Control of medium-pressure waste boiler water during transformation
Thread Content
How does everyone control the sodium ion content in the water of medium-pressure waste boiler systems during transformation? Is the sodium ion content high in steam?
Calcium carbonate solution and calcium hydroxide are injected into the desulfurization tower; the heat from the flue gas is used to evaporate the water. Sulfur dioxide in the exhaust gases reacts chemically with the calcium-based desulfurizing agents to form gypsum, thereby achieving air purification.

Sodium ions can be controlled by the amount of chemical added (trisodium phosphate); as long as the level and pressure of the waste fluid are properly controlled, as well as the amount of chemical added, the steam will generally be of satisfactory quality.
Control the chloride content through wastewater discharge control, without adding chemicals separately
By discharging waste water, it is possible to control the sodium content, which is equivalent to the salt content. When adding sodium phosphate, it is sufficient to ensure that the phosphate level remains within the specified range; too much should not be added, as this can lead to an excess of sodium ions in the boiler water, and consequently an excess of sodium ions in the steam
