ABSTRACT:
The heat exchange structure comprises a series of tubes arranged in a circular pattern extending between upper and lower manifolds. Water flows from the upper manifold through these tubes to the lower manifold. Annular fins are stacked on these tubes. A larger tube is arranged concentric with each of the smaller diameter water-carrying tubes and hot gaseous products of combustion flow through these larger tubes in counterflow to the water flow through the water tubes. The fins have through-holes allowing the hot gases to pass through the stacks of fins. The combustion chamber is located centrally just above the lower manifold. Ambient air is introduced via perforations in the side wall of the casing near the upper manifold and flows downwardly past the heat exchange structure for recuperative effect before reaching the combustion chamber.
