What is the term for unevaporated boiler water carried out of the steam drum with the steam?

• A. Surging
• B. Sludge
• C. Priming
• D. Foaming

Answer: (C)

The correct term for unevaporated boiler water carried out of the steam drum with the steam is priming. Priming occurs when the steam drum's water level is too high, causing liquid water to be entrained in the steam as it exits the boiler. This can lead to water droplets entering the steam system, which can cause operational issues in downstream equipment, such as turbines and heat exchangers. This phenomenon is generally undesirable in boiler operations as it can lead to efficiency losses or damage to machinery. Understanding priming is crucial for machinists so they can manage steam generation effectively and maintain the integrity of the steam system. The other terms relate to different processes or conditions in boiler operation but do not specifically refer to the carryover of liquid water with steam.
