Q: Is the presence of non-condensable gases detrimental to condensation heat transfer?

A: During condensation heat transfer, the process primarily relies on phase change to achieve heat exchange, as the latent heat of phase change is significant, enabling substantial heat absorption or release at a constant temperature. Non-condensable gases, however, do not undergo phase change and therefore cannot absorb or release heat at the heat exchange interface. Instead, they occupy space in the gas flow and reduce the available heat transfer area, thereby decreasing heat transfer efficiency.

Q: What is dryness?

A: Dryness refers to the percentage of the mass of dry steam contained in wet steam relative to the total mass of the wet steam.

Q: What is steam calorific value?

A: Steam calorific value is not a fixed value. It generally has two parameters: one is saturated steam, whose humidity is proportional to pressure, and so is its calorific value. The other parameter is superheated value, where the calorific value of such steam is related to pressure and superheat temperature.
