Beschreibung
Zusammenfassung:	The present invention relates to a power generation system capable of generating power with high efficiency by using off-gas discarded in a process of generating industrial fuel by FT reaction of a synthetic gas generated by a coal gasification process. The power generation system of the present invention comprises: a coal gasification unit for generating a synthetic gas by supplying oxygen to pretreated coal; a pressure swing adsorption (PSA) device for supplying oxygen to the coal gasification unit; an FT reaction unit for generating industrial fuel through the FT reaction by receiving the synthetic gas from the coal gasification unit; and a power generation unit for generating electricity by receiving unused off-gas, which is not participated in the FT reaction, from the FT reaction unit to drive an engine. 본 발명은 전처리된 석탄에 산소를 공급하여 합성가스를 생성하는 석탄 가스화부; 상기 석탄 가스화부로 산소를 공급하는 압력순환 흡착장치(pressure swing adsorption, PSA); 상기 석탄 가스화부로부터 합성가스를 공급받아 FT 반응을 통해 산업용 연료를 생산하는 FT 반응부; 및 상기 FT 반응부로부터 FT 반응에 참여하지 않은 미활용된 오프가스를 공급받아 엔진을 구동시켜 전기를 발생시키는 발전부; 를 포함하여 이루어져, 석탄 가스화 공정으로 만들어지는 합성가스를 FT 반응시켜 산업용 연료를 생산하는 과정에서 버려지는 오프가스를 활용하여 고효율로 발전을 할 수 있는 발전 시스템에 관한 것이다.
