A wet base boiler of the multi-sectioned type, that is, a boiler in which the fire box is surrounded by water. Each heat exchanger section of the boiler being arranged and constructed to provide an improved heat transfer surface when contacted by the heated gases emanating from the fire box. The heat transfer surface of each section comprises opposing parallel walls having a plurality of equispaced ribs disposed thereon to define a curvilinear path between adjacent ribs, the ribs formed on one wall of a heat exchanger section being antisymmetrical with the ribs formed on the opposing wall of the heat exchanger section, each rib of each wall having spaced fins or cusps and each fin or cusp having a height so as to be spaced from the fins branching from the ribs of an adjacent heat exchanger section.
