The article presents the results of numerical simulation of the influence of the temperature level in the zone of active combustion in the contents of nitrogen oxides and benz(a)pyrene in the combustion products of cracking of fuel oil for the boiler BKZ-420-140 NGM operating under boost. Obtained important characteristics of the combustion process for regulation of the specific release of toxic substances in flue gases. Processing of the obtained simulation results allowed us to obtain new mathematical correlations to calculate the concentration of benz(a)pyrene in exhaust gases in an indirect way based on the content of nitrogen oxides in the combustion products. Developed mathematical relationships can be used in the practice of commissioning actions for configuration of operating modes of boiler plants with minimal emissions of harmful compounds into the atmosphere.
