A torch apparatus for consuming a material having a fuel load that produces heat and a source of oxygen when burned, and a plurality of slots having interstitial spaces therebetween for allowing longitudinal flow of fluid along the torch apparatus without interfering with the flow of fluid through the slots. The slots are oriented such that the heat and source of oxygen are provided to a material that is at least partially consumed when exposed to heat and oxygen, to thereby cause destruction of an object containing the material or disengagement of the object such that it falls into the wellbore.
