METHOD TO PRODUCE FUEL BRIQUETTES Russian patent published in 2014 - IPC C10L5/06 C10L5/10 C10L5/14 C10L5/28 

FIELD: power engineering.

SUBSTANCE: invention includes mixing of ground solid fuel with a binder, briquetting of the mix under pressure, where the ground solid fuel is coke dust with particle size of less than 1 mm, and the binder is coking sludge in the amount of 8.0-10% to the weight of coke dust, the die mould is first heated to 40-50°C, and briquetting of the mix under pressure is carried out under pressure in stages, for this purpose they first set load of 5-6 atm, with a delay of 3-5 min and then up to 15 atm with delay at maximum load of 3-5 min. The produced briquettes maybe used as fuel for burning in domestic and industrial furnaces, as well as for coking in chemical-recovery and metallurgical industry.

EFFECT: production of fuel briquettes of higher strength, improved environmental situation in coal processing regions, reduced prime cost of fuel briquettes.
