ABSTRACT:
A heat exchanger device for recovering waste heat from a contaminated hot gas that carries solid and precipitable contaminants capable of being liquified by heat. The device has a heat exchanger with a plurality of spaced heat conducting passages for the contaminated hot gas and a plurality of spaced second passages for a cooler second gas with these first and second passages being alternately interleaved for efficient heat transfer and a heat conducting fin in each of the cool gas, such as air, passages for aid in transferring heat between the gases. The disclosure also includes means for selectively applying heat to the outer sides of the heat exchanger for transfer of liquifying heat to the deposited solid contaminants.
