| description | Temperature distribution and flue gas emissions in gas turbine combustion chambers have attracted the attention of researchers in recent years. In this study, the combustion chamber temperature distribution and flue gas emission values at different equivalence ratios were determined by diluting the methane flame with Helium at the rate of 20% by volume. Aswirl generator which has high swirl number (1.6) was placed at the burner outlet and the combustor power was kept constant at 3 kW. In this way, the equivalence effect in a swirled combustion was investigated. The following results emerged in the study, in which 0.7, 0.8, 0.9, 1.0, 1.1 values were tested as the equivalence ratio. The results showed that with the increase of the equivalence ratio, the flame temperature and brightness at theburner outlet increased, reaching its maximum at 0.9 equivalence ratio. After this critical value, there was a tendency to decrease in temperature and luminous intensity again. As the distance from the burner axially in the combustion chamber increased, the average temperatures increased with the increase in the equivalence ratio. On the other hand, The CO value in flue gas emissions decrease by half as the equivalency ratio increased from 0.7 to 1.0. |
