We believe that many customers in the purchase of steam boiler, have heard a lot of boiler manufacturers talk about the need to equip boilers with softeners. For the steam boiler, what is the necessity? Today we will introduce the water softener in detail.

1.Soft water refers to water that has been softened and deoxygenated by the equipment. Soft water treatment can reduce the content of calcium and magnesium salts in tap water, mineral water and other hard water, so that the water quality can meet the requirements of boiler equipment.

2.Boiler using soft water advantages:
1) When the boiler uses the water softener, it greatly saves the waste of a lot of fuel. When the boiler boils water, there will be a thick layer of scale slowly, for the working pressure of 1.4mpa boiler will form 1 mm scale, it will waste 8% of the fuel. Not only the waste of fuel, but also the pollution of the environment.

2)Water softener can improve thermal efficiency and reduce output. When scale occurs on the evaporation surface of the boiler, the output of the boiler will be reduced because the heat from the fire side cannot be transferred quickly to the feed water side. If the water is not treated properly, when the boiler scale occurs, the boiler steam will be greatly reduced.

3)Using a water softener will reduce boiler maintenance. When a large amount of scale is produced in boiler pipes, it is difficult to remove. Scale will cause boiler leakage, deformation, corrosion and a series of hazards. It not only damages the boiler, but also consumes a lot of manpower and material resources to overhaul, not only shortens the operation time, but also increases the overhaul cost.

4)The application of water softener effectively reduces the occurrence of accidents. For such as the selection of softening water equipment, must be in line with the principle of quality, safety, in order to ensure that the water softening processing can play an effective role.

According to the equipment requirements of steam boiler, the use of water softener is one of the necessary conditions to ensure the stable operation of the boiler. Therefore, professional boiler manufacturers will emphasize to customers that water softeners should be equipped.

During the operation of the steam boilers, the water quality will be checked regularly to ensure the quality of the steam, and at the same time, the sewage will be discharged frequently. Then, why should the steam boilers discharge sewage? Xinda boiler introduces you：

Reasons for blowdown of steam boilers:

During the operation of the boiler, the boiler water with more salt and water slag is discharged to the outside of the boiler, which is called boiler blowdown.

The feed water entering the steam drum always contains a certain amount of salt. After dosing in the boiler, the fouling substances in the boiler water will be transformed into water slag. In addition, the boiler water will also produce some corrosion products when corroding metals. Therefore, there are various soluble and insoluble impurities in the water.

During the operation of the boiler, only a small part of these impurities are taken away by the steam, and most of them remain in the boiler water. With the continuous evaporation of the boiler water, the concentration of these impurities gradually increases. big. Excessive concentration of impurities in boiler water will not only affect the quality of steam, but also cause scaling and corrosion of the heating surface, affecting the safe operation of the boiler. In order to control the quality of boiler water, boiler blowdown must be carried out to discharge part of the boiler water contaminated by salt and water slag, and supplement it with clean feed water.

We have introduced the reasons and methods of blowdown of steam boilers above. When using boilers, users should always pay attention to the operating conditions of the boilers, and discharge the blowdown correctly to ensure the quality of steam and the normal operation of production.
