Description
かつ、高温燃焼ガスが、第1のタービンを通過し、続いて、燃料が案内されるSEV燃焼器1として知られている第2の燃焼器に供給される。酸化ガスが、渦生成器又は生成器2を通ってSEV燃焼器1に案内される。本発明による燃料ランスは、燃焼器に燃料を案内するために備えられている。燃料ランス7は、燃料を酸化ガスとより良く混合するために設計されている。本発明の燃料ランス7は、燃料が燃焼フロントパネル5の上流の燃焼器の壁4に到達するのを妨げ、自動点火を回避するように、形成されもしている。点線6は、酸化ガスのみの領域と下流の燃料と酸化ガスの混合領域の間の境界をもう一度示している。
例えば、ランス7に対して、燃料又は酸化ガスに円周状又は接線の構成要素を与えるために、ランス7の外側表面9の周りに十分に存在するらせん状の形状が備えることが可能である。
