Abstract
Description
図1において、ガスタービン1は、圧縮機2と、複数の燃焼器3と、タービン4と、排気室5と、を圧縮空気C及び燃焼ガスGの供給・排気方向の上流側から下流側に向けてこの順に備えている。圧縮機2は、圧縮空気Cを生成する。複数の燃焼器3は、圧縮機2から供給される圧縮空気Cを一旦車室Sに貯め、さらに圧縮空気Cと燃料とを混合して作動流体である燃焼ガスGを生成する。タービン4は、燃焼器3から供給される燃焼ガスGにより回転動力を発生させる。排気室5は、タービン4を通過した燃焼ガスGを排気する。また、ガスタービン1は、軸線Oを回転中心としてタービン4の周方向Rに回転するロータ6を備えている。
