Abstract

Syngas was produced out of pellet refuse derived fuel (RDF) produced from an RDF production facility of W city, Korea. A two-stage gasification system was developed to use the RDF char as an auxiliary heat source for gasification reaction. The composition and heating value of syngas as well as the heating value of residual product (char) were measured at a different residence time to investigate the optimal operating condition of the two-stage gasification system for syngas production. The optimal char residence time to minimize the energy cost due to an external heat source supply was also deduced.

본 연구에서는 W시에서 운영하는 RDF 생산시설의 펠렛 RDF를 이용하여 RDF의 가스화 반응으로 합성가스를 생산하였다. 생산된 RDF 촤를 소각로에 투입하여 연소과정에서 발생되는 열을 가스화로의 간접열원으로 이용하는 2단 가스화시스템 공정을 개발하였다. RDF의 가스화 반응 시간에 따른 합성가스 발생 비율과 잔재물(촤)의 발열량 분석 등을 통하여 2단 가스화시스템 공정에서의 합성가스 생산 최적 운전조건을 연구하였다. 가스화로의 외부 열원 공급에 필요한 에너지 비용 저감을 위해 최적의 촤 체류시간을 도출하였다.
