NUMERICAL MODELING OF BENZ(A)PYRENE EMISSIONS DISPERSION FROM FUEL COMBUSTION INSTALLATIONS

Abstract
The paper is devoted to the numerical modeling of benz(a)pyrene emissions dispersion in air. For boilers of low heat capacity that combust coal and natural gas, the paperdetermines the limiting concentration levels of benz(a)pyrene in the combustion products and analyzes the influence of operating factors (heat load, the excess air ratio) on the formation of the final content of benz(a)pyrene in flue gases.
In this paper, the authors define the coefficients of turbulent diffusion, the maximum distance for observation of maximum ground level concentrations when the dispersion of gaseous emissions from the combustion of coal fuel and natural gas. Prediction of ground concentration of benz(a)pyrene allows steps to determine and optimize the size of the sanitary protection zone of the heat-generating enterprise, which is particularly important in dense urban areas.
