Formation and reduction of benz(a)pyrene and nitrogen oxides emissions in boilers with vortex gas flow

Improving the Efficiency of Fuel Combustion with the Use of Various Designs of Embrasures

“…During the reconstruction of the burner devices of steam boilers in operation at TPPs during technical re-equipment and reconstruction, they can not only achieve a reduction in NO X emissions, but also simultaneously improve the technical and economic indicators of the legal boiler, as well as increase the safety of its operation [14]. Furthermore, an important condition is to ensure high turbulence of combustion processes [15]. When modeling furnace processes, it is required to know the temperature of adiabatic combustion of fuel, the attenuation coefficient of radiation by the furnace medium, the emissivity of the furnace, considering the size of the radiating layer, the coefficient of thermal efficiency of the furnace screens, the resulting Boltzmann number, and the final calculated value of the gas temperature at the outlet of the furnace.…”
