Coal Washing

Reducing NOx* Emissions

Removes mineral and chemical material

Reduces emissions from coal use

Use of low NOx burners to minimize the production of NOx during combustion

Selective Catalytic Reduction (SCR) technologies lower NOx emissions by treating the NOx post-combustion

SCR technology has removed between 80-90% of NOx emissions

TECHNOLOGIES FOR CHANGE

Particulates**

Underground Coal Gasification

Electrostatic precipitators (ESP) use an electrical field to attract particles to collecting plates

Fabric filters collect particulates removing over 99.95% of particulate emissions including Mercury and other heavy metals

*NOx: Nitrogen Oxides

**Particulates: finely divided solid and liquid (other than water) substances that are emitted from power stations

Coal is left in the ground and converted to gas by chemical means and then sucked up to the surface where it is burned

Eliminates most problems associated with coal mining
