Coal has the largest share of utility power generation in the United States, accounting for approximately 56% of all utilityproduced electricity ( DOE, 1998). Therefore, understanding the environmental implications of producing electricity from coal is an important component of any plan to reduce total emissions and resource consumption.

Through cables, power is transferred from the generator to a nearby transformer. Stepup transformer: While moving through wires, electricity loses part of its power; highvoltage electricity does so at a lower rate than lowvoltage energy. As a result, the voltage of the electricity is "stepped up" or "boosted" as it exits the power plant.

Coal is the single most important fuel for power generation today. Nowadays, most coal is consumed by means of "burning coal in air" and pollutants such as NO x, SO x, CO 2, etc. are inevitably formed and mixed with excessive amount of inner gases, so the pollutant emission reduction system is complicated and the cost is high. IGCC is promising because coal is gasified before ...

Steam coal, also known as thermal coal, is used in power stations to generate electricity. First coal is milled to a fine powder, which increases the surface area and allows it to burn more quickly. In pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature.

The use of coal is negatively perceived, since the use of fossil fuels in power generation and other industry sectors contributes significantly to the CO 2 emissions worldwide. Of the main fossil fuels, coal has the lowest H:C ratio, and consequently coal has the highest CO 2 footprint per unit of combustion energy produced. Coal also contains percentage levels of heteroatoms (forming NO x and ...
