ABSTRACT:
A controlled atmosphere furnace having radiant heating tubes, through which hot gases from a fuel burner are passed, is converted to electrical operation by removing the fuel burner and exhaust connections from the heating tubes and replacing these with electrical connector extensions connected to an electrical power source so that electrical current is driven longitudinally through the heating tube walls and converted therein to heat which is radiated into the furnace enclosure.
