ABSTRACT:
A flame-out-resistant portable torch for igniting gas-air blasts in industrial gas furnaces includes an inner pipe for receiving gas at one end, with the opposite end closed and a gas-expulsion slot along one side, surrounded in coaxial spacing by an outer pipe with an air-induction side slot 180.degree. from the slot in the inner pipe, the outer pipe has air-induction butt end opening, vents around portions of it near the slots, and a flame expulsion end with anti-back-pressure structure, and the coaxial space between the inner and outer pipes has special baffles along it for gas-air mixing for better flame-retention.
