I believe that many users have heard of the boiler business personnel of major manufacturers when buying gas boilers. They should configure the boiler with softened water treatment facilities. So what exactly does this softened water treatment facility do? Must the gas boiler be equipped with a softened water device? Today, FANGKUAI Boiler will tell you what is the softening water treatment.
1. What is softened water?
Soft water refers to water that has been softened and deoxygenated by equipment. Soft water treatment can reduce the content of calcium and magnesium salts in hard water such as tap water and mineral water, so that the water quality meets the water quality standards stipulated by boiler equipment.
2. Why should soft water be used in gas boilers?
Scale is known as the “source of all kinds of harm” for all types of boilers. The use of soft water prevents the boiler from producing scale and reduces corrosion on the heated surface metal. Reduce boiler failure rate and extend service life.
3. How is scale generated?
The impurities in the water in the boiler are concentrated and concentrated during the boiling boiling evaporation process. When these impurities reach saturation in the pot water, solid matter is precipitated. The precipitated solid object, if suspended in the pot water, is called water slag; if it is firmly attached to the inner wall of the furnace, it is called scale.
4. What are the hazards of scale to the boiler?
a. The heating tube is burned due to overheating. The scale is poor in thermal conductivity. Too much scale in the heating tube is too thick, which may cause the internal temperature of the heating tube to not spread, resulting in cracking of the outer tube of the heating tube.
b. A large amount of energy waste When the boiler is fouled, the thermal conductivity of the heating tube is lowered, thereby prolonging the heating time, resulting in an increase in the amount of electricity used by the equipment. The higher the working pressure of the boiler, the lower the thermal conductivity of the scale, the higher the scale thickness, and the greater the amount of electricity wasted.
c. Reduce steam pressure When there is scale on the inner wall of the boiler or the heating pipe, the heat will not be transferred to the boiler water very quickly, which will reduce the steam pressure of the boiler, so that the output pressure of the equipment can not meet the requirements of use.
d. Increasing the maintenance cost After the inner wall of the boiler or the heating pipe is covered with scale, it is very difficult to remove, especially the damage of the heating pipe or the furnace body caused by scale, corrosion, etc., which not only damages the equipment, but also requires a lot of manpower and material resources to repair. , resulting in an increase in maintenance costs.
e. Reduce the service life of the boiler After the boiler is seriously fouled, it needs to be cleaned with chemical agents. If the cleaning times are too many, it will cause damage to the boiler, reduce the service life of the boiler and increase the safety hazard.
According to the equipment requirements of gas boilers, the use of softened water is a profitable thing in the long run, and it is also one of the necessary conditions to ensure the stable operation of the boiler. Therefore, professional boiler business personnel will emphasize to the user that the boiler softened water treatment should be arranged.
