The level of the remaining ammonia solution is rising too rapidly
Thread Content
The amount of ammonia vapor to be treated is much greater than that of the ammonia water produced by the coke ovens; why then can’t the excess ammonia water be processed? There is suspicion that there are leaks between the tubes in the primary cooler and the secondary cooler
It’s very likely; you can check by shutting down one unit and opening it up to inspect. Also, be sure to control the moisture content of the coal being stored! ! !
We carried out maintenance last winter as well; there was too much water, and it was the primary cooler that was leaking – over 50 kilograms per minute flowed out from that container
What was said upstairs is quite clear; also, check whether there is any change in the consumption of new water.
Currently, the water pipes of domestic cross-coolers develop corrosion and perforations after 10 years of use, but by employing scientific operating methods, their service life can be extended to over 5 years.
Take a look at this: http://bbs.hcbbs.com/thread-843333-1-1.html. We just dealt with it a couple of days ago; it was a leak in the primary cooler. Also, check for any leaks in the heating steam, as well as in the final cooler. See if there is a noticeable increase in the liquid level in the waste liquid tank – conduct a thorough inspection
Check whether there is any loss of circulating water and whether the consumption of fresh water has increased； Additionally, checking whether the liquid discharge volumes from the primary cooler and the final cooling tower have increased can also help determine if there is any leakage
