What condition can oils and solids accumulation on the water surface in the boiler lead to?

Corrosion

Water hammer

Foaming

Oils and solids accumulation on the water surface in a boiler can lead to foaming. When these contaminants are present, they can disrupt the normal water surface tension and create a layer that does not allow steam to escape effectively. This results in bubbles forming and expanding, which can carry water droplets into the steam system. This phenomenon is known as foaming, and it can severely affect the boiler's efficiency and safety. It can result in an uncontrolled release of water into the steam lines, leading to potential damage and operational problems. The presence of such contaminants must be managed to ensure smooth boiler operation and prevent accidents.
