The buildup of sludge can disable the low-water trips. The boiler water side should be inspected on a regular basis. Should any signs of scaling or build up of solids on the tubes be noted adjustments to the water treatment should be made. The water side of the deaerator should be
Chelants are the prime additives in a solubilizing boiler water treatment program. Chelants have the ability to complex many cations (hardness and heavy metals under boiler water conditions). They accomplish this by locking metals into a soluble organic ring structure. The chelated cations do not deposit in the boiler.
They are common in industries such as power plants chemical processing food and beverage processing industry heating engineering building materials. Water is the most common fluid used in heating processes due to its availability and high heat capacity. These uses require large amounts of water and often present potential for water saving.
