Abstract
【解決手段】ターボ機械10は、それに沿って排気16を導きかつ放出する少なくとも1つの排気通路18と、排気16から規制物質を除去することができる少なくとも1つの排気処理装置22とを含む。複数のヒートパイプ24が、少なくとも1つの排気処理装置22の上流で少なくとも部分的に排気通路18内に配置される。複数のヒートパイプ24は、排気16から該複数のヒートパイプ24に熱エネルギーを伝達させ、従って該排気16の温度を低下させて少なくとも1つの排気処理装置22の有効性を高めることができる。ターボ機械10排気16を放出する方法は、少なくとも1つの排気通路18に沿ってターボ機械10排気16を強制的に流すステップと、複数のヒートパイプ24を通過させて排気16を流すステップとを含む。熱エネルギーが、排気16から複数のヒートパイプ24に伝達され、従って該排気16の温度を低下させる。
