CHEMICALLY POLLUTED LIQUID FUELS ECOLOGICALLY SAFE UTILIZATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC F23G7/05 F23D11/00 

FIELD: environmental protection.

SUBSTANCE: invention relates to the liquid combustible substances burning technology, and can be used for the safe disposal of fuels of unknown chemical and different fractional composition. Method comprises ignition on clean fuel, heating of the fuel mixture, gas-phase combustion at temperatures above 900 °C, fuel mixture components afterburning, the flue gases cleaning of mechanical particles, the flue gases cooling. At that, the fuel mixture is continuously homogenized, the fuel-air mixture composition does not change depending on the mechanical impurities presence in the fuel mixture, fuel mixture decontaminated components residence time in the high temperature zone is increased due to the combustion products partial recycling to the burner input, which raises the temperature at the burner input and allows to obtain the burning temperature of more than 900 °C, atmospheric air access to the high temperatures zone is regulated in order to minimize the amount of the air nitrogen oxidation products.

EFFECT: technical result is the energy-efficient, environmentally safe disposal of chemically contaminated liquid fuels of different fractional composition containing viscous fractions and mechanical impurities.
