Abstract
Description
本発明は、例えば、内部が冷却されたガスタービンロータブレード等の、ガスタービンコンポーネントの空洞を洗浄するための方法に関する。この種のガスタービンコンポーネントを洗浄するために、これらのコンポーネントは、洗浄プロセス前に汚染度をチェック又は決定するため、好適には、X線技術を使用して洗浄プロセス前に検査される。
Claims (12)
- ガスタービンコンポーネント、特にガスタービンブレード上の空洞を洗浄するための方法であって、この目的を達成するため、腐食性洗浄溶剤及びそれに続いてリンス溶剤が、ガスタービンコンポーネントの洗浄対象の前記ガスタービンブレード上の空洞又は各空洞を通して、特に繰り返し導かれるものであり、
まず、ガスタービンコンポーネントの前記ガスタービンブレード上の空洞又は各空洞が不活性ガスで満たされ、次いで、ガスタービンコンポーネントが好適には繰り返し熱処理を受ける一方、前記不活性ガス雰囲気が前記ガスタービンブレード上の空洞又は各空洞において維持され、この目的を達成するため、前記ガスタービンコンポーネントは、第1の時間間隔において加熱され、第2の時間間隔の間この温度に維持され、続いて、第3の時間間隔において冷却され、それに続いて、洗浄溶剤及びリンス溶剤が前記ガスタービンブレード上の空洞又は各空洞を通して導かれる、方法。 - 前記ガスタービンコンポーネントは、第1の時間間隔において、第1の処理温度から第2の処理温度へ加熱され、第2の時間間隔の間、この第2の処理温度で維持され、続いて第3の時間間隔において、第2の処理温度からほぼ第1の処理温度へ冷却される、請求項1に記載の方法。
- 前記第1の処理温度は、280°K〜320°Kであり、前記第2の処理温度は1,200°K〜1,300°Kである、請求項2に記載の方法。
- 一回の熱処理の時間、すなわち、第1、第2、及び第3の時間間隔の合計が、45〜170秒、好適には105秒である、請求項1〜3の少なくとも1項に記載の方法。
- 前記第1の時間間隔は5〜20秒、好適には15秒であり、前記第2の時間間隔は10〜60秒、好適には30秒であり、前記第3の時間間隔は30〜90秒、好適には60秒である、請求項4に記載の方法。
- 前記熱処理は、その都度前記ガスタービンブレード上の空洞又は各空洞における前記不活性ガス雰囲気を維持しながら、連続して、10回まで、好適には6回まで実行される、請求項1〜5の少なくとも1項に記載の方法。
- 前記熱処理に続き、腐食性洗浄溶剤として、水酸化物溶液が、前記ガスタービンブレード上の空洞又は各空洞を通して導かれる、請求項1〜6の少なくとも1項に記載の方法。
- 腐食性洗浄溶剤として、35%〜45%の水酸化カリウム溶液が、前記ガスタービンブレード上の空洞又は各空洞を通して導かれる、請求項7に記載の方法。
- 前記水酸化物溶液は333°K〜503°Kの温度を有し、前記ガスタービンブレード上の空洞又は各空洞を通して480〜700分の時間に18〜21バールの圧力で導かれる、請求項7又は8に記載の方法。
- 前記腐食性洗浄溶剤に続き、リンス溶剤として、脱イオン水が前記ガスタービンブレード上の空洞又は各空洞を通して導かれる、請求項1〜9の少なくとも1項に記載の方法。
- 前記洗浄溶剤に続き、リンス溶剤として、脱塩水が前記ガスタービンブレード上の空洞又は各空洞を通して導かれる、請求項1〜9の少なくとも1項に記載の方法。
- 前記リンス溶剤は278°K〜372°Kの温度を有し、前記ガスタービンブレード上の空洞又は各空洞を通して5〜30分の時間に30〜600バールの圧力で導かれる、請求項1〜11の少なくとも1項に記載の方法。
