Generating Electricity from Coal
Duke Energy has been using coal to produce electricity in the Carolinas since 1911. Those first coalfired plants (in Greensboro,, and Greenville, ) only supplemented the company''s use of hydroelectricity. In the 1920s, the growing demand for electricity began to outstrip the availability of hydroelectric generation.

What is coal?
However, there are actually two main types of coal: ''thermal'' coal, which is mostly used for power generation, and ''metallurgical'' coal, which is mostly used for steel production. Thermal coal is more abundant, has lower carbon content and is higher in moisture than metallurgical coal.

What is Lignite?
The balance is used to generate electricity, which provides power for more than 2 million consumers and businesses in the Upper Midwest. Because of its high weight relative to its heat content, lignite is expensive to transport and is typically used in pulverized coal or cyclonefired electric production power plants close to the mine.

COAL BASED THERMAL POWER PLANTS: COAL MILLS
Boilers for steam generation in power plants and process industries use coal as fuel. The percentage of boilers operating with coal as fuel outnumbers the boilers using all other fuels combined. Coal is pulverized before firing for achieving a stable and efficient combustion. Many types of pulverizers are used in boilers by different designers.

Coal fired power plant
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coalfired power plants, according to the Energy Information Administration

Chapter 7 COAL
Of the three fossil fuels in common use – natural gas, petroleum, and coal – the United States has far more coal than gas and petroleum (compare Figures 71, 81 and 91). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal
