The article presents the results of experimental-theoretical study of natural gas and fuel oil combustion in steam power boilers, impact of operation and constructive factors on emissions of pollutants discharged with flue gases and methods of NOx reduction in flue gases, their recovery to the molecular nitrogen.

In the process of fuel combustion in furnaces of steam boilers a variety of toxic substances are formed, which are then released into the atmosphere together with flue gases. Such substances in this case include, firstly, nitrogen and sulfur oxides, and, secondly, a number of products of incomplete combustion, in particular, polycyclic aromatic hydrocarbons (PAHC).
