ABSTRACT:
The present invention provides a new and improved apparatus and method of carburizing ferrous metal parts. In one embodiment of the invention the apparatus comprises a radiant heater tube within which a source of hydrocarbon fuel is fully combusted, and a generator tube surrounding and forming a cavity around at least a portion of the radiant heater tube. The generator tube includes an input for air and enriching gas and an output to the process chamber of the furnace. The enriching gas is partially combusted or decomposed in the generator tube. This partially combusted gas is utilized to produce a carburizing gas for use in the process chamber of the furnace.
