Pollution Control in Coal Power Plants | Hose Master

Pollution Control. Thermal Power Plants produce electricity by first creating heat, and the U.S.A. still produces most of our energy by burning fossil fuels (coal, natural gas, or oil) to create this heat. Despite our nation's move towards clean, renewable energy production, coal-fired plants still produce about 30% of our electricity.


Analysis of limestone for flue gas desulfurization in a ...

During the combustion process the sulfur in the coal combines with oxygen in the air to form SO 2. To remove the SO 2, the flue exhaust gases from a coal-fired power plant are commonly led through a spray of limestone slurry in a so-called scrubber. The resultant reaction typically captures 90% or more of the SO 2. Approximately 80-85%
