Claims (10)

  1. それに沿って排気(16)を導きかつ周囲環境に放出する少なくとも1つの排気通路と、
    前記排気(16)から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(24)と、
    前記少なくとも1つの排気処理装置(24)の上流で前記少なくとも1つの排気通路に配置された1以上の周囲空気入口(28)と
    を含むターボ機械であって、前記少なくとも1つの排気通路が、その内部の前記排気(16)の圧力を低下させて前記1以上の周囲空気入口(28)から該少なくとも1つの排気通路内に周囲空気(30)をファンを用いずに引き込むように構成され、前記周囲空気(30)が、前記排気(16)の温度を低下させて前記少なくとも1つの排気処理装置(24)の有効性を高める、ターボ機械(10)。
  2. 前記少なくとも1つの排気処理装置(24)が、少なくとも1つの選択触媒リアクタである、請求項1記載のターボ機械(10)。
  3. 前記少なくとも1つの選択触媒リアクタが、前記排気(16)からNOxを除去する、請求項2記載のターボ機械(10)。
  4. 前記少なくとも1つの排気通路が、排気ポート(18)の下流に配置された混合ダクト(22)を含んでいて、前記混合ダクト(22)が、前記排気ポート(18)よりも大きい断面積を有していてその内部の前記排気(16)の圧力を低下させる、請求項1記載のターボ機械(10)。
  5. 前記少なくとも1つの排気通路内に強制的に引き込まれた前記周囲空気(30)が、前記排気(16)の温度を00〜900°F(427〜482℃)まで低下させることができる、請求項1記載のターボ機械(10)。
  6. ターボ機械(10)排気(16)を周囲環境に放出する方法であって、
    少なくとも1つの排気通路に沿って前記排気(16)を加速するステップと、
    前記少なくとも1つの排気通路内で前記排気(16)の圧力を低下させるステップと、
    前記排気(16)の圧力を低下させるステップによってファンを用いずに1以上の周囲空気入口(28)から前記少なくとも1つの排気通路内に周囲空気(30)を引き込み、それによって該排気(16)の温度を低下させるステップと、
    前記排気(16)を前記周囲環境に放免するステップと
    を含む方法。
  7. 少なくとも1つの排気処理装置(24)を通して前記排気(16)を流すステップと、前記少なくとも1つの排気処理装置(24)によって前記排気(16)から物質を除去するステップとを含む、請求項6記載の方法。
  8. 前記物質がNOxである、請求項7記載の方法。
  9. 前記排気(16)の温度が、00〜900°F(427〜482℃)まで低下し、それによって前記少なくとも1つの排気処理装置(24)の有効性を高める、請求項7記載の方法。
  10. 前記排気(16)の温度を低下させるステップが、前記少なくとも1つの排気通路内前記周囲空気(30)を該排気(16)と混合することによって達成される、請求項6記載の方法。
