On the question of increasing the purification efficiency of flue gases from the boiler unit of HEPS Volzhsky automobile plant

The paper considers the measures to suppress emissions of nitrogen and carbon oxides emitted during natural gas combustion, used on the VAZ heat electro-power station territory in Togliatti. The analysis of the quantitative distribution of fuel consumption and pollutant emissions for 2015 - 2019 has been carried out. The description of the process flow diagram of the gas-air duct of the TGME-464 boiler unit (KA No.12) is presented. The possibility of using the method of selective catalytic reduction of nitrogen and carbon oxides on the honeycomb ceramic catalyst surface is considered. The graphical dependences of the volumetric-mass air flow rates, flue gas fuel, specific flow and speed energy on the change in the heat load of the boiler unit are determined. The possibility of using a mathematical model for calculating the change in concentrations and along the length of the catalytic layer depending on the flue gas flow temperature is considered.
