Abstract
【解決手段】希釈オリフィス(67)が、移行部片(55)の壁(64)内に形成されている。希釈オリフィス(67)は燃焼流路(72)に希釈ガスを案内する。熱遮蔽部材(80)が、燃焼流路(72)における移行部片(55)の壁(64)に取り付けられている。熱遮蔽部材(80)は、第1の表面(136)および対向する第2の表面(137)を有するボディ(135)と、ボディ(135)を通って延びる希釈通路(140〜142)とを備える。希釈通路(140〜142)は、希釈オリフィス(67)からずれている。熱遮蔽部材(80)は、移行部片(55)の壁(64)から離間に配置されて、壁(64)と第2の表面との間に流れ領域(100)を画定している。
