摘要：
A furnace system includes a burner assembly that includes a burner configured to produce a flame and a heat exchanger that includes a plurality of tube passes. The plurality of tube passes cooperatively forms a conduit for flowing combustion products generated by the burner assembly. Each tube pass of the plurality of tube passes overlaps with other tube passes of the plurality of tube passes. A first tube pass of the plurality of tube passes is configured to receive the flame, and the first tube pass includes a first plurality of surface enhancements extending radially outward from an outer surface of the first tube pass relative to a central axis of the first tube pass. The furnace system also includes a baffle that is coupled to the burner assembly, extends toward the first tube pass, and is configured to contact the flame and the first tube pass.
