The exothermic fuel members include an essentially ferrous inner core provided with an outer aluminum coating. A gas passage extends internally within the tube adjacent the exothermic fuel members.
Claims15
An exothermic burning rod comprising:
- an elongate external tube means;
- exothermic fuel means extending axially within said tube means, further comprising:
- an essentially ferrous inner core;
- an outer coating of aluminum;
- and
- gas passage means internally extending within said tube means adjacent said exothermic fuel means.
A method of constructing an exothermic burning rod comprising providing an elongate tube formed of a ferrous material and having a first predetermined length and an inner surface, and arraying and arranging exothermic fuel means in the form of a plurality of ferrous wires of a second predetermined length different from said first predetermined length and having a coating of aluminum thereon within said tube and against the inner surface thereof to form a longitudinally extending gas passage through said tube adjacent said exothermic fuel means.
