Abstract

It is studied the effect of crystal structure of domestic High-Ca limestones using absorbent for desulfurization on the grinding characteristics and dissolution rates in wet flue gas desulfurization process of domestic coal fired power plant. It compared the crystal structure, grinding work index and dissolution rates with 4 Limestones from Jecheon-Danyang with different crystal structure, and we found that grinding work index differ in crystal size and crystal structure of limestones : The lower the value of the grinding work index is, the higher the dissolution rates of limestones. Confirmed that we have important indicators of grinding characteristics for crystal structure with CaO content of limestones.

국내 석탄화력발전소의 습식배연탈황공정에서 탈황용 흡수제로 사용하는 국내산 고품위석회석의 결정구조가 분쇄특성 및 용해특성에 미치는 영향을 연구하였다. 광물학적 결정구조가 다른 제천-단양 지역 석회석 4종을 대상으로 결정구조, 분쇄일지수 및 용해도를 비교한 결과 석회석의 결정크기와 구조에 따라 분쇄일지수 차이가 발생하였으며 분쇄일지수가 상대적으로 낮은 석회석의 용해도가 높은 것으로 나타났다. 이에 따라 석회석의 CaO 함량과 함께 결정구조에 따른 분쇄특성도 중요한 반응인자로 확인되었다.
