Goosman, R

A waste heat recovery device particularly usable for heating the air traveling through a cold air return duct to a hot air gas heating furnace is disclosed which includes an exhaust box securable to the wall of the furnace and adapted to receive exhaust gases therein to gather heat in the plenum chamber defined by the exhaust box. The exhaust box also includes an exhaust gas outlet to expel gases to the existing heater stack or flue for venting, the plenum chamber including an exhaust coil being in fluid flow communication through a conduit to a return coil which is located within the cold air return. The conduit means is partially filled with a thermal transfer fluid such as water which will boil within the conduit in the exhaust coil means and will condense within the conduit in the return coil means and as such will effect rapid thermal transfer from the heated exhaust waste to the incoming cold air traveling through the cold air return and thereby achieve waste heat recovery.
