为了减少不可逆损失，设计时应使其为干饱和蒸汽。

In order to reduce the irreversible losses, it must be saturated steam at the throat of diffuser.

分析表明，传热不可逆损失是火用损失的主要部分，占40%。

Further, the exergy analysis reveals that the irreversibility of heat transfer (40 percent) is the major source of exergy destruction.

在燃烧过程可用能分析的基础上，提出可用能损失率指标，它可用于衡量燃烧过程不可逆损失的程度。

Based on exergy analysis of combustion process, the exergy loss rate was presented to estimate the irreversible exergy loss.
