Abstract
The article presents the results of numerical simulation of the influence of the characteristic temperature of the torch zone of active burning on concentrations of PAHs, represented by benz(a)pyrene in flue gases of coal-fired boiler BKZ-75-39 FB. The research of the intensity of effect of adiabatic temperature on the distribution of heat exchange in furnace of boiler device. The degree of change of absorption capacity of the combustion environment in terms of the effects of the dimensionless gas temperature at the exit from the zone of active combustion. Estimated concentrations of benzpyrene within the temperature zone (less than 1000 K) dust-coal torch. Based on the obtained results we determined the functional dependence of the content of benz(a)pyrene in exhaust gases of the boiler BKZ-75-39 FB from the dimensionless temperature of the combustion products at the exit of the combustion chamber.
