Beschreibung
Zusammenfassung:	The present invention relates to a power generation system which comprises: a coal gasification unit for generating syngas using coal; an FT reaction unit receiving syngas from the coal gasification unit to produce industrial fuel through an FT reaction; and a power generation unit including a first power generation unit generating electricity by driving a mixed engine using a compression ignition method by receiving syngas from the coal gasification unit and a second power generation unit generating electricity by driving an electric power engine using a flame ignition method by receiving unused off-gas not participating in the FT reaction from the FT reaction unit. According to the present invention, it is possible to highly efficiently generate electricity by using off-gas that is wasted during industrial fuel production via the gasification of coal and the FT reaction. 본 발명은 석탄을 이용해 합성가스를 생성하는 석탄 가스화부; 상기 석탄 가스화부로부터 합성가스를 공급받아 FT 반응을 통해 산업용 연료를 생산하는 FT 반응부; 및 상기 석탄 가스화부로부터 합성가스를 공급받아 압축착화 방식을 이용한 혼소엔진을 구동시켜 전기를 발생시키는 제1발전유닛 및 상기 FT 반응부로부터 FT 반응에 참여하지 않은 미활용된 오프가스를 공급받아 불꽃점화 방식을 이용한 전소엔진을 구동시켜 전기를 발생시키는 제2발전유닛을 포함하는 발전부; 를 포함하여 이루어져, 석탄의 가스화 및 FT 반응으로 산업용 연료를 생산하는 과정에서 버려지는 오프가스를 활용하여 고효율로 발전을 할 수 있는 발전 시스템에 관한 것이다.
