This patent describes a fuel fired radiant tube burner. It comprises a first generally cylindrical heat tube; a second cylindrical heat transfer tube concentrically disposed within the heat tube and defining a longitudinally-extending annular exhaust gas passageway therebetween; a third cylindrical burner tube concentrically disposed within the second tube and defining a longitudinally-extending annular heat distribution passageway therebetween; burner means within the third tube at one axial end of the third tube and sealed with respect thereto for igniting, combusting and burning a source of fuel and air to form heated products of combustion within the third tube casing; plate means closing the first, second and third tube axial end openings which are adjacent one another, the plate means effective to cause the products of combustion to enter the heat distribution passageway; and aperture and opening means associated with the heat distribution passageway for developing a substantially laminar flow of the products of combustion within the heat distribution passageway.
