Boiler water treatment. These chemicals react with calcium and magnesium compounds in the feed water. Sodium silicate is used to react selectively with magnesium hardness. Calcium bicarbonate entering with the feed water is broken down at boiler temperatures or reacts with caustic soda to form calcium carbonate.
Boiler feedwater also contains dissolved gases, such as carbon dioxide and oxygen, that react in a boiler and lead to corrosion of the boiler internals and the piping system. If these gases are not extracted from the water supply before entering the boiler, the corrosion will eventually eat through boiler tubes and cause leaks and equipment failure.
Some feed water treatment chemicals, such as chelants, if not properly applied, can corrode feed water piping, control valves, and even the boiler internals. While the elimination of oxygen from boiler feed water is the major step in controlling boiler corrosion, corrosion can still occur. An example is the direct

Feedwater with a lower concentration of dissolved solids is then added to replace the “blown down” water. Another way in which we treat boiler feed water is by adding chemicals to the water. Our boiler chemical treatment produces a reaction that consumes many of the scale-forming minerals.
Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam. The term may also be applied to raw water intended for use in boilers, treated boiler feedwater , steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.
In low-pressure boilers, chemical cleaning typically removes calcium carbonate and other hard adherent scales. In higher-pressure boilers, the major deposit removed is magnetite and some copper. Chemical cleaning can improve the boiler heat rate and reduce the number of tube failures. It typically improves the stability of boiler chemistry.

Boiler Chemical Injection How do I inject my boiler chemical? First, determine the type of boiler you have. It is either a hot water boiler or a steam boiler. Both of these systems chemical feed is drastically different. What is a hot water boiler? A hot water boiler is a boiler that does not generate steam.
There are several different chemical approaches used to treat boilers and their selection and performance depend upon many factors. Some of these include: 1. Feedwater characteristics. 2. The type and reliability of external treatment. 3. Boiler type. 4. Boiler pressure and heat flux. 5. Steam load and variations in load. 6.
Thermal degassing (pressure degassing) of boiler feedwater requires that the water be boiling. The mixture of condensate and fresh water is fed into the degassing dome at the top. Heating up to the boiling temperature occurs with heating steam, which flows into the degassing unit at the bottom and flows upward against the current.
Chemical Treatments for Waterside of Boiler Tubes The feedwater is composed of makeup water (usually city water from outside boiler room/ process) and condensate (condensed steam returning to the boiler). The feedwater normally contains impurities, which can cause deposits and other related problems inside the boiler. Common impurities in water

water heating boiler chemical boiler feedwater WTCCI Chemicals & Equipments for Steam Boiler Water Treatment: Chemical treatment of the boiler is necessary to protect it from the Ill-effects of corrosion, deposition & fouling.
Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems. Fresh water contains dissolved oxygen. Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems. To avoid corrosion the oxygen in the make-up water for saturated steam production should be removed by using some kind of scavenger chemicals and/or deaeration towers.
