CHARGE AND METHOD FOR MANUFACTURE OF FUEL BRIQUETTES Russian patent published in 2015 - IPC C10L5/10 C10L5/12 C10L5/14 C10L5/22 C10L5/28 

FIELD: heating.

SUBSTANCE: invention relates to a charge containing bituminous coal and binding additives; bituminous coal contains an unburnt ash-slag mixture as a result of coal combustion in boiler houses, at thermal power plants, in domestic stoves, coal benefication wastes, and the following is used as activators: coal-tar resin, resinous wastes of coke-chemical and chemical industry, waste machine oils; aluminium powder in the amount of 1-3 vol % is used as a high-calorific additive, and lime in the amount of 13-18 vol % is used as a binding agent. The invention also relates to a manufacturing method of fuel briquettes from a charge, which involves crushing and mixing of charge components; after mixing is completed, water separation, mixture extrusion, and briquette drying and packaging is performed.

EFFECT: improvement of ecology, economical efficiency of bituminous coal processing, reduction of quantity of wastes and increase of heat amount at coal combustion.
