Abstract

A compressed fuel product, for example a firelog or other like product, comprises a material comprising a flax straw derivative, for example flax shives or other material derived from flax, which is compressed into a solid body. The material is bonded together under pressure into the solid body solely by natural lignin in the flax straw derivative.

Claims

1. A compressed fuel product comprising a material compressed into a solid body, the material comprising a flax straw derivative.

2. The product according to claim 1 wherein the material primarily comprises a flax straw derivative.

3. The product according to claim 1 wherein a majority of the material comprises a flax straw derivative.

4. The product according to claim 1 wherein the material consists only of a flax straw derivative.

5. The product according to claim 1 wherein the flax straw derivative consists only of flax shives.

6. The product according to claim 1 wherein the material consists only of flax shives.

7. The product according to claim 1 wherein the material in the solid body is bonded together solely by natural lignin in the flax straw derivative.

8. The product according to claim 1 wherein the solid body has a specific gravity greater than 1.

9. The product according to claim 1 wherein the solid body has a specific gravity near 1.25.

10. The product according to claim 1 wherein the solid body is formed in the shape of a firelog.

11. A method of forming a compressed fuel product comprising providing a material comprising a flax straw derivative and compressing the material into a solid body.

12. The method according to claim 11 wherein the material primarily comprises a flax straw derivative.

13. The method according to claim 11 wherein a majority of the material comprises a flax straw derivative.

14. The method according to claim 11 wherein the material consists only of a flax straw derivative.

15. The method according to claim 11 wherein the flax straw derivative consists only of flax shives.

16. The method according to claim 11 wherein the material consists only of flax shives.

17. The method according to claim 11 including bonding the material together in the solid body solely by natural lignin in the flax straw derivative.

18. The method according to claim 11 including compressing the material until the solid body has a specific gravity greater than 1.

19. The method according to claim 11 including extruding the material through an extruder having a screw press and heating the material as it is extruded solely by friction generated from rotating the screw press.

20. The method according to claim 11 including forming the solid body in the shape of a firelog.
