How to calculate the amount of water carried away by flue gas
Thread Content
When the flue gas passes through the spray liquid, how to calculate how much water in the spray liquid the flue gas can take away, and how to judge the temperature of the flue gas when it is discharged. The previous algorithm was to assume a certain exhaust gas temperature and then how much water can be vaporized based on the drop in flue gas temperature. Now I want to find a criterion to see how low the flue gas can drop after a few seconds of reaction time? (Note: The flue gas and the spray liquid are in direct contact, so the contact area is difficult to determine and I don’t know how to calculate it). I hope some expert can give me some advice!
First, select the direct cooling structure. Calculate the cooling results based on the cooling structure and conditions. For example, direct spray cooling tower. In the calculation process, there is calculation of contact time. Most of them are based on experience. There are relevant articles and design documents on the forum for reference. Please refer to relevant papers. http://bbs.hcbbs.com/thread-81997-1-32.html This post was last edited by Albertlu on 2009-2-20 21:15 ]
The person above is right. I am considering a direct spray tower (desulfurization tower). Now I just want to write down a calculation formula for exhaust gas temperature related to contact time and contact liquid volume. I hope the expert above can give more details.
