Abstract

Combustion characteristics of industrial radiant tube (RT) burners with forced oscillating combustion technology are investigated using a real-scale (125,000 kcal/h) industrial RT burner facility in both laboratory and field tests. Three different types of industrial RT burners using a by-product gas from the iron-and-steelmaking process are examined in a laboratory facility equipped with a W-type RT. During the field tests, an industrial RT burner is characterized in a large facility equipped with multiple RTs. Their performance and emission controls are investigated under diverse operating conditions. The feasibility of the forced oscillating combustion technology is evaluated by the extent of $NO_x$ reduction and the efficiency improvement. These improvements are able to save energy, extend the RT lifetime, and enhance productivity. The operating conditions that achieve the best performance and emission control for each RT burner are determined.

맥동연소기술을 적용한 산업용 복사관버너의 연소특성을 살펴보기 위해 실규모 (120,000 kcal/h) 산업용 복사관버너 설비를 사용하여 실험실 및 현장 테스트를 수행하였다. 제철부생가스를 사용하는 산업용 복사관버너의 3 가지 종류를 하나의 W 형 복사관이 장착된 실험설비에서 실험하였다. W 형 복사관이 다수 사용되는 대형 설비를 이용하여 장기운영 실험을 실시하였다. 맥동연소기술을 적용한 기실험설비들을 대상으로 성능향상 및 배가스조절 측면에서 다양한 실험조건으로 테스트를 진행 하였다. 맥동연소기술의 적용가능성 평가를 위해 NOx 저감 및 효율향상을 분석하였다. 맥동연소기술의 적용결과 에너지 절감, 복사관 수명 향상 및 생산성 향상 등이 얻어짐을 확인할 수 있었다. 최고의 성능 및 배가스 조절을 얻기 위한 최적의 운전조건이 각 버너별로 결정되었다.
