Description
図1には、シュラウド12およびノズル14などの例示的な高温ガス構成要素10が示されている。シュラウド12は、ガス経路表面18と対向表面19との間に配置された内部キャビティ16を含む。ガスタービン(図示せず)の動作中、高温ガスは、ガス経路表面18に沿って流れる。キャビティ16は、構成要素に冷却を行うための冷却空気源(図示せず)と流体連通する。図1にさらに示すように、インサート20は、シュラウド12に形成されたキャビティに挿入されてシュラウド12を冷却する。以下でさらに詳細に説明するように、インサートは、ガスタービンの動作中に「ホットスポット」に曝されるそのような構成要素の耐用年数を延ばすのに役立ち、費用効果の高い方法で高温ガス経路構成要素の部分に冷却を行うのを援助する。一実施形態では、そのようなインサートは、冷却を構成要素の所望の部分に行うための合理的に実現可能な唯一の方法(従来の非常に高価な方法がない場合)とすることができる。
