Oct 05, 2010· Coal boilers also use small amounts of water for boiler blowdown. In this process, water is bled from the boiler to get rid of impurities that accumulate and form sludge that can impair a plant''s performance. A more efficient coal technology, called integrated gasification combinedcycle (IGCC), is being commercialized.
Natural gas, petroleum and coal continue to dominate energy consumption. Fossil fuels—petroleum, natural gas, and coal—have accounted for at least 80% of energy consumption in the United States for well over a century.
Coal is plentiful in the United States and inexpensive for its energy content. But its use comes at a cost to the environment. Learn the pros and cons of this energy source from the National Academies, advisers to the nation on science, engineering, and medicine.

Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include production of conventional, alternative and renewable sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to ...
Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration
Despite legitimate concerns about air pollution and greenhouse gas emissions, coal use is likely to continue to be significant in the future in the absence of concerted government policy. For coal to have a place as a cleaner energy source in the decades to come, greater efforts are needed by government and industry to develop and deploy less ...
