What does "priming" refer to in relation to boilers?

Carry over water in the steam
Removing air from a system
Using numbers that can only be divided by themselves and one
Decompressing steam

The correct answer is: Carry over water in the steam

Priming in relation to boilers refers to the phenomenon where water is carried over with the steam, leading to the entrainment of water droplets into the steam system. This can pose several problems, including reduced efficiency and potential damage to downstream equipment. When steam is formed in a boiler, it is crucial that it is dry and free of water to ensure optimal performance. If priming occurs, it indicates that there is an imbalance in the boiler's operating conditions, such as excessive water levels or high levels of agitation. Managing these conditions is vital for maintaining boiler efficiency and safety. The other options do not capture the essence of priming within the context of boiler operation. Removing air from a system addresses air binding or aeration, which is distinct from water carryover. Numbers that can only be divided by themselves and one pertain to prime numbers, which is unrelated to boiler terminology. Decompressing steam involves reducing pressure within the steam system, which is a separate operational concern from the issue of priming. Understanding the significance of priming is essential for anyone involved in boiler operation and maintenance, as it impacts overall system performance and safety.
