Coal Ash Contaminates Our Lives Earthjustice
Coal Ash Is a Hazardous Waste. Coal ash, the toxic remains of coal burning in power plants, is full of chemicals that cause cancer, developmental disorders and reproductive problems. It poisons our water and kills fish and wildlife. But despite the threat, both the U.S. Environmental Protection Agency and the White House have done little to protect the waters we drink from coal ash contamination.get price
How Coal Works Union of Concerned Scientists
Pulverized coal plants can only capture CO2 after combustion, when it is far more diluted and harder to separate, increasing the costs of implementing CCS. Pre- and post-combustion technologies are both expected to capture between 85 and 95 percent of a plant's CO2.get price

Coal Use and the Environment WCA
The combustion of coal can result in trace elements being released from power stations with potentially harmful impacts to both human health and the environment. A number of technologies are used to limit the release of trace elements including coal washing, particulate control devices, fluidised bed combustion, activated carbon injection and FGDs.get price
An Introduction to Combustion (Burning) Reactions
Combustion is an exothermic reaction, so it releases heat, but sometimes the reaction proceeds so slowly that a temperature change is not noticeable. Good signs that you are dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water, and heat as products.get price
