Abstract
An exothermic burning rod includes exothermic fuel members extending axially within an elongate, external tube. 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.
Claims6
An exothermic burning rod configured for securement to a similarly constructed exothermic burning rod, said exothermic burning rod comprising an elongated external tube means, exothermic fuel means located within said tube means and a gas passage means extending through said tube means, said tube means having a first open end and a second open end between which said gas passageway means extends, said first open end of said tube means being of a first external diameter, said second open end of said tube means being of a second internal diameter, said first external diameter being substantially the same as said second internal diameter, said first open end of said tube means being arranged to be frictionally fit and secured within the second open end of the tube means of the similarly constructed burning rod.
The combination of a pair of exothermic burning rods secured to each other, each of said exothermic burning rods comprising an elongated external tube means, exothermic fuel means located within said tube means and a gas passage means extending through said tube means, said tube means having a first open end and a second open end between which said gas passageway means extends, said first open end of said tube means being of a first external diameter, said second open end of said tube means being of a second internal diameter, said first external diameter being substantially the same as said second internal diameter, said first open end of said tube means of one of said pair of rods being frictionally fit and secured within the second open end of the tube means of the other of said pair of burning rods.
