METHOD OF PRODUCTION OF SOLID FUEL BRIQUETTES Russian patent published in 2005 - IPC

FIELD: production of solid carbonaceous fuel.

SUBSTANCE: the invention is pertaining to the method of production of solid fuel briquettes and may be used at enterprises producing a household fuel. The method provides for mixing of slack coal (sludge cake) with the diameter of fragments of 0.05-0 mm with a mass share a moisture of 16-17 % and with 5 % (23-34 %) of water solution of a cationic polyelectrolyte, compaction of a charge mixture by a hydraulic press at the pressure of 340 kg/cm² and the thermal treatment at the temperature of t=150°C within 30 minutes. The invention allows to reduce pollutants emissions into the aerosphere at incineration of the solid fuel briquettes that reduces the negative effect on the natural environment and also to exclude the usage of an expensive undersized coke.

EFFECT: the invention ensures reduction of the contaminants emissions into the aerosphere at incineration of the solid fuel briquettes and reduction of the negative effect on the natural environment and also to exclude the usage of the expensive undersized coke.
