Currently, ANSYS Fluent software is widely used as an alternative engineering tool for describing the physical processes occurring in the furnace and gas burners of the boiler. In the work, the technology of preparation and characteristics of fuel combustion of the boiler KVTK-100-150-4 of the Ekibastuz CHPP are investigated. Calculations of the energy characteristics of the combustion process in the combustion chamber have been carried out. A three-dimensional mathematical model of the combustion process was carried out using the ANSYS Fluent software. The analysis of methods for reducing the formation of harmful substances.
