Abstract
The invention relates to the field of heat power engineering and metallurgy for use in heat process units in metallurgical and machine engineering complex, in co-generation units and internal combustion engines. Technical results: lower losses of heat with exhaust gases, lower concentration of nitrogen oxides (NO-NO and NO) in exhaust gases. The method comprises ignition and burning of fuel (16), cooling of the exhaust gas (5) in a heat exchanger (3), division of the exhaust gas (5) into a main first recirculating (6) portion and a second disposed (7) portion, mixing of the main first recirculating (6) portion with technical purity grade oxygen (10) in the amount of 26.58-42.86% of the exhaust gas (5) main first recirculating (6) portion volume, for replacement of nitrogen contained in the combustion chamber (13) atmosphere. The obtained combustion gas (11) flow is transferred to a burner device (12) of the combustion chamber (13). Balance is maintained between the mixture of technical grade oxygen (10) with the exhaust gas (5) main first recirculating (6) portion and the fuel (16); the nitrogen oxide emission becomes substantially reduced and amounts to 4.30-12.5 ppm in the exhaust gases.
