How much carbon dioxide is produced when different fuels ...

The amount of CO2 produced when a fuel is burned is a function of the carbon content of the fuel. The heat content, or the amount of energy produced when a fuel is burned, is mainly determined by the carbon (C) and hydrogen (H) content of the fuel.Heat is produced when C and H combine with oxygen (O) during combustion.

Bituminous Coal Characteristics and Applications

Bituminous coal combustion releases more pollution into the air than sub-bituminous coal combustion, but due to its greater heat content, less of the fuel is required to produce electricity. As such, bituminous and sub-bituminous coals produce approximately the same amount of pollution per kilowatt of …

COAL -- A Fossil Fuel - Lehigh University

coal produced in the United States is subbituminous. Wyoming is the leading source of subbituminous coal. Bituminous coal contains 45-86 percent carbon, and has two to three times the heating value of lignite. Bituminous coal was formed under high heat and pressure. Bituminous coal in the United States is between 100 to 300 million years old.

Coal ash is the solid byproduct left over after coal is burned. It is second only to trash as the largest source of waste material in the US. According to the EPA and the American Coal Ash Association, coal power plants created just under 130 million tons of ash in 2014. This means that every ton of coal we burn leaves 122 pounds of coal ash.
