Abstract
A heat recovery system is disclosed for a pulse combustion drying system in which the exhaust gas of combustion from a pulse combustor passes successively through a dryer, a product collector and a scrubber. The heat of the exhaust gas is recovered in the scrubber by spraying with water or other liquid and transferring by heat exchange the heat absorbed by the water to compressed air, and passing the heated compressed air successively through a membrane heat exchange tube on the wall of the product collector and a membrane heat exchange tube on the wall of the dryer. The air is discharged finally in an air-injection nozzle of the pulse combustor.
