FIELD: chemistry.
SUBSTANCE: method is based on formation and introduction of drainage gases into preliminarily heated mixture of air with auxiliary fuel, ignition and combustion with formation of high-temperature gas flow in flow part of afterburner reaction zone. Emissions of 10% carbon monoxide in mixture with 90% of oxygen are neutralised to concentration less than 6.25 mg/m3 of carbon monoxide in air by oxidation at temperature 870°C÷950°C and absolute pressure 1.5 atm in chamber of hydrocarbon fuel combustion in air with air excess coefficient α=2÷3. Selected ratio of the total consumption of fuel components to consumption of mixture of harmful substances is less than 2.5.
EFFECT: reduction of carbon monoxide emissions lower than the maximum allowable concentration in air by selection of optimal mode of fuel component combustion for burning said emissions and selection of ratio of the total consumption of fuel components to consumption of harmful emissions, supplied to neutralisation.
