ABSTRACT:
A recuperator structure for recovering heat values from a moisture laden hot gas stream that uses a plurality of heat exchangers having separated sets of passages through each in heat exchange relationship with each other, means for directing the hot gas stream through a first set of passages and means for directing ambient air through a second set of the passages and to a space for transferring heat to the space, means for precooling the hot gas stream upstream of the heat exchangers to condense moisture from the hot gas stream, means including separate ducts for arranging the heat exchanger and corresponding precooling means in first and second separate banks, flow control means in each duct for directing the hot gas stream selectively through the separate ducts while maintaining the other duct dormant and means for directing a heating medium through the precool means in the dormant duct to melt any frost remaining on the dormant duct precool means.
