Fuel briquette

Abstract

Fuel briquettes based on carbon-containing materials, such as fuel briquettes for household use for heating of living and housekeeping spaces, glass-covered and film-covered greenhouses, especially in those geographic regions where no natural fuels like firewood, coal or turf are available. The fuel briquettes may also be used in chimney fireplaces, portable stoves, boilers, grills and braziers, for heating of railway carriages and accommodation cabins for labor and military personnel. A new binder, namely, Sosnowsky's hogweed, is used, providing environmental improvement and termination of weed infestation of fertile soils due to expansion of Sosnowsky's hogweed. The technical effects are attained by a fuel briquette containing a premix of ground carbon-containing filler and a biomass of ground plants of Sosnowsky's hogweed (e.g., entire plants including leaves, stems, roots and umbels) used as a binder. The briquette is compressed to remove liquid content and then dried.

Claims

1. A fuel briquette comprising: a ground carbon-containing filler mixed in advance with a binder, wherein ground charcoal of 10 to 20 ?m grading fraction is used as the carbon-containing filler, wherein a biomass of ground plants of Sosnowsky's hogweed is used as the binder; and the briquette is compressed to remove liquid content and then dried.

2. The fuel briquette of claim 1, wherein 2% wt of the biomass is used in the fuel briquette.

3. The fuel briquette of claim 1, wherein a wood ash is added to the mixture of the carbon-containing filler and the biomass.

4. The fuel briquette of claim 3, wherein the wood ash is aspen wood ash.

5. The fuel briquette of claim 4, wherein 0.5% wt. of the aspen wood ash is used in the fuel briquette.

6. The fuel briquette of claim 1, wherein the plants are used in ground form, having solid particles of 10 to 20 ?m in size.

7. The fuel briquette of claim 1, wherein the fuel briquette has cylindrical shape with height of 60 mm and diameter of 30 to 36 mm.

8. The fuel briquette of claim 1, wherein entire plants of the Sosnowsky's hogweed, including leaves, stems, roots and umbels, are used for grinding into the binder.

9. A fuel briquette comprising: a ground carbon-containing filler mixed with a binder, wherein ground charcoal of 10 to 20 ?m grading fraction is used as the carbon-containing filler, wherein a biomass of ground plants of Sosnowsky's hogweed is used as the binder, and wherein any liquid content of the briquette is removed after the mixing and the briquette is then dried.

10. The fuel briquette of claim 9, wherein entire plants of the Sosnowsky's hogweed, including leaves, stems, roots and umbels, are used for grinding into the binder.

11. A method of making a fuel briquette, comprising: mixing a ground carbon-containing filler with a binder, wherein ground charcoal of 10 to 20 ?m grading fraction is used as the carbon-containing filler; wherein a biomass of ground plants of Sosnowsky's hogweed is used as the binder; and removing any liquid content of the briquette; and drying the briquette.

12. The method of claim 11, wherein the fuel briquette is dried in a vacuum chamber during 4 to 5 hours at temperature of 50? C.

13. The method of claim 11, wherein the fuel briquette is compressed using a hydraulic press and a molding tool with a straight hole, wherein the molding tool is configured to remove liquid content from the fuel briquette.

14. The method of claim 13, wherein the hydraulic press provides a pressure of 300 to 500 tons for compressing the fuel briquette.

Description

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(1) As one embodiment, the invention is implemented as a fuel briquette of cylindrical shape with height of 60 mm and diameter of 30 to 36 mm. The fuel briquette contains ground charcoal and a biomass of ground plants of Sosnowsky's hogweed used as a binder, and 0.5% wt. of aspen wood ash, mixed in advance and then compressed with removal of liquid content and afterwards dried in a vacuum chamber. The briquette keeps its shape during transportation and burns out in 4 hours with no flame.

(2) The fuel briquette is produced by premixing ground charcoal with a biomass of ground plants of Sosnowsky's hogweed, compressing in a hydraulic press with removing liquid content and then drying in a vacuum chamber during 4 to 5 hours at temperature of 50? C., after which it is ready to use. The fuel briquette burns up from one of its base sides and provides flameless combustion for 4 hours.

(3) Preferably, ground charcoal of 10 to 20 ?m grading fraction is used as the carbon-containing filler.

(4) Preferably, plants of Sosnowsky's hogweed, and optionally entire plants including leaves, stems, roots and umbels, are used in ground form with size of solid particles of 10 to 20 ?m.

(5) Preferably, wood ash is added to the mixture of the carbon-containing filler and the biomass.

(6) Preferably, aspen wood ash is used as the wood ash.

(7) Preferably, 2% wt. of the biomass of ground plants of Sosnowsky's hogweed is included into content of the fuel briquette.

(8) Preferably, 0.5% wt. of aspen wood ash is included into content of the fuel briquette.

(9) Preferably, the fuel briquette is compressed using a hydraulic press and a molding tool with a straight hole, the molding tool configured to remove liquid content.

(10) Preferably, the fuel briquette has cylindrical shape with height of 60 mm and diameter of 30 to 36 mm.

(11) Preferably, the fuel briquette is compressed using a hydraulic press providing pressure of 300 to 500 tons.

(12) Preferably, the fuel briquette is dried in a vacuum chamber during 4 to 5 hours at temperature of 50? C.

(13) Thus, the technical effect is obtained. Novelty and inventive step of the invention are assured by including Sosnowsky's hogweed into fuel briquettes as a binder. This resource is widely available in certain locations, but it was not used for this purpose before. This approach provides resource saving, environmental improvement and termination of weed infestation of fertile soils due to huge expansion of Sosnowsky's hogweed in the world.

(14) Having thus described a preferred embodiment, it should be apparent to those skilled in the art that certain advantages of the described method and apparatus have been achieved.

(15) It should also be appreciated that various modifications, adaptations, and alternative embodiments thereof may be made within the scope and spirit of the present invention. The invention is further defined by the following claims.
