METHOD OF MAKING FUEL BRIQUETTES Russian patent published in 2015 - IPC C10L5/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing fuel briquettes, which includes mixing crushed solid fuel with a phenol-alkaline resin in amount of 1.7-1.8% of the weight of coke fines and an ester curing agent in amount of 22-28% of the weight of the resin, pressing the obtained mixture and moulding fuel briquettes, wherein the coke fines with particle size of 0.6-3 mm and moisture content of up to 3% with the phenol-alkaline resin and ester curing agent are mixed in a vortex mixer, and the obtained mixture is pressed by rigid auger extrusion at pressure of 7-8 mPa, followed by moulding a bar which is then broken down into pieces with length of 100-150 mm.

EFFECT: improved efficiency of the process of producing fuel briquettes while simultaneously reducing power consumption and expenses, obtaining high-strength fuel briquettes, high calorific capacity, gas permeability and heat resistance.
