FLAKY FUEL BRIQUETTE Russian patent published in 2012 - IPC C10L5/14 C10L5/02 C10L5/38 

FIELD: power engineering.

SUBSTANCE: flaky fuel briquette comprises the main part, including coal and a binder, and an ignition part, and has longitudinal holes in the entire volume of the briquette. The ignition part is located on the end surface of the briquette coaxially with holes in such a manner that the larger part of the all holes cross section is on the ignition part. The area of the ignition part cross section is less than the area of the briquette cross section and is made as increasing from the end surface of the briquette to its centre. At the same time the ignition part may be made in the form of a truncated cone, in the form of coaxial cylinders contacting with each other, besides, the smaller cylinder is arranged one above the other or in the form of a voluminous multiple-beam star.

EFFECT: reliable ignition and burning of the ignition and main parts, higher reliability of adhesion between the main and the ignition parts, the fuel briquette differs with high completeness of fuel mass burning and low hazardous emissions to the atmosphere.
