Abstract

A fuel package comprising a biomass fire-log bound by an adhesive consisting of a starch and a hydroxide and at least one ignition aid is provided along with a method of manufacturing the same.

Claims (15)

1. A fuel package comprising a biomass fire-log bound by an adhesive consisting of a starch and a hydroxide and at least one ignition aid, wherein the at least one ignition aid is either pressed directly into a depression in the fire-log or is placed into a cup that is disposed within the depression in the fire-log.

2. The fuel package according to claim 1 , wherein the at least one ignition aid is a natural wax that is mixed with a fibrous combustible material.

3. The fuel package according to claim 2 , wherein the fibrous combustible material is selected from the group consisting of saw dust, planer dust, wood fibers, wood shavings, shredded cardboard, charcoal, agricultural waste, coal, and paper.

4. A fuel package comprising a biomass fire-log bound by an adhesive consisting of a starch and a hydroxide and at least one ignition aid, wherein the fire-log is broken into two or more pieces in the direction of the fire-log's length or width and the at least one ignition aid is placed between the two or more pieces.

5. The fuel package according to claim 1 , wherein the biomass fire-log comprises a composition of combustible biomass materials; the biomass fire-log having a moisture content from about 8% to about 20%.

6. The fuel package according to claim 1 , wherein about 5% to 20% of the starch content is gelatinized.

7. The fuel package according to claim 6 , wherein the starch is formed from a starch source capable of reacting with the hydroxide, the starch source being at least one of wheat, oats, rice, corn, wheat middling, wheat waste, and wood.

8. The fuel package according to claim 6 , wherein the hydroxide is at least one of an alkali metal hydroxide, an alkaline earth hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide, lithium hydroxide, and caustic soda.

9. The fuel package according to claim 1 , wherein the adhesive forms a substantially continuous outer shell around an exterior portion of the biomass fire-log.

10. The fuel package according to claim 9 , wherein the adhesive is lignin.

11. The fuel package according to claim 1 , wherein the biomass fire-log comprises about 90% to 95% of the combustible biomass materials and about 5% to 10% of the adhesive by weight.

12. The fuel package according to claim 1 , wherein the biomass fire-log comprises about 69% to 98% of the combustible biomass materials, about 1% to 30% of the starch, and less than 1% of the hydroxide by weight.

13. The fuel package according to claim 5 , wherein the moisture content of the biomass fire-log is about 12% by weight.

14. A fuel package comprising a biomass fire-log bound by an adhesive consisting of a starch and a hydroxide and at least one ignition aid, wherein the fuel package further comprises an additive selected from the group consisting of a popping additive and a colorant.

15. The fuel package according to claim 14 , wherein the colorant is a coating applied to the popping additive.
