ABSTRACT:
A recuperator-type heat recovery apparatus may have a configuration for passing hot waste gases through an elongate, extended cyclone-type circulation path within a constricted area effecting the flow of the gases against a heat transfer surface and providing an extended retention time for radiating and conducting heat into this heat transfer surface and concurrently for changing the velocity of the gases resulting in a separation or fallout of heavier particles of dust and other matter entrained in the gases; a controlled introduction of abrasive particles operates to clean away buildup of contamination and dust deposits from all surfaces within the apparatus, the spent abrasive particles and dirt separating from the gases and being recovered.
