FUEL BRICK Russian patent published in 2010 - IPC C10L5/10 C10L5/12 C10L5/14 

FIELD: oil and gas production.

SUBSTANCE: fuel brick includes crushed charcoal with particle size of 0.05 mm to 5 mm, water and bonding agent chosen from amylose, carboxymethyl cellulose, or sodium hydrosilicate or sapropel at the following component ratio, wt %: amylose of 4 to 8, or carboxymethyl cellulose of 4 to 8, or sodium hydrosilicate of 2 to 5, or sapropel of 2 to 10, water is less than 3, crushed charcoal - the rest up to 100, and density of fuel brick is 500 kg/m³ to 900 kg/m³. The proposed technical solution enlarges range of solid fuel and provides development of ecologically clean fuel bricks with high energy and strength characteristics.

EFFECT: increasing combustion heat and decreasing ash content of fuel bricks, increasing their strength at throwing, improving ignition processes and catalytic combustion of fuel bricks.
