What occurrence is characterized by small particles of boiler water being carried into steam lines?

The occurrence characterized by small particles of boiler water being carried into steam lines is known as carryover. This phenomenon is critical in understanding boiler operation because it can lead to various operational issues, such as reduced efficiency and potential damage to steam lines and downstream equipment.

Carryover happens when water with a high concentration of dissolved solids or impurities is entrained in the steam as it is produced in the boiler. This often occurs due to improper water treatment or operational conditions, such as high steam production rates or excess carryover caused by foaming in the boiler. When carryover occurs, the small particles or water droplets can adversely affect the quality of steam, leading to potential failures in steam-powered systems and processes.

Understanding carryover is vital for boiler operators, as it emphasizes the importance of maintaining proper water chemistry and monitoring for signs of excessive foaming to prevent operational issues. Monitoring the conditions that lead to carryover helps maintain efficient and safe boiler operation.
