Boiler Feed Water - Lenntec

Boiler Feed Water - Lenntec

Boiler feed water is used to produce steam. The pressure of the steam (0,5 - 100 bar) determines the temperature and energy capacity, but also the quality of the feed water. The general rule is the higher the pressure the more strict the quality of the boiler feed water.

salts is known as hard water. Where the water is hard, these are mainly calcium silicates and magnesium compounds. Under boiler operating conditions, these salts come out of solution and form scale deposits on the hot boiler metal. This is due to the decomposition of bicarbonates and to the decreased solubility of calcium salts at higher ...

Soft Water: A Must For Commercial Water Heating System

Boiler Benefits - Do you have a boiler as part of your water heater setup?If so, you have one more reason to use softened water. Sediment in a boiler can clog the heat exchanger, (the tube inside the boiler responsible for keeping the water hot) and eventually that heat exchanger will give way and spring a leak.

There are many types of boiler applications, the primary ones being hot water and steam. Hot-Water Applications. In hot-water applications, boilers typically operate within a stable closed-loop system in which the water chemistry is fairly constant. This means water is treated and stabilized for use during the initial fill of the system.

Boiler Maintenance and Boiler Service Tip

A water softener is used to remove hardness from the boiler make-up water. They are available in a wide range of sizes and configurations. By removing hardness in the water you will protect your boiler from the formation of scale that can rob your boiler of its ability to transfer heat efficiently.
