Abstract
Description
更に、燃焼室の下流域の燃焼反応が進んだ領域に、追い焚きバーナを設けることにより、負荷変動への対応を実現できる。
したがって、ガスタービンエンジンの燃料として、例えば水素を含む反応性の高い燃料を使用する場合にも、NOxの発生を抑制しながら、極めて安定した燃焼が維持される。
また、各分岐燃料供給管66から供給される燃料Fが燃料流通路73内をほぼ均等に流れ、対流冷却の効果を十分に発揮できるように、燃料Fが燃料流通路73から燃料噴射孔39に導かれる途中に第2区画壁87を設けてもよい。つまり、環状の燃料流通路73は、外周側区画壁87aと内周側区画壁87bとによって、3つの環状の空間に分割されていてもよい。
