    Patent number: 5235667
    Abstract: A heater for radiant heating of an object in a heating tunnel, furnace or the like has a layer of ceramic fibers through which a fuel/air mixture is fed for combustion at the surface and use of the heater as a gas burner. Partly embedded in the surface is an electrical-resistance heater which is heated up by the burner action and then can be energized to provide controlled heating of the object when the gas is shut off. A flow of cooling air through the heater can terminate the heating operation and rapidly quench the heater.
