Abstract
- The transition to low-carbon development, to reduce the negative impact on the environment, mainly affects the energy sector. Natural gas occupies a stable position of the demand of the Unified Energy System of Russia for 2021-2026 in fossil fuel. When natural gas is burned, thermal nitrogen oxides (hereinafter referred to as NOx) are predominantly formed in power-generating boiler of thermal power plants. This article presents the modeling and study of the natural gas combustion process with the organization of flue gas recirculation to the active burning zone on the example of a power-generating boiler of the TGMT-464 type, using the ANSYS Fluent software package. The paper presents a model and graphs of the temperature and NOx content distribution in the active burning zone with a change in the proportion of flue gas recirculation from 0 to 22%. The decrease in the emission of harmful substances is explained by the decrease in the peak flame temperature in the active burning zone, which is the main indicator of the formation of NOx. The decrease in temperature in the active burning zone is explained by an increase in the volume of gases in the combustion zone. The article is intended for postgraduate, candidate for a doctor's degree interested in the development of methods for suppressing the formation of NOx in the combustion products power-generating boiler at TPPs.
