Abstract

본 발명은 실링 가스 공급 장치에 관한 것으로, 발전 시스템의 터보 머신으로 실링 가스를 공급하는 실링 가스 공급 장치에 있어서, 상기 실링 가스 공급 장치로 작동 유체를 공급하는 공급원은 적어도 하나의 저온 공급원과, 상기 저온 공급원보다 높은 온도의 작동 유체를 공급하는 적어도 하나의 고온 공급원을 포함하며, 상기 작동 유체는 상기 실링 가스 공급 장치 내에서 상기 실링 시스템에서 요구되는 온도 조건인 실링 조건에 맞게 혼합하여 터보 머신의 실링 시스템으로 공급되는 것을 특징으로 한다.
본 발명에 따르면 터빈 실링 가스 공급원을 개선하여 정상 운전 중에 별도의 전력 소모가 없어지므로, 소모 전력의 절감에 따라 발전 성능이 향상되는 효과가 있다.
