FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. Method of burning in the furnace includes the burning of fuel in the furnace for the formation of gaseous combustion products containing NOx, and alternately passing NOx-containing gaseous products from the furnace to the cooled first regenerator and through it to heat the first regenerator and to cool said combustion gases, the transmission of the first part of these cooled gaseous products of combustion from the specified first regenerator and fuel in the heated second regenerator, conducting in the second regenerator endothermic reaction of gaseous products of combustion and fuel to reduce NOx in these gaseous products of combustion to nitrogen and for the formation of synthetic gas containing hydrogen, CO and the specified nitrogen, passing said syngas from the second regenerator to the kiln and burning it in this kiln with simultaneous transmission of the remaining part of said gaseous combustion products from said first regenerator to the exhaust pipe, and passing the gaseous combustion products containing NOx from the furnace to the cooled second regenerator and through it to heat the second regenerator and to cool said gaseous combustion products, the transmission of the first part of these cooled gaseous products of combustion from the specified second regenerator and fuel in the heated first regenerator, conducting in the first regenerator endothermic reaction of gaseous products of combustion and fuel to reduce NOx in said gaseous products of combustion to nitrogen and to form synthetic gas containing hydrogen, CO and the specified nitrogen, passing said syngas from the first regenerator to the kiln and burning it in this kiln with simultaneous transmission of the remaining portion of said gaseous products of combustion from said second regenerator to the exhaust pipe.
EFFECT: invention reduces NOx emissions.
