Abstract

[Object] To provide a solid fuel which comprises a binder, a form retaining agent and a vegetable oil-containing substance in a balanced manner, has a stable calorific value and suppresses the production of carbon dioxide.

[Solution] A solid fuel formed from a mixture of a binder, a form retaining agent and a vegetable oil-containing substance, wherein the amount of the binder is 1 to 85 parts by weight, the amount of the form retaining agent is 1 to 55 parts by weight, and the amount of the vegetable oil-containing substance is 10 to 85 parts by weight based on 100 parts by weight of the mixture, and the mixture is molded.

Claims

1. A solid fuel which is formed from a mixture of a binder (component A), a form retaining agent (component B) and a vegetable oil-containing substance (component C), wherein the amount of the component A is 1 to 85 parts by weight, the amount of the component B is 1 to 55 parts by weight, and the amount of the component C is 10 to 85 parts by weight based on 100 parts by weight of the mixture, and the mixture is compression molded.

2. The solid fuel according to claim 1, wherein the total amount of the components A and B is 15 to 90 parts by weight based on 100 parts by weight of the mixture.

3. The solid fuel according to claim 1, wherein the amount of the component C is 10 to 80 parts by weight based on 100 parts by weight of the mixture.

4. The solid fuel according to claim 1, wherein the weight ratio of the component A to the component B is 1:

25 to 85;

1.

5. The solid fuel according to claim 1, wherein the binder (component A) is starch derived from sea alga.

6. The solid fuel according to claim 1, wherein the form retaining agent (component B) is natural rubber.

7. The solid fuel according to claim 1, wherein the vegetable oil-containing substance is the fruit seed of Ricinus communis or Jatropha curcas, or a pulverized product thereof.

8. The solid fuel according to claim 1 having an average size of 10 to 100 cm³ each.

9. The solid fuel according to claim 1 which is prismatic or cylindrical in shape.

10. The solid fuel according to claim 1 having an apparent specific gravity of 0.3 to 0.6 g/cm³.

11. The solid fuel according to claim 1 having a calorific value of 20 to 30 MJ/kg.

12. The solid fuel according to claim 1 which is used for thermal power generation.
