Abstract
In a multi-poise furnace having multiple parallel heat transfer stages, each stage having superimposed flow passages lying in a common plane. The last passage in each stage containing laterally-disposed indentations in opposed side walls for increasing the heat transfer surface area, and the walls of the last passage being further configured to conduct any condensate formed in the heat exchanger out of the exit region of the exchanger, regardless of the furnace orientation.
