Abstract
【解決手段】内壁1aの冷却孔2aに樹脂4を詰めて遮熱コーティングを施した尾筒1の外壁1bに、シリコーン樹脂7を塗布する。そして、樹脂4を燃焼や分解して取り除くために大気炉で尾筒1を加熱する。すると、シリコーン樹脂7の一部は分解したり蒸発したりするが、一部は外壁1bに残留して外壁1bを保護する。そして、このようにシリコーン樹脂7によって外壁1bを保護することで、外壁1bの酸化や酸化による色ムラが低減される。したがって、尾筒1における灰化処理後に尾筒1の外観を良好なものにするために要する時間を大幅に短縮することができる。尚、本発明の熱処理方法は尾筒1における灰化処理だけに限らず、熱処理を必要とする製品全般に適用することができる。
【選択図】図4
Description
まず、燃焼器11について図1を用いて説明する。図1は、ガスタービン10の燃焼器11の近傍を模式的に示した断面図である。図1に示すように、ガスタービン10の燃焼器11の周囲には燃焼器11の外枠である車室10aが備えられる。また燃焼器11は、内部で圧縮空気と燃料とを燃焼させて燃焼ガスを発生させる内筒11aと、内筒11aの外側に備えられるとともに車室10aに固定される外筒11bと、内筒11aの軸位置に設けられるパイロットノズル11cと、パイロットノズル11cの外周に複数配置されるメインノズル11dと、内筒11aに接続するとともに燃焼ガスを後述するタービン13に送る尾筒1と、を備える。また、ガスタービン10は、圧縮空気を車室10a内に供給する圧縮機12と、燃焼器11で発生した燃焼ガスが供給されることによって動力が発生するタービン13と、を備える。
以上のように、尾筒1は内部を高温高圧の燃焼ガスが通過するため、耐熱及び耐食性の良いニッケル基合金などから成り、さらに壁部に冷却構造を備えている。以下に、尾筒の壁部に備えられた冷却構造について図1に加えて図2を用いて説明する。図2は、尾筒の壁部を模式的に示した斜視図であり、壁部の内部の構成を示すために一部を切り取って示している。
また、尾筒1の内壁1aには遮熱コーティングが施される。この遮熱コーティングについて、以下に図3(a)〜(e)を用いて説明する。図3(a)〜(e)は、それぞれ尾筒の模式的な断面図であり、尾筒の壁部に備えられた冷却溝と略平行な方向の断面を示している。また、図3(a)は遮熱コーティングを施す前の尾筒を示している。
以下に第1実施形態における熱処理方法について、尾筒における灰化処理を例に挙げるとともに図4を用いて説明する。図4(a)、(b)は尾筒の模式的な断面図を示しており、遮熱コーティングが施される尾筒について示した図3に相当するものである。
次に、第2実施形態における熱処理方法について、第1実施形態と同様に尾筒における灰化処理を例に挙げるとともに図5を用いて説明する。図5は、本実施形態における熱処理方法の一例を示した模式図である。
