Are there viable technologies to eliminate the “white smoke” from power plant chimneys?
Thread Content
When the saturated, wet flue gas emitted from a power plant’s chimney comes into contact with the cooler ambient air, the water vapor contained in the flue gas becomes supersaturated and condenses as it cools down. These condensed water droplets refract and scatter light, causing the plume of smoke to appear white or gray, resulting in a thick, white smoke. Is there a technique to eliminate it?

The saturated wet flue gas emitted from power plant chimneys is a result of environmental protection measures; carbon molecular vaporization combustion is used to prevent pollution at its source, thereby reducing the amount of pollutants and eliminating saturated wet flue gas. Thus, the plume can be eliminated. file:///C:\Users\C\AppData\Local\Temp\ksohtml\wpsED2C.tmp.pngfile:///C:\Users\C\AppData\Local\Temp\ksohtml\wps89D9.tmp.pngfile:///C:\Users\C\AppData\Local\Temp\ksohtml\wpsAA73.tmp.png
These days, smokeless chimneys are popular, along with three towers and one
Find a way to conduct heat exchange at low temperatures, reducing the flue gas temperature below the dew point so that the water vapor can be condensed. But what the heck is carbon molecule vaporization combustion on the 3rd floor?
Could you provide a detailed introduction to one and two? Even the gods can’t access the link to your local drive.
“Three towers and one unit represent cost savings, but they cannot solve the problem of white smoke.
No water is sprayed; the temperature is reduced through air cooling before the exhaust gases are released into the atmosphere
The attachment is an introduction to the vaporization and combustion of carbon molecules.
Apart from water vapor, the main harmful substances in smoke plumes are sulfur dioxide and nitrogen oxides. Sulfur dioxide is a colorless gas with a strong, irritating odor, and it readily dissolves in human blood and other viscous fluids. SO2 in the atmosphere can cause respiratory tract inflammation, bronchitis, emphysema, conjunctivitis, and other conditions. It also reduces teenagers’ immunity and weakens their resistance to diseases. Under the action of oxidants and light, SO2 can produce sulfate aerosols; these sulfate aerosols can cause diseases in humans and increase mortality rates.
Thank you. In other words, the smoke plumes are eliminated, removing all the remaining sulfur dioxide and nitrogen oxides from the chimneys? 100% elimination? I must have misunderstood. Not much is known about smoke plumes. :lol
Cyclone separator to remove water molecules and silica!
It’s not about eliminating sulfur dioxide and NOx by 100%, but rather ensuring emissions meet the specified standards, or achieving ultra-low emission levels.
Thank you. I have an illusion; I always feel like something is going on at the chimney outlet. It turns out the trick was done before going into the chimney. Its purpose is to meet the requirements regarding environmental emission control, to prevent corrosion of chimneys, and to eliminate unpleasant visual effects, thereby reducing people’s concerns about smoke emissions
Although simple “white plumes” have no impact on environmental quality, they affect the perceived environment, and sometimes may even be mistaken for toxic or harmful exhaust gases. Although the tiny water droplets formed by the condensation of wet flue gas pose little harm, they can cause some inconvenience to the residents living in the vicinity, and the environmental protection agency frequently receives complaints of this kind. Therefore, many coal-fired power plants regard eliminating “white plumes” as one of the key aspects of their ultra-low emission upgrades. The main reason is people’s visual perception. It’s such a waste.
Yes, first condense to remove water and salt, then heat.
We have the technology; we’ve implemented several systems in Zhejiang. Those interested can send a private message to Engineer Xu at 13093022738
Hello! What is your technology? What are the advantages compared to other technologies?
If you have the skills, please give a brief introduction.
