Coal and the Environment Energy Explained, Your Guide To

Fly ash and bottom ash, which are residues created when power plants burn coal; In the past, fly ash was released into the air through the smokestack, but laws now require that most emissions of fly ash be captured by pollution control devices. In the United States, fly ash and bottom ash are generally stored near power plants or placed in landfills.

Impact of fuel selection on the environmental performance

Traditionally, coal is used in the production of cement due to its high heating value, homogeneous composition, favourable radiative heat transfer characteristics, and relatively low costs. Although an increasing amount of cement plants has started to co-fire less carbon intensive fuels, such as waste streams and biomass to reduce CO 2 emissions, coal is still the most dominant fuel used in cement
