Abstract
The article provides predictive analysis and calculation of concentrations of benz(a)pyrene, carbon monoxide, ash and coke particles in the combustion products promising coal-fired boiler with ultra supercritical parameters. Furthermore, the article defines emission limit values of benz(a)pyrene depending on the operating characteristics of the boiler PK-37 and types of coal fuel. In order to ensure low-emission combustion of coal the authors of this article provide the optimal temperature levels of use of fuel with high ash content. When the dispersion of carcinogenic emissions to the maximum ground level concentrations, it is proposed time of stay of products of incomplete combustion in the atmosphere until full conversion of toxic substances. The article analyzes of regulation peculiarities of benz(a)pyrene emissions from heat-generating installations in the dispersion of combustion products in air.
