Briefly introduce the purpose and basic common sense of boiler for water treatment
Water treatment for low nitrogen burner is one of the important links to ensure the safety and economic operation of boilers. Due to the high burning temperature of oil, the gas is high. And most fuel, gas boilers (especially imported fuel gas boilers) are small, compact, and high demand, if water treatment is not good, will cause boiler knots. Salt, corrosion, not only waste of fuel, but also causing accidents such as plugging, explosive tubes, will also cause the most economic losses of boilers. Therefore, the boiler of fuel and the gas must carefully do a good job in boiler water treatment. Basic knowledge of boiler water 1. Natural water often has a large amount of impurities in natural water in natural water, and there is often a large amount of impurities in natural water in natural water, of which there is an impact on boiler: suspended substances, colloidal substances and solubility substances. The suspension and cavity substance consists of mud, animal and plant body and some low molecular aggregate, etc., which is a major factor in turbid water. If these impurities will enter the ion exchanger to exchange resins, affect the quality of water {, if they go directly into the boiler, it is easy to deteriorate the quality of the steam, and is easily deposited into mud, block the pipe, so that the metal is damaged due to overheating. Suspension and colloidal substances can be removed through the pre-treatment method. The dissolved substance mainly refers to the salts and certain gases dissolved in water. Natural water, even if it looks very purely clear tap water, there are various dissolved salts, of which calcium magnesium salts. Typical substances are the main roots of boiler fouling. Since dim sum is extremely harmful to the boiler, remove hardness, prevent fouling is the primary task of boiler water treatment, and can be achieved by chemical treatment or dosing in the pot.

JPG Impact on fuel gas boiler equipment is mainly oxygen and carbon dioxide, they will produce oxyuritis and acidic corrosion on boilers, while oxygen and hydrogen ions are still a large effect. The depertrotic agent will accelerate electrochemical corrosion, one of the important factors of the boiler produces corrosion. Dissolved oxygen can be removed by an oxygenator or a reducing agent or the like. For carbon dioxide, the effect can be eliminated as long as the pot water has a certain pH and an alkalinity. In addition, some areas in the water source are high. After the fuel low nitrogen burners are concentrated, the pot aqueous alkalin will become higher and higher. After a certain concentration, they will be bluff on the evaporation surface, affecting the quality of steam; Under certain conditions, the alkali can also cause alkaline corrosion such as caustic embrittlement in stress concentrated parts. Therefore, a refundine treatment is required for water quality having a high alkalin. In addition, the dissolved solid content is too high, and the vapor quality is also affected, and even if it is severely caused to zone. It should be controlled by reasonable sewage. In short, the purpose of the boiler water treatment is to remove harmful impurities, prevent boiler fouling and corrosion, maintain good steam quality, and ensure the safe and economic operation of boiler.
