Abstract
A heat exchanger, for use in particular in connection with the process outlets at paper, pulp and board mills, including substantially parallel tubes or equivalent arranged in a duct. An air flow that delivers heat passes through the tubes and an air flow that receives heat passes through gaps between the tubes in accordance with the cross-flow principle. The heat faces of the tubes are made larger at the side of the flow that receives heat by means of ribs, lamellae or equivalent, and an air that is moist, saturated, or near its saturation curve is used as the air flow that delivers heat in the heat exchanger.
