METHOD FOR OBTAINING FUEL COMPOSITION FOR BOILER PLANT Russian patent published in 2012 - IPC C10L1/32 C10G1/00 

FIELD: oil and gas production.

SUBSTANCE: method for obtaining fuel composition for boiler plant consists in preliminary cleaning of oil sludge from oil and oil product reservoirs that contains 10-20% wt of water due to water excess and mechanical impurities at 70-80°C. Mixing of cleaned oil sludge in quantity 30-70% wt, with residual oil M-100 and wastes of solid fossil fuels semi-coking production - pyroligneous liquor in quantity 0.5-5.0% wt. Water steam is supplied through the obtained mixture at temperature 90-95°C. The mixture emulsification is carried out for 20-30 minutes.

EFFECT: method allows using wastes, reducing energy consumption and obtaining fuel of low viscosity, high stability and resistance to corrosion.
