A gas-flow heat exchanger comprising a set of parallel, spaced, heat-conductive areas providing between them a stack of pockets each containing parallel baffles which define a platen of passageways guiding the gas-flow path through the pocket between inlet and outlet openings. The openings being arranged in four parallel lines at the sides of the stack, two of the lines respectively containing the inlet and outlet openings associated with the gas flow paths of alternative pockets. The remaining two lines respectively containing the inlet and outlet openings associated with the remaining pockets. Each pocket containing a removable frame formed with the openings provided at the ends of the gas flow path through it and supporting within the frame the parallel baffles which divide the gas-flow path into the platen of passageways. All of the passageways provide a substantially equal dwell time to gas passing therethrough.
