Abstract

Coal gasification is considered as one of the best alternatives among clean coal technology and new concept next generation technologies are under being developed to achieve low cost as well as high efficiency. In this study we have developed double swirl multi-burner as part of the development of low cost compact gasifier. We installed new concept multi-burner with pulverized coal distributor to the body of existing gasifier for burner test. Gasification test was performed under the condition of $6.4{\sim}7.2kg/cm^2$ and $1170{\sim}1300^{\circ}C$ by using Indonesian ABK (sub-bituminous) coal to get operation condition of new concept multi-burner. Our interest was focused to ensure a stable operating condition rather than the gasifier performance evaluation. As a result, we were able to achieve the carbon conversion of 84% and the cold gas efficiency of 52.1% at the stable operating conditions.

석탄가스화 기술은 청정석탄에너지 기술 중에서 아주 중요한 대안으로 인식되고 있으며, 이에 전 세계적으로 차세대 석탄가스화기라고 할 수 있는 고효율 저비용 석탄가스화기를 개발하고 있다. 본 연구에서도 이러한 목적의 달성을 위하여 저비용으로 구현이 가능한 컴팩트 석탄가스화기를 개발하고 있으며, 다수개의 공급부로 이루어진 일체형 이중선회형 버너를 개발하였다. 개발된 버너의 가스화 운전조건을 확보하기 위하여 미분탄 분배기와 함께 기존의 석탄가스화기 몸체에 설치하여 가스화 실험을 수행하였다. 인도네시아산 아역청탄인 ABK 탄을 사용하여 1.5톤/일의 파일럿 규모로 $6.4{\sim}7.2kg/cm^2$, $1170{\sim}1300^{\circ}C$ 조건에서 운전을 수행하였다. 우선 성능평가보다는 안정적인 가스화기 운전조건을 확보하는데 중점을 두었다. 그 결과, 안정적인 운전조건에서 탄소전환율은 84.0%, 냉가스 효율 52.1%를 확보할 수 있었다.
