Effects of Partial Premixing on Flame Structure and NOx Emission Characteristics in an Unstable Gas Turbine Combustor
불안정 가스 터빈 연소기에서 부분 예혼합이 화염구조와 NOx 배출 특성에 미치는 영향
Abstract
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
