Water quality parameters of the drum

How much trisodium phosphate should be added daily to the drum water standard? Why must the water in the drum be kept slightly alkaline? Who has the parameters for drum water?
The amount of chemical to be added is determined based on the volume of deoxygenated water fed into the system, the pH value of the boiler water, and the results of regular tests on the boiler water. Generally, the pH value of water should be kept between 8.8 and 9.3
The amount of trisodium phosphate added is adjusted according to the pH value; it varies depending on the local water quality, and in some cases, the addition of trisodium phosphate can affect the chloride ions in the boiler water. The weak alkalinity of the drum water prevents acidic corrosion.
Indeed, if the water in the drum is acidic, it will corrode the equipment; therefore, it needs to be alkaline.
