Please ask everyone : What is the difference between desalted water containing "ammonia" and desalted water without "ammonia"?
The most basic point is that the pH values are different. The pH value of desalted water containing ammonia is higher. There will be less corrosion on the pipes.
The pH value is different. The desalted water with ammonia added has a higher pH value. Controlling the appropriate pH value of boiler water can effectively prevent corrosion of boiler internal parts and play a role in protecting boiler internal parts. It should be noted that: Pipes and valves through which ammonia-containing solutions pass cannot be made of copper.
study* Yes, it won’t work if the pH is too high.
The main purpose of adding ammonia is to neutralize H2CO3 in desalted water and prevent corrosion of boiler components, not the difference between the two.
The difference between desalted water containing "ammonia" and desalted water without "ammonia" is that in the preparation process of desalted water, in order to protect the reverse osmosis, the reverse osmosis inlet water needs to be adjusted to a pH value of 7.0--7.2 during the water production process. A certain amount of hydrochloric acid needs to be added to adjust. The pH value of desalted water at the reverse osmosis outlet is only about 6.5. In order to ensure the alkalinity of the boiler feed water, ammonia water is used to adjust the pH value when the desalted water is sent to the boiler, and is generally adjusted to 8.8--9.2
