Abstract:
1. A method of exchanging heat comprising the steps of: providing an indirect heat exchange section, the indirect heat exchange section conducting a fluid stream within a plurality of pathways, the indirect heat exchange section comprising a top, a bottom, an air inlet and an air outlet, moving air between the air inlet and the air outlet of the indirect heat exchange section, the air moving through the indirect heat exchange section exchanging heat with the fluid stream within the plurality of pathways in the indirect section, wherein the indirect heat exchange section is comprised of a plate type heat exchanger, the plate type heat exchanger comprised of a series of adjacent plate cassettes forming an alternating arrangement of a first series of flow passages and a second series of flow passages, an inlet header and an outlet header operatively connected to the first series of flow passages such that the fluid stream can pass into the first series of flow passages and out from the first series of flow passages, the second series of flow passages arranged such that the air moving through the indirect section passes through the second series of flow passages, wherein the air moving through the indirect heat exchange section moves counter-current to the direction of flow of the fluid stream through the indirect heat exchange section.
