Boiler descaling agent

2009-02-10View Original

Thread Content

The boiler in the factory was inspected a couple of days ago, and it was said that descaling agents are needed, and they must be used regularly. But this thing isn’t cheap either. Is it really necessary to use descaling agents regularly?

Of course, boiler water treatment chemicals are necessary; otherwise, the boiler will suffer from corrosion and scaling, which can harm its normal operation

Boiler water treatment chemicals are definitely necessary~~

Try using it? Let’s see if it works! It can generally be used.

Can anyone provide a formula for descaling agent?
Reply #62009-04-06
In fact, I don’t even know if it works or not! That’s how it’s used. Does anyone know if there are any differences in the heating furnace before and after using the descaling agent?

Descaling agents have a certain pH level, so the amount used must be controlled. A detailed plan must be developed before carrying out the descaling process. Furthermore, the formation of scale is mainly due to substandard water quality; it is crucial to ensure that the water quality is qualified or meets the standards. The amount of descaling agent used does have an impact on the lifespan of the equipment.

How about having an in-depth discussion on the use of boiler descalers? I think this is a topic related to the use of equipment, energy savings, and its lifespan; I don’t want to create a separate post, so how about discussing it in this post instead? Dear seniors, please speak up! There are many water treatment devices outside the furnace, and they are quite good, but it is also necessary to add chemicals inside the furnace.

The water treatment for boilers is primarily aimed at preventing scaling in the boilers. However, due to improper handling methods or insufficient other conditions, scale often forms to varying degrees in some boilers. To ensure the safe and economical operation of the boiler, scale must be removed promptly. Currently, the methods used for descaling include mechanical descaling, alkali boiling descaling, and acid cleaning descaling. 1. Mechanical descaling method: When there is loose scale or sediment in the boiler, shut down the boiler, allow it to cool down, drain the water from it, and then rinse it with clean water before proceeding with descaling. Mechanical descaling involves using flat shovels, wire brushes, and powered pipe grinders to remove scale. This method is relatively simple and is often used in small boilers with a simple structure. However, mechanical descaling is labor-intensive, has poor descaling efficiency, and can easily damage the boiler itself; therefore, extra care should be taken when performing this descaling process, and it should not be used excessively. 2. Alkali descaling method: The chemical formula and dosage used in the alkali descaling method are determined based on the specific conditions of the boiler. Soda ash, tannin, or alkaline descaling agents are commonly used. During alkali treatment, a non-pressurized boiler can be used, with the treatment duration being no less than 24 hours (this time can be extended slightly if there is a thick layer of scale). To improve the effectiveness of scale removal through alkali treatment, the alkaline solution can be circulated; the higher the circulation rate, the better the scale removal effect. The alkali cooking method is simple to operate and has relatively few side effects. The disadvantages are a long cooking time, high consumption of chemicals, and poor effectiveness. 3. Acid cleaning for descaling: This method mostly involves using an acid cleaning solution prepared by combining hydrochloric acid or nitric acid with an appropriate amount of corrosion inhibitor. Inject (or drive in) into the pot for descaling. The effectiveness of the pickling solution lies in its ability to dissolve, remove, and loosen scale, thereby achieving descaling. The pickling and descaling process is relatively complex and requires professionals to carry it out ; The pickling solution must be prepared based on the nature and thickness of the scale, with strict requirements ; Due to the use of acid in the pickling process, it has a certain corrosive effect on boilers; therefore, boilers should not be pickled too frequently. However, the pickling descaling method is more effective, and thus has been put into practical use. For scale that is difficult to remove with hydrochloric acid, it can also be pre-treated with an alkaline boiling method before acid cleaning.

It is necessary to remove scale, and in particular, the quality of water used in the boiler must be carefully controlled.

For boiler descaling, should acid and alkali be used to treat the boiler after it is shut down, or should they be added while the boiler is in operation?

To truly do a good job in boiler water treatment, it is not necessary to use scale removers. It turns out that many boilers functioned just as well without descalers. For some small boilers and those where water treatment is unreliable (such as those with unreliable equipment, poor water quality, or no water treatment technicians), as well as those that are used intermittently like hot water boilers, using scale inhibitors can indeed be beneficial – it helps to reduce corrosion and prevent the rapid formation of scale. However, it is important to pay attention to the quality of such products to avoid being deceived.

Adding that chemical can keep the water quality unchanged, allowing it to be used as before?

There is a new technology covered by a U.S. patent, which is the best in every regard; currently, companies such as Mobil, Zhuye, Yuncopper, China Gold Lingnan, Datang Group, Panzhihua Iron and Steel, PetroChina, and Sinopec’s subsidiaries are all using it. This technology is highly effective for dewaxing, anti-waxing, descaling, and anti-scaling of oil pipelines, boilers, and circulating water pipes.
