Claim Text:
1. An attachment for a torch for igniting fuel and air to produce a flame in a burn tube, the attachment comprising: a combustion cone mounted on the burn tube and bounding an internal chamber, the combustion cone having an inlet through which the flame enters the chamber, and an outlet spaced away from the inlet along a longitudinal direction, the outlet being larger in opening size than the inlet, the combustion cone diverging along the longitudinal direction away from the inlet and to the larger outlet to enable the flame entering the chamber to diverge and spread within the chamber along the longitudinal direction; and at least one apertured radiator mounted in the chamber and extending transversely of the longitudinal direction across the outlet, the radiator being positioned in direct contact with, and heated by, the spread flame to a temperature sufficient to cause the radiator to radiate thermal radiation through and past the outlet.
