APPROBATION OF THE METHOD FOR ESTIMATION OF CARBON MONOXIDE EMISSIONS FROM GAS TURBINE COMBUSTORS USING A CHEMICAL REACTOR MODEL WITH TRACKING “LEAN” FUEL-AIR MIXTURE JETS

Abstract

The article describes the main stages of the methodology for calculating carbon monoxide (CO) emissions from the combustion chambers of gas turbine engines using a reactor model developed on the basis of three-dimensional modeling results. The peculiarity of the technique is in identifying and tracking low-temperature "lean" jets of air-fuel mixture. This makes it possible to take into account the heterogeneity of the composition of the burning mixture in more detail and, accordingly, to improve the accuracy of estimating CO emissions. The results of approbation of the proposed calculation method are presented on the example of estimating CO emissions from the experimental single-burner compartment of the combustion chamber of a ground-based gas turbine engine. The discrepancy between calculations and experiment was about 7–23 %.
