초록
An experimental study was performed to confirm the effect of the changing combustor pressure(-30~30 kpa), combustion characteristics were investigated by measuring the local chemiluminescence intensity, the local temperature distribution and emission. In order to investigate combustion ones, the combustor pressure index(P*) was controlled in the range of 0.7~1.3 for each equivalence ratio in the present combustion system, where P* is defined as the ratio of absolute pressure to atmospheric one. The local mean temperature showed the uniform distributions for lower pressure index, which increased with increasing equivalence ratio. The mean OH* chemiluminescence intensity, showed high level for lower pressure index for Φ≥1.0 conditions. EINOx decreased with decreasing pressure index for overall equivalence ratio conditions.
Abstract
An experimental study was performed to confirm the effect of the changing combustor pressure(-30~30 kpa), combustion characteristics were investigated by measuring the local chemiluminescence intensity, the local temperature distribution and emission. In order to investigate combustion ones, the combustor pressure index(P*) was controlled in the range of 0.7~1.3 for each equivalence ratio in the present combustion system, where P* is defined as the ratio of absolute pressure to atmospheric one. The local mean temperature showed the uniform distributions for lower pressure index, which increased with increasing equivalence ratio. The mean OH* chemiluminescence intensity, showed high level for lower pressure index for Φ≥1.0 conditions. EINOx decreased with decreasing pressure index for overall equivalence ratio conditions.
