What does "foaming" refer to in boiler operations?

"Foaming" in boiler operations refers specifically to the formation of bubbles in the boiler water, which can impede the effective production of steam. This occurs when impurities and contaminants within the water surface create a layer of foam that prevents proper heat transfer and can lead to water carryover into the steam system. This carryover can cause problems like water hammer, damage to steam traps, or contamination of steam lines and processes.

Understanding foaming is crucial for maintaining efficient boiler function and ensuring safe, reliable operation. It often indicates issues such as high levels of dissolved solids or organics in the water, making monitoring water quality a pivotal part of boiler operation management.
