Feed water for boilers goes through a stage of special preparation and meets certain requirements. Water treatment is important from the point of view of ensuring economical, safe and uninterrupted operation of the system.
Specialists BOOSTER RUS, which supplies and maintains steam and hot water boilers in Russia, is ready to provide professional advice on the preparation of boiler water.
Substances dissolved in water that harm the boiler
Ordinary water contains:
- inorganic substances: silicon dioxide, iron, calcium, magnesium, etc.;
- organic components: microorganisms, foreign bodies, contaminating small particles.
These are especially harmful to boiler equipment:
- iron,
- silicon,
- chloride,
- dissolved oxygen,
- calcium,
- magnesium.
Hardness components and their negative impact
These are dissolved substances that, when entering the boiler, crystallize when the temperature reaches 100℃ and above, thereby worsening heat transfer and reducing the rate of steam formation. This entails problems with excessive fuel consumption and environmental pollution, as well as a reduction in the life of the boiler.
Causes of scale formation and related problems
The principle of scale formation is that hardness components (calcium (Ca), magnesium (Mg)) and silica components dissolved in water combine with salts and then crystallize and stick to the heating surface of the boiler.
Scaling problems:Scaling problems:
- boiler water pH too low;
- foaming water;
- boiler scale deposits;
- too much oxygen in the water ;
- gases dissolved in water (oxygen and carbon dioxide);
- corrosion of the boiler;
- reduction of heat transfer and equipment efficiency;
- too high costs for water treatment.
To eliminate these problems, it is necessary to use chemicals designed for water treatment.
The main advantages of chemical treatment:
- Stabilize and disperse calcium carbonate ("lime") and iron oxides to minimize scale, deposits and corrosion.
- Foam prevention to prevent foam carryover.
- Removal of oxygen from water and providing sufficient alkalinity to prevent boiler corrosion.
- Alkalinization of boiler water and steam to protect the boiler, condensate and steam lines from significant corrosion.
It should be understood that the quality and the composition of boiler water can vary greatly, so it is necessary to adhere to the concept of water treatment, depending on the needs of a particular industrial facility. It is necessary to collect data about the system, analyze the current water parameters.
