ABSTRACT:
A radiant tube heater is provided for a gas fired burner which fires heated products of combustion into an inner longitudinally-extending tube which is concentrically pinned to an outer longitudinally-extending tube which in turn is concentrically mounted within a heat transfer, tube which radiates heat to work. The outer and inner transfer tubes have closed axial ends opposite the burner and the inner tube is radially spaced closely adjacent the outer tube to define an annular heat transfer passage therebetween. A specific hole size pattern in the inner and outer tubes in combination with the radial distance of the heat transfer passage insure long path gas flow lengths which promote laminar flow and even heat distribution along the length thereof thus producing a radiant tube which radiates heat uniformly from the heat transfer tube to the work along its length.
