Now all kinds of boilers have appeared. As the name implies, gas boilers refer to gas-fired boilers. Gas boilers are the most economical compared to others, so most people choose gas boilers as boilers for steam, heating and bathing. device.
I believe that many users have heard of boiler business staff from major manufacturers when purchasing gas boilers. They should configure softened water treatment facilities for the boilers. So, what exactly does this demineralized water treatment facility do? For gas boilers, what is the necessity? Let's take a comprehensive look at this demineralized water treatment device today.
What is demineralized water?
Soft water refers to water after equipment softening and deaeration treatment. Soft water treatment can reduce the content of calcium and magnesium salts in hard water such as tap water and mineral water, so that its water quality meets the water quality standards required by boiler equipment.
Why use soft water?
Scale is known as the "source of harm" to all types of boilers. The use of soft water can prevent boiler scale and reduce the corrosion of the metal on the heated surface. Reduce boiler failure rate and extend service life.
How does scale come about?
The impurities in the boiler water are continuously concentrated during the chemical reaction during heating and evaporation. 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.
What harm does scale cause to the boiler?
a. The heating pipe is burned due to overheating and the scale has poor thermal conductivity. Too much and too thick scale of the heating pipe will cause the internal temperature of the heating pipe to not spread and cause cracks in the outer pipe of the heating pipe.
b. A large amount of energy is wasted. When the boiler is scaled, the thermal conductivity of the heating pipe is reduced, which prolongs the heating time and increases the power consumption of the equipment. The higher the boiler working pressure, the lower the scale thermal conductivity, the higher the scale thickness, and the greater the amount of wasted electricity.
c. Reduce steam pressure When scale is formed on the inner wall of the boiler or the heating pipe, the heat will not be transferred to the boiler water quickly, and the steam pressure of the boiler will be reduced, so that the output pressure of the equipment cannot meet the requirements for use.
d. Increasing the maintenance cost After the boiler wall or heating tube is scaled, it is very difficult to remove, especially the heating tube or furnace body cracked and corroded by scale, which not only damages the equipment, but also consumes a lot of manpower and material resources for maintenance , Resulting in increased maintenance costs.
e. Reduce the service life of the boiler The boiler must be cleaned with chemical agents after severe scaling. Excessive cleaning times will cause damage to the boiler, reduce the service life of the boiler, and increase hidden safety hazards.
According to the equipment requirements of gas boilers, the use of demineralized water is a benefit 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 staff will emphasize to users that it is necessary to configure the boiler softened water Device.
