Abstrakt: Computational experiments were carried out using three-dimensional computer modeling methods to determine the effect of various burner arrangements and the method of fuel mixture supply on the main characteristics of heat and mass transfer processes (flow aerodynamics, temperature fields, concentration fields of combustion products) throughout the entire volume of the combustion chamber of a power boiler and at its outlet. It is shown that the use of vortex burners with a swirl of the air mixture flow allows improvement of metabolic processes in the combustion chamber and reduces emissions of harmful substances into the atmosphere both during traditional fuel combustion and at reduced boiler load (partial shutdown of burners).
