Hebrank, W H

Heat recovery and replacement air preheating apparatus for use in textile heat treatment machinery is disclosed as including a pair of thermal recovery and storage units wherein each storage unit contains a plurality of thermal mass disks which operate as heat sponges to pick up heat from exhausts as it leaves the dryer and subsequently to put that heat into entering replacement air whereby the cost in elevating the replacement air is greatly reduced. A control valve connected between the two thermal storage units cycles the reverse exhaust and replacement air flows alternately through the thermal storage units in a manner that a substantial amount of the exhaust heat does not reach the ambient environment and the alternating replacement air flow maintains the thermal heat recovery and storage units and associated apparatus cool and clean of lint and the like residuals.
