“…The efficiency of reducing NO X from the supply of recirculation gases directly to the burner device is affected by the place of the entry and the configuration of the burner porthole, which affect the intensity of the mixing processes of the media flowing from the burner channels. This is indicated in [6] by the form of the fields of the composite jet at the cut of the burner embrasure. The lowest concentration of nitrogen oxides in this case, for swirl burners, is observed in the burner with a separate pipe for supplying recirculation gases.…”

Currently, NOX emission requirements for thermal power plants and power equipment are being tightened. Regime and technical measures are being developed to improve the efficiency of fuel combustion in boilers. Due to the high cost of field studies, and in some cases the impossibility of conducting them, mathematical modeling tools allow one to work out technical and tactical measures. In this paper, the multidisciplinary STAR-CCM+ platform with GMU-45 type burners is used to simulate the combustion of gaseous fuel in a digital model of an energy boiler of the type TGME-464. By conducting numerical experiments, the possibility of reducing NOX emissions by using flue gas recirculation is considered, and the efficiency of burner devices is compared when using different embrasure configurations.

“…The works [35,36] present the results of a study of the influence of the design of the burner embrasure on the nature of combustion, performed by numerical simulation using CFD methods. There is a great potential for reducing harmful emissions by optimizing the geometry of the burner embrasure.…”
