FIELD: oil and gas industry.
SUBSTANCE: fuel for boiler plant includes heavy oil fraction, stabiliser and oil sludge containing 10 - 20% of water, from oil and oil-product reservoirs. As stabiliser there used is shale oil processing byproduct - polymers with molecular weight of 5000-7000, which contain of not more than 0.05% of sulphur and which are soluble in tar oil. Fuel component ratio, wt %: oil sludge 30-70; polymers 3-10; heavy oil fraction is the rest.
EFFECT: high fuel stability at increased water content; calorific capacity is increased; utilisation of oil processing waste and shale oil processing byproducts.
