Title
(KO) 비균질 입력 가스를 갖는 가스 터빈 발전소
Abstract
(KO)
본 발명은 환형 입구 영역을 갖는 압축기(1), 적어도 2개의 버너들, 연소 챔버(4,14,15) 및 터빈(7,16,17)을 포함하는 가스 터빈(6)의 작동 방법에 관한 것이다. 상기 방법에 따라서, 압축기의 유입 유동의 평균 산소 농도보다 낮은 산소 농도를 갖는 저산소 가스(21)로 구성되는 적어도 하나의 제 1 부분 유입 유동, 및 신선한 공기(2)로 구성되는 적어도 하나의 제 2 부분 유입 유동이 입구 영역의 원주 방향으로 교번 방식으로 상기 압축기(1)에 공급된다. 또한, 본 발명은 가스 터빈(6)을 갖는 가스 터빈 발전소에 관한 것으로서, 상기 압축기 입구(3)는 적어도 하나의 제 1 세그먼트(51) 및 원주 방향으로 상기 압축기 입구 주위에 교번 방식으로 배열되는 적어도 하나의 제 2 세그먼트(52)를 포함하고, 저산소 가스(21)를 위한 공급부는 상기 압축기 입구(3)의 적어도 하나의 제 1 세그먼트(51)에 연결되고, 신선한 공기 공급부는 상기 압축기 입구(3)의 적어도 하나의 제 2 세그먼트(52)에 연결된다.
