Abstract: This invention relates to a regenerating, hazardous waste gas fume and odor incinerator. The incinerator comprises a combustion chamber (12) and at least three heat exchanger regenerator beds (26, 28, 30) through which the waste gases pass selectively for preheating on their way to the combustion chamber and the processed, heated gases are passed through for cooling before exhausted. All three regenerator beds are cycled from a cooling position in which they absorb heat from the previously processed gases to a second position where they preheat waste gases en route to the combustion chamber to an inactive position where they do not receive gases either from the waste supply or from the combustion chamber. The waste gases, after being preheated, are directed to the combustion chamber through a plenum chamber (14) in which is located a combustion burner (16). The preheated waste gases are directed through the flame of the burner into the combustion chamber for ignition and for combustion therein.

Abstract: Heat recovery and replacement air preheating apparatus for use in industrial heat treating processes is disclosed as including at least a pair of thermal recovery and storage units, B, C wherein each storage unit contains a plurality of heat exchange elements 32, 33 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 D, 62 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 exhaust heat is stored and transferred to the replacement air flow.

Abstract: 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.
