HIGHLY INFLAMMABLE FUEL BRIQUETTE Russian patent published in 2012 - IPC C10L5/44 

FIELD: power engineering.

SUBSTANCE: briquettes are designed for fireplaces, different domestic stoves, for cooking, heating of residential and domestic premises, to heat railway cars, temporary cabins, etc. A highly inflammable fuel briquette contains the main layer, including a coal-containing component and a binder, and an igniting layer containing nitrate and a binder. The coal-containing component is represented by coal slacks in amount of 30-60%, the binder is paper wastes in amount of 40-70%, and the igniting layer contains potassium nitrate or sodium nitrate in amount of at least 80 wt % of the igniting layer. At the same time the briquette is made with a hole, the area of the cross section of which makes from 25 to 40% from the area of the briquette cross section. Availability of both a flammable component (paper wastes) and an oxidant (potassium or sodium nitrate) in the igniting layer makes it possible for it to easily ignite from low-energy sources of heat (for instance, matches). Availability of a central hole increases completeness of fuel briquette burning and reduces emissions of hazardous substances into atmosphere.

EFFECT: fuel briquette is formed on an extruder, which simplifies and cheapens its manufacturing process.
