The article presents the results of numerical modeling of the effect of various fuel supply options on the combustion processes behind the turbine profiles. The article considered three options for fuel supply. In the first option, (a) the fuel is supplied to the wide side of the profile; in the second option, (b) the fuel is sprayed directly into the recirculation zone formed between the plate and the profiles; in the third option, (c) the fuel is sprayed from the convex (back) part of the profile. On the basis of the analysis performed, it can be concluded that the profiles of the blades have rather high stabilization parameters. The best performance has the option of supplying fuel from the back of the turbine profile. This option provides the minimum concentration of nitrogen oxides, with all other factors being equal.
