불안정 가스 터빈 연소기에서 부분 예혼합이 화염구조와 NOx 배출 특성에 미치는 영향
Effects of Partial Premixing on Flame Structure and NOx Emission Characteristics in an Unstable Gas Turbine Combustor
초록
본 연구는 연료-공기 혼합정도가 불안정 화염 구조와 NOx 배출 특성에 미치는 영향을 조사하기 위해 대기압, 모형 가스 터빈 연소기에서 실험을 수행하였다. 선회각은
Experiments were carried out in an atmospheric pressure, lab-scale gas turbine combustor to see the effect of partial premixing on unstable flame structure and Nox emission characteristics. The swirl angle is 45 deg., fuel-air mixing degrees were varied 0, 50 and 100% respectively at equivalence ratio ranging from 0.53 to 0.79. The evolution of phased-locked OH chemiluminescence images were acquired with an ICCD. NOx emission characteristics were also investigated at each experimental condition. The effect of the fuel-air mixing degree on the flame structure was obtained from phase-locked
