The steam exiting the medium-pressure steam drum contains high levels of sodium ions and silica
Thread Content
Recently, the sodium ion level in the drum steam is high, and the silica content is also high (not significantly above the specified limits). What is causing this? How can this situation be adjusted?
Is it because the row spacing is too small, or is it blocked?
1. Compared to before, the gas output has not seen a significant increase. 2. It is caused by continuous blowdown and the drum liquid level; check the amount of continuous blowdown and the drum liquid level.
By controlling the dosage of trisodium phosphate and ensuring proper continuous discharge, there should be no problems.
Is the liquid level deviating from the normal value, causing the discharge location to be outside the optimal position?
Are there any newly commissioned pipelines, and have samples of the condensed water collected for analysis to verify their quality?
Did you use glass bottles for sampling?
