What occurs during boiler priming?

During boiler priming, water is carried over with the steam. This phenomenon typically happens when there is too much water in the boiler or when there is excessive agitation within the boiler's water column. Priming causes small amounts of water to be entrained in the steam, leading to the production of wet steam instead of dry steam, which can negatively impact the efficiency of the system and potentially damage downstream equipment.

Options related to excessive steam production, wild water level fluctuations, or sudden temperature drops do not directly describe the primary issue of boiler priming. While these factors could be symptomatic of other conditions, they do not accurately define what occurs during the priming process itself. Proper management of boiler operation helps prevent priming, ensuring that only dry steam is produced for effective system performance.
