Boiler water issues
Thread Content
The pH value of the water in the pot is 14.2, and the conductivity of the steam is 11.2. What actions should be taken?
Increase continuous blowdown and activate periodic blowdown
1. Measure the pH of the water; if it is above 8.5, address the water treatment issue. 2. The pH value of the feed water is not high; discharge it periodically or continuously.
The pH value of the boiler water is generally kept between 9 and 11; yours is too high. Have you added too much chemical? The pH value can be reduced through appropriate boiler water replacement!
I want to ask this question too. Is there an answer?
The pH value is too high, the conductivity is not high; too much caustic soda was added.
Is this your first time heating the furnace, or have you already entered regular production? If it’s the first time, are you using trisodium phosphate or sodium hydroxide? Have you used too much of it? Additionally, you need to increase waste discharge by turning on the regular drainage system for extensive flushing; that should resolve the issue.
With such a high PH value, it’s likely that too much chemical was added! Recheck the water supply volume and chemical dosage, and make adjustments! Additionally, increase the amount of waste discharged for replacement, and conduct more water sample analyses!
