FIELD: solid fuels.
SUBSTANCE: process consists in that for fabrication of robust brown-coal briquettes, which can be used as fuel for combustion in household and industrial furnaces, coal is first crushed and classified until fineness less than 6 mm, after which household polyethylene waste obtained through cutting polyethylene film into pieces less than 7 mm long is added to coal being briquetted in amounts of 6-7% of the weight of dry coal. Resulting mix is then heated to 90-130°C and compacted into briquettes characterized by mechanical strength 5.5 MPa.
EFFECT: improved robustness of briquettes and partially solved polyethylene waste disposal problem.
