Beschreibung
Zusammenfassung:	FIELD: combustion apparatus. ^ SUBSTANCE: method comprises using two periodically operating burners provided with regenerative heat-exchanging nozzles. Each of the burners provide combustion of gas or discharging the combustion products with their subsequent cooling in the heat-exchanging nozzle. The air for the combustion of gas and discharging the combustion products is supplied through the pipelines, heat exchanging nozzles and gas passages that connect the working space of the furnace with the heat-exchanging nozzles. The combustion regime changes for the regime of discharging the product of combustion and vise versa by connecting the air flow and combustion products by means of valve mounted on the pipelines. A portion of the discharged combustion products is directed to the inlet of the air duct device. The amount of combustion products should be sufficient for the decrease of concentration of oxygen in the air supplied for the combustion of gas down to 13-18%. ^ EFFECT: enhanced efficiency. ^ 1 cl, 3 dwg
