Abstract
A fuel delivery system and burner for a torch. Fuel passes from a regulator into a tube that extends through the path of a flame that is produced by the burner. The tube preferably is shaped into a coil around the area of the flame so that the coil is heated by the flame. The heated coil assures that liquid fuel in the coil is vaporized as it passes through the coil. In addition, the coil may act as a flame spreader. A burner tube includes an internal passage and an outer passage. Fuel vapor flows through each of these passages, and escapes the burner tube at a distal end. The outer flow of gas is slow, and does not aspirate air, causing the flame to remain attached to the burner and to burn yellow. The inner flow of gas adds velocity, helping the burner flame to be wind resistant.
