湿饱和蒸汽

注入油层的湿饱和蒸汽向油层顶部超覆推进以及沿高渗透区域指进一直是蒸汽吞吐开采过程中的主要矛盾。

Injected wet saturated steam moving override on top reservoir and fingering along high permeability zone have been the main problem of cyclic steam stimulation .

蒸汽过热器的作用是将锅炉汽筒出来的湿饱和蒸汽加热成为具有一定过热温度的过热蒸汽，以满足动力装置对蒸汽参数的要求。

Steam super heater can be used to heat wet saturated steam which comes from drum to a certain temperature of superheated steam to satisfy the application of power plant .

以上建立的湿空气饱和水蒸汽曲线计算模型，不仅具有快速方便的物性计算功能，还提供了准确判定湿空气状态变化的准则。

The calculation model established above could not only calculate moist air properties quickly and accurately , but also provide a formulation discriminating state change processes of moist air .
