Coal power stations disrupt rainfall: global study
Ultrafine particles from exhaust gas filters 'worse than road traffic'
Flinders University
Modern coal-fired power stations produce more ultrafine dust particles than road traffic and can even modify and redistribute rainfall patterns, a new 15-year international study shows.
The study indicates filtration systems on modern coal-fired power stations are the biggest source of ultrafine particles and can have considerable impacts on climate in several ways.
In the Bulletin of the American Meteorological Society, the researchers report how coal-fired power stations clearly emit large amounts of ultrafine particles (UFP) through filtering technology of exhaust gas. The key findings of the long-term study are:

In the Bulletin of the American Meteorological Society, the researchers report how coal-fired power stations clearly emit large amounts of ultrafine particles (UFP) through filtering technology of exhaust gas. The key findings of the long-term study are:
- Modern coal-fired power stations emit more UFP than urban road traffic
- UFP can harm human health
- UFP can affect rainfall distribution on local to regional scales by increasing the condensation nuclei count
- UFP can be transported in layers with high concentrations for hundreds of kilometres and then lead to localised "particle events" (dramatic spikes in short-term particle concentrations on the ground) far away from their source.

(4,249 posts)1. Ah yes, the vaunted "Clean Coal" technology.
These UFPs must only be a minor annoyance, because "Clean Coal" is so wonderful.

However, I don't believe these plants qualify as what is typically termed "clean coal."
