Water carried over with steam is called:

The term used to describe water that is carried over with steam is referred to as priming. Priming occurs when steam bubbles rise through the water in a boiler, bringing water droplets along with them instead of allowing the steam to be free of liquid. This phenomenon indicates that the steam is not entirely dry, which can lead to inefficiencies and potential damage to steam systems.

Priming is particularly concerning in boiler operations because it can affect the performance of turbines and other equipment that rely on high-quality steam. The presence of water can cause erosion, corrosion, and other issues in the steam system. Understanding this concept is crucial for operating engineers, as they must ensure that steam is as dry as possible for safe and efficient operations.

Other terms like surging, foaming, and flashing refer to different phenomena or conditions relating to liquids and gases but do not specifically characterize the unwanted transport of water with steam in this context.
