초록

초음파 진동자에 의해 미립화된 탄화수소계 액체연료를 분사하는 버너(burner)의 연소특성을 고찰하기 위한 실험이 수행되었다. DSLR 카메라를 이용하여 미립화된 액체연료의 화염형상을 획득하였고, 이미지 후처리를 통해 그 구조를 면밀히 분석하였다. 또한 열전대를 이용하여 연소장의 온도도 측정하였다. 그 결과, 버너 내부에 주입되는 수송가스의 질량유량과, 초음파 진동자의 진폭에 비례하여 화염의 크기가 커졌다. 또한, 버너 작동조건의 변이에 따른 연소장의 온도분포를 측정, 제시한다.

An experimental study was performed to investigate the combustion characteristics of the liquid hydrocarbon fuel atomized by an ultrasonic oscillator. Configuration of the flame was caught by the DSLR camera, and images were analyzed in detail through a post-processing. Temperature of the flame zone was measured using thermocouple. It is resulted that the flame area is proportional to the mass flow rate of carrier gas as well as the voltage applied to the ultrasonic oscillator. Temperature of the flame zone is measured and analyzed according to variation in the operating condition of the burner, too.
