Abstract

Claims (22)

1 . A fuel pack for a solid fuel fire comprising:

a quantity of fuel pellets of uniform diameter and having an accelerant; and

an outer wrapper at least partially containing the fuel pellets;

wherein the outer wrapper comprises an outer paper layer backed by a polymer liner containing the quantity of fuel pellets within an interior thereof adjacent to and contacting the fuel pellets, the interior containing no other combustible material beyond the quantity of fuel pellets;

wherein the outer wrapper is ignitable to instigate combustion of the fuel pack such that substantially all of the quantity of fuel pellets and all of the outer wrapper burn in a controlled manner;

wherein the polymer liner comprises a coextruded material having a Nylon layer interposing first and second polyethylene layers with the Nylon layer being adjacent to both the first and second polyethylene layers; and

wherein the outer paper layer forms an outside surface of the outer wrapper;

wherein the outer paper layer comprises a Kraft paper having a weight from 25 to 50 pounds.

2 . The fuel pack of claim 1 , wherein the accelerant comprises a hydrotreated light distillate.

3 . The fuel pack of claim 2 , wherein the quantity of fuel pellets has a bulk density between about 40-46 lbs/ft3.

4 . The fuel pack of claim 3 , wherein the quantity of fuel pellets has a moisture content of less than about 8.0%.

5 . The fuel pack of claim 4 , wherein the quantity of fuel pellets has an ash content of less than about 1%.

6 . A fuel pack consisting of:

an outer wrapper consisting of an outer paper layer backed by a polymer liner and arranged to form an interior volume bounded by the polymer liner;

a quantity of fuel pellets contained within the interior volume at least some of which are in contact with the polymer liner; and

an accelerant consisting of a hydrotreated light distillate applied to the quantity of fuel pellets;

wherein the outer wrapper, by exposure to flame, exposes the quantity of fuel pellets for ignition; and

wherein the liner consists of a coextruded arrangement with a Nylon layer interposing first and second polyethylene layers with the Nylon layer being adjacent to both the first and second polyethylene layers;

wherein the quantity of fuel pellets consist of a pelletized hardwood having a pellet diameter of a uniform size.

7 . The fuel pack of claim 6 , wherein a ratio of accelerant to mass of pelletized hardwood is about 7%.

8 . The fuel pack of claim 6 , wherein the outer paper layer comprises a 25-pound Kraft paper.

9 . The fuel pack of claim 6 , wherein the liner has a thickness of about 2.5 mil.
