Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...

Coalfired power plants are the largest source of anthropogenic carbon dioxide (CO2) emissions into the atmosphere, with more than billion tonnes of CO2 emitted annually. In order to mitigate the emissions of CO2 from coalfired plants, several measures were proposed, such as increasing the efficiency of the plants, cofiring biomass with coal, and capturing and storing CO2 deep underground.

1. Introduction. With the massive increase in coal production, the fly ash from coalfired power plants has become the world's largest solid waste pollutant (Li et al., 2014).The longterm accumulation of fly ash will cause leakage of heavy metal elements (Stant, 2010).For China in 2015, the annual output of fly ash from coalfired power plants exceeded 580 million tons (Yao et al., 2015).
