FIELD: fuel briquettes for domestic and industrial use in boiler houses and railway car furnaces.
SUBSTANCE: proposed fuel composition contains 20-65% of waste of leather production process; 10-30% of hydrocarbon sludge; 0-20% of wood waste; the remainder being peat. Hydrocarbon sludge contains up to 200 g/kg of petroleum products. Waste of leather production process is used in form of leather dust, leather cuttings and leather chips. Fuel composition may also include waste of wood-pulp and paper industry, weaving and sewing processes in the amount of up to 10 mass-%. Proposed fuel enhances utilization of sludge of car repair plants, engineering plants and other works containing up to 200 g/kg of petroleum products.
EFFECT: enhanced efficiency.
