- 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。 - 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。
- 前記物質がNOxである、請求項7記載の方法。
- 前記排気(16)の温度が、800〜900°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。
- 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つの排気通路内で前記周囲空気(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。
