초록

유동층가스화기는 경제적으로 기술적으로 입증된 기술로서 가장 상용화에 가까운 가능성을 보여주고 있다. 그러나 한국에서는 설계, 현장문제 해결뿐 아니라 파일럿 규모의 설비 운전 등이 부족하여 상용화에 이르지 못하고 있다. 본 연구에서는 바이오매스의 가스화를 위하여 3 MWth 급 순환유동층(CFB) 반응기를 개발하여 운전하였다. 유동층반응기는 순환유동층 반응기와 기포유동층 반응기로 구성되었으며 타르와 산성가스를 제거하기 위하여 세라믹필터, 급속냉각, 습식스크러버를 사용하였다. 3MWth 급 바이오매스 가스화기의 최적 운전조건을 도출하기 위하여 equivalence ratio에 따른 영향을 조사하였다

Fluidized bed gasification is technically and economically proven technology, which shows the high possibility of realization and commercialization. However, in Korea, development of FBG to the commercial scale for power generation and industry is mainly blocked by the fact that there is no experience of design, troubleshooting and operation of even pilot scale fluidized bed gasifier. In this study, a $3MW_{th}$ circulating fluidized bed(CFB) was newly developed for biomass gasification. The fluidized bed was mainly composed of circulating and bubbling fluidized reactors integrating in-situ tar removal step in the system. For cleaning of the tar and acid gas in the product gas, the sequential gas cleaning process comprised of a ceramic filter, rapid quencher and wet scrubber was adopted. Effect of equivalence ratio was investigated to find the optimal operating conditions for the $3MW_{th}$ integrated system of fluidized bed gasification.
