Abstract

A study was conducted to apply open-loop control to the combustion instability in a dump combustor using gaseous hydrocarbon fuels. Control power and frequency were varied by employing a loudspeaker under combustion conditions with similar characteristic chemistry times of the fuels. In the case of open-loop control where the frequency was identical to the combustion instability frequency, the open-loop control power affected the control performance. Results obtained from conducted open-loop control tests, where the frequency was different from the combustion instability frequency, show that setting the open-loop control frequency similar to the combustion instability frequency is effective.

기체 탄화수소 연료를 사용하는 덤프 연소기의 연소불안정에 개루프 제어를 적용하는 연구를 수행하였다. 연료들의 특성화학시간이 유사한 연소조건에서 음향 발생기를 이용하여 제어 출력과 주파수를 변화시켰다. 연소불안정 주파수와 동일한 주파수의 개루프 제어에서는 음향 발생기의 출력이 제어성능에 영향을 주었다. 연소불안정 주파수와 다른 주파수의 개루프 제어결과로부터 개루프 제어주파수는 연소불안정 주파수와 유사하게 설정하는 것이 효과적임을 알 수 있었다.
