2011-7-27 · existing or planned coal-fired power plants in Illinois. To accomplish these objectives we undertook a detailed study to delineate and characterize high-calcium limestone zones from a representative selection of quarries in the state, focusing on those within 50-miles of existing and potential coal-fired power plants.
Limestone Makes for Cleaner Coal. C&E Concrete saw a window of opportunity in the 1980''s to join the greener power generation. With the help from wheel loaders and articulated haulers they are able to contribute to the greener power movement by extracting limestone that is used by coal power plants to scrub exhaust emissions and for dust ...
2019-1-31 · , 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% of worldwide FGD units installed in power plants use wet limestone scrubbing vs. other technologies. What happens to the SO 2
