An infrared radiant heating apparatus is described for use in heating articles rapidly and efficiently by infrared radiation absorption. The apparatus comprises a support frame, a heat absorbing and radiating heater mounted on the support frame, the heater including an inner heat cone and an outer heat cone spaced apart from each other and joined together along their outer peripheries to define a combustion chamber. The outer heat cone has an exposed convex conical surface and forms a heat absorbing and radiating material. The heater further includes a fuel pipe extending to a nozzle which extends through the inner heat cone and opens into the combustion chamber, a shroud surrounding the fuel pipe, a cylindrical jacket surrounding and spaced apart from the shroud and joined at one end to the inner heat cone, a helical exhaust pipe disposed within the jacket and surrounding the shroud, the inner cone having exhaust ports along its outer periphery, with each of the exhaust ports connected to the helical exhaust pipe by a tubular pipe. Means for channeling combustion and exhaust gases from the combustion chamber lies along the inner surface of the outer cone and to the exhaust ports. Burner means including means for supplying fuel to the fuel pipe and means supply air through the space between the jacket and the shroud and to the nozzle. Hot gases pass through the tubular pipes and through the helical exhaust pipe and the incoming combustion air passes over the helical exhaust pipe and is preheated from the transfer of heat.
