What is the term used when small particles of water exit the boiler with steam?

The term used when small particles of water exit the boiler with steam is "Carryover." This phenomenon occurs when water droplets are entrained in the steam as it leaves the boiler. Carryover can happen due to various reasons such as turbulent conditions within the boiler, excessive water levels, or improper boiler design. This results in water being transported along with steam, which can lead to inefficiencies and potentially damage downstream equipment if not properly managed.

The other terms refer to different processes related to water and steam but do not accurately describe the situation where water particles are carried with steam. Condensation is the process of steam cooling and turning back into water, evaporation refers to the transformation of liquid into vapor without boiling, and flash steam is a vapor that forms from water when it is suddenly released from a pressurized state to a lower pressure. Understanding carryover is essential for boiler operation and maintenance to ensure efficient and safe functioning.
