Abstract (en)
A solid fuel briquette is constructed from a mixture of anthracite duff and petroleum coke held together by bitumen or some other hydrocarbon based binder, the mixture having been pressed to form the solid fuel briquette. The final product can incorporate the constituents in the ratios of 10% to 60% of petroleum coke, 1% to 10% of the binder, with the balance being anthracite duff, all proportions being by weight. A preferred non-smokeless fuel briquette is formed from about 25% petroleum coke, 7% bitumen binder and 68% anthracite duff, by weight. A smokeless fuel briquette may be formed from about 25% petroleum coke, 5% bitumen binder and 70% anthracite duff, subsequently oxidised to reduce the binder content to about 1%.
