FIELD: power engineering.
SUBSTANCE: invention relates to the method for production of coal briquettes from coal slurry and coal fines with a binder - an aqueous solution of polyelectrolyte - a flocculant on the basis of a polyacrylamide (PAA). As an intensifying additive to increase adhesion as a charge is compressed in process of pressing, the initial solution of PAA is complemented with water-soluble surfactants from the class of polyethers based on propylene glycol. Coal briquettes are used for communal-domestic and technological purposes.
EFFECT: higher efficiency of application.
