Description
(図3参照)で補正した値を、拡散燃焼から予混合燃焼等への切替時の燃空比とし、燃料流量を決定する。
Claims (2)
- ガス燃料を用いた、拡散燃焼から予混合燃焼に燃焼形態を切り替えるガスタービン設備において、ガス燃料中の不活性ガス濃度を測定し、上記不活性ガス濃度に基づき、拡散燃焼から予混合燃焼への切替時の燃空比を、安定燃焼となる燃空比の限界値に燃空比裕度を上乗せした値に補正して、ガス燃料供給流量を制御するようにしたことを特徴とするガスタービン設備の燃料供給流量制御装置。
- 請求項1に記載のガスタービン設備の燃料供給流量制御装置において、測定した不活性ガス濃度と、燃料比重および発熱量の相関関係から、上記燃料比重と発熱量の時系列的な変化を測定し、ガス燃料供給量を制御することを特徴とするガスタービン設備の燃料供給流量制御装置。
