산화제 공급 각도 변경에 따른 미분탄 분사 패턴 가시화 연구

The visualization of pulverized coal injection pattern

To achieve the required higher efficiency and lower emission performance, Korea's 300 MW IGCC RDD&D (Research Development, Demonstration and Dissemination) project was launched in December 2006 under the leadership of the Korea Electric Power Corporation (KEPCO), with the support of the Korea Ministry of Knowledge Economy. Our research group, KEPCO Research Institute had set-up the a coal gasifier for the pilot test and conducted many experiments for parametric study in this project. Our group focused visualization of pulverized coal injection pattern in the gasifier. Through this study we found that two types of coal burners having different oxygen supply angles can be a source changing gasification condition like temperature.
