Journal of Combustion, Volume 2023, Issue 1, 2023., 2023 The article contains a comparative analysis of two types of burners used in different methods of fuel‐air mixture preparation: (1) vortex mixing and (2) mixing with transverse jets. The analysis was carried out in order to determine which one of the two burning devices is more efficient and has better environmental performance. In device no.
