Coal Mill Used At Coal Fired Power Plant

In contrast, China's coal-fired power plants emitted an estimated 200 ± 90 tons of mercury in 1999, which was about 38% of Chinese human-generated mercury emissions (45% being emitted from non-ferrous metals smelting). Mercury in emissions from power plants can be reduced by the use of activated carbon.

A possible mode of operation that was tested in a coal-fired power plant and that might meet the new requirements is the so-called one-mill operation. Due to their solid design, in particular, older plants are well suited for this approach. They are often designed with an optimal reserve potential.
