environmental pollution by coal pulveriser

Coal and Air Pollution Union of Concerned Scientists

Jul 28, 2008  Coal and Air Pollution. Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other severe environmental and public health impacts. Coal has long been a reliable source of US energy, but it comes with tremendous costs because it is incredibly dirty.

GEORGIA POWER’S PLANT BOWEN Environmental

Air were installed in the mid 1990’s. This pollution control reduced annual NOx emissions by 27%. •SO 2 emissions were reduced 40% by switching to low sulfur coal in the mid 1990’s. •Because cooling towers are used in a closed-loop cooling system, no thermal pollution from Plant Bowen reaches the Etowah River or nearby streams.

The pulverizers which grind the coal > 70 per cent less than 200 mesh (75 microns) hi PF boilers are posing maintenance problems in grinding mills due to high silica in Indian coals containing high per centage of the harder a-quartz component. These problems are virtually eliminated in FBC boilers because the coal is crushed to 12-6 mm x 0 size.
