A deep fat fryer includes three horizontally aligned heat tubes surrounded by cooking oil in a cooking vessel. An infrared type combustion burner is in each of the two outer tubes and combustion products therefrom are directed along separate paths back and forth through the center tube. The center tube includes a divider, having a zig-zag metal baffle mounted on each side, that forms an upper and lower passage in the tube. A blower forces air to the burners and combustion products from the outer tubes flow over the baffles in the passages of the center tube and out a flue via a divided, insulated plenum.

In combination in a commercial cooking vessel: a pot for holding a cooking medium; three horizontally aligned separate heat tubes in said pot, each substantially fully surrounded by said cooking medium; an infrared combustion burner in each of the outer ones of said three heat tubes; flue means coupled to the middle one of said three heat tubes for venting combustion products from said combustion burners; said middle one of said heat tubes receiving the combustion products from each of said outer ones of said heat tubes and passing said combustion products to said flue means; and means in said middle one of said heat tubes for enhancing heat transfer from said combustion products to said cooking medium, said enhancing means comprising a divider in said middle one of said heat tubes, and baffles on each side of said divider for disrupting the laminar flow and lengthening the path of travel of said combustion products.
