A mathematical model for the description of axisymmetric swirled flow with diffusion combustion is based on numerical solution of the Reynolds equation with a k–W model of turbulence. The results of numerical and experimental investigations of local and general characteristics of flow, heat and mass transfer, combustion, and NOx formation in an annular combustor with opposite swirled air jets are presented. Satisfactory agreement between calculations and experiments is obtained. The dependences of combustor characteristics versus geometric and operational parameters are generalized.

The results of experimental investigation of the basic parameters of one-burner, 1/18 sector of a full-scale annular combustor of the “Turboatom” GTE-115 gas turbine unit are presented. Specifics of fuel burnup and formation of toxic pollutants in premixed combustion using a pilot diffusion burner are presented. Generalized dependences of combustor characteristics versus flow parameters and an optimized algorithm of combustor loading are illustrated.
