Abstract
Manufactured fuel articles having, as a first component, an inner core of a primary fuel element, and as a second component, a combustible covering layer on the primary fuel element. In some embodiments, the covering layer is preferably at least about a nominal 1.5 millimeters thick, with a preferred thickness being at least about 3 millimeters. In other embodiments, the fuel article may be described as a primary fuel element with a combustible covering layer, wherein the primary fuel element comprises a substantial portion of at least one of the ends, and the covering layer and the primary fuel element are in interfacial contact about a majority of the area of their facing surfaces. In still other embodiments, the fuel articles of the invention are described as a primary fuel element and a combustible covering layer in interfacial contact with the fuel element, and wherein the composition of the covering layer differs substantially from the composition of the primary fuel element and comprises a thermoplastic material and pulp fiber. The invention further comprises methods of producing manufactured fuel articles, including, as one method, extrusion coating of the covering layer onto a previously formed primary fuel element, and, as another method, coextruding the primary fuel element and the covering layer together.
