The Korean government views coal-fired power plants as the key cause of the fine dust generation, and is developing an energy policy to replace and demolish old coal-fired power plants. According to the Eighth Power Supply Base Plan (2017-2031), the maximum power capacity in 2030 is expected to be 100.5GW, which is 17.9% higher than the current level (85.2GW). The plan aims to reduce the facility size and power generation ratio from nuclear and coal resources to even lower levels than today, and to rapidly expand power generation from new and renewable energy. Despite that, the proportion of coal power generation is still much higher than other resources, and it is expected that the reliance on goal will maintain for next several decades. Under such circumstances, the development, supply, and expansion of clean coal technology (CCT) that is eco-friendly and highly efficient, is crucial to minimize the emission of pollutants such as carbon dioxide and fine dust, as well as maximize the energy efficiency. The Korean government designated the Yong-Dong Thermoelectric Power Plant in Gangneung to develop clean coal power generation, and executed related projects for three years. The current study aims to suggest a plan to develop parts, technologies, testing, evaluation, certification, and commercialization efforts for coal-fired power generation, In addition, the study proposes a strategy to vitalize local economy and connect the development with creation of more jobs.

Due to global economic growth, there is an increasing need for energy. Fossil fuels will continue to dominate the world energy supplies in the 21st century and coal will play a significant role. Since coal is one of the most important fossil fuels in the world, coal gasification technology appears to be an inevitable choice for power and chemicals production and has a leading place in Clean Coal Technology (CCT). The most eminent environmental advantage of coal gasification lies in its inherent reaction features that produce negligible sulfur and nitrogen oxides, as well as other pollutants in a reducing atmosphere. The gasifier was operated for a throughput of 1.0 ton & 10.0ton coal per day at pressures of 1~20Bar. Gasification was conducted in a temperature range of $1,100{\sim}1,450^{\circ}C$.

청정석탄이용기술개발의(CCT : Clean Coal Technology) 일환으로 차세대 발전방식으로 유력시되고 있는 기술인 석탄가스화발전기술(IGCC), 석탄가스화 연료전지(IGFC)등에서 고온건식탈황은 필수요소기술이다. 고온건식탈황기술의 핵심기술은 탈황제개발고 공정기술개발로 나누어 볼 수 있다. 탈황제개발은 국내고유 탈황제개발 연구가 진행 중에 있고 유동층과 고속유동층에 적합한 탈황제를 kg단위로 성형하여 공정개발에서 반응특성 실험을 하였다.(중략)

CCT(Clean Coal Technology)의 응용분야인 IGCC, PFBC 및 MCFC 등 석탄을 이용한 새로운 발전기술에 활용될 것으로 예견되는 고온건식 탈황기술은 고온(35$0^{\circ}C$~$650^{\circ}C$)과 고압(약 20기압)상태에서 금속 산화물로 된 고체흡수제(고온건식 탈황제)를 이용하여 반응기(유동층, 고속유동층 및 고정층과 이동층 반응기 등)에서 흡수와 재생반응을 통하여 석탄가스중에 있는 H$_2$S 등 황화물을 효율적으로 제거하는 기술이다.(중략)
