on either side of the exhaust airstream, and an air exhaust fan in the path of said exhaust airstream for drawing said airstream through said porous element.
Claims37
A heat exchanger for reclaiming energy from an exhaust airstream, said exchanger comprising
- a porous element suitable for absorbing heat from said exhaust airstream,
- means for reciprocally moving said porous element back and forth traversely to said exhaust airstream,
- an inlet duct for receiving said exhaust airstream and directing it through said porous element to an outlet duct,
- reclaiming air blower means for delivering two heat-reclaiming airstreams through said porous element, one on either side of said exhaust airstream, and
- an air exhaust fan in the path of said exhaust airstream for drawing said airstream through said porous element,
- said blower means and said exhaust fan being sized so that the total volumetric rate of flow in said reclaiming airstreams is equal to or greater than in said exhaust airstream.
