Claims (2)

  1. 정해진 압력에서 증기를 발생하는 일정한 저부한계치를 가지는 보일러(6)의 카스케드식 배치로 구성되는 증기발생장치(6, 12, 14, 16)와, 상기 증기발생장치(6, 12, 14, 16)로부터 증기가 공급되도록 연결된 흡기노즐을 가지는 터빈 제1단계부(4)와, 제1과열기 장치(12)와, 제어가능한 단면적을 가지는 증기 흐름통로를 표시하는 분배밸브장치(14)와, 분배밸브장치(14)와 흡기노즐사이에 연결된 제2과열장치(16)로 구성되는 증기터빈 시스템의 저부하수준 운전방법에 있어서, 상기 분배 밸브 장치(14)에 의해 표시되는 증기흐름 통로의 단면적이 감소되며, 증기 흐름통로의 단면적의 감소에 비례하는 양만큼 상기 제2과열기장치(16)의 증기로 열이공급되는 속도는 증가되는 것을 특징으로 하는 증기 터빈 시스템의 저부하수준 운전방법.
  2. 제1항에 있어서, 보일러 증기압력은 일정한 저부한계치로 유지되면서 증기흐름 통로의 면적이 감소되며 열공급 속도가 증가되는 것을 특징으로 하는 증기 터빈 시스템의 저부하수준 운전방법.
