Abstract
An attachment for a torch includes a combustion cone mounted on a fuel delivery tube. The combustion cone bounds a combustion chamber and has an inlet through which fuel from the tube enters the chamber to create a flame when the torch ignites the fuel. The cone diverges away from the inlet and to an outlet to enable the flame to diverge and spread within the chamber. The chamber substantially contains the flame therein. At least one apertured radiator, and preferably, a pair of apertured radiators, is mounted in the chamber in direct contact with the flame, and heated by the flame to a temperature sufficient to cause each radiator to radiate infrared radiation through and past the outlet. A tipping-resistant holder holds a fuel canister of the torch upright when placed on a support surface.
