Abstract

The development for processing technologies of low rank coal (brown & subbituminous coal), which has disadvantages such as non-agglomerating property, low calorific value according to high inherent moisture content, susceptibility to spontaneous combustion, was required to diversify bituminous coal import markets in Korea, importing more than 98.5 % of coal. In the present article, the development direction of domestic processing technologies for low rank coal was suggested by summarizing the reserves of low rank coal and by categorizing the utilizing technologies of low rank coal to liquid (CTL) technology, coal gasification technology, integrated gasification combined cycle (IGCC) technology, and mine mouth power plant (MMPP).

Utilizing technologies

석탄의 98.5 %를 수입에 의존하고 있는 우리나라는 유연탄 중심의 석탄사용을 다변화하기 위해 점결성이 없고, 수분함량이 높아 발열량이 낮으며, 자연발화되기 쉬워 활용이 어려운 저등급 석탄(갈탄 및 아역청탄)의 활용기술 개발이 필수적이다. 이 글에서는 저등급탄의 부존현황을 정리하고 활용기술로 액화기술, 가스화기술, 가스화복합발전기술, MMPP(Mine Mouth Power Plant)기술로 대별하고 분석･제시하여 국내외에서 자주개발 중인 저등급 석탄의 활용기술 활성화에 도움이 되고자 하였다.
