METHOD OF MAKING FUEL BRIQUETTES Russian patent published in 2013 - IPC C10L5/44 C10L5/00 C10L5/14 

FIELD: chemistry.

SUBSTANCE: method of making fuel briquettes involves grinding combustible solid components, mixing with binder, pressing and drying the briquettes. The method is characterised by that the combustible solid components used are recycled ballistit-type gun powder or non-recoverable wastes from powder production, ground on a modernised disk mill to particle size of 0.5-1.0 mm, and activated charcoal screenings, ground on a double-roll crusher to particle size of less than 4.0 mm, and mixed in 8.0-10.0% aqueous solution of polyacrylamide binder or a sodium salt of carboxymethyl cellulose in a continuous or periodic action mixing device with horizontal mixers, followed by pressing into fuel briquettes on a shaft pelleting press; the formed briquettes are dried with air on a three-section belt drier at temperature 100…105°C for 3 hours, cooled and then dry-cured for three days.

EFFECT: wider raw material base for making fuel briquettes, environmentally safe recycling of discarded gun powder, ballistit wastes and activated charcoal screenings not suitable for use as an adsorbent, high energy output and calorific capacity of the fuel briquettes.
