Chapter 5 : Boiler Water - Hawkstone Solutions Inc

Unfortunately, the boiler water directly at the tube surface is much hotter than the bulk boiler water. As vapour bubbles are produced next to the tube wall, the salts capable of being liquefied stay inside the water. This creates a small area with a great amount of salts, even if the bulk boiler water may be lower than the amount of saturation.
