Expert systems and coal quality in power generation
necessary in most countries to plan to generate power from several different sources, of which coal can be a major contributor. Coal quality (that is the properties of coal) has an impact on many parts of a power plant including the coal handling facilities, pulverising mills, boiler, air heater, ESP, ash disposal as well as stack emissions.

Generating Energy from Coal
Duke Energy has used coal to produce energy in the Carolinas since 1911. The first coal-fired plants in Greensboro, N.C., and Greenville, S.C., originally only supplemented the company's use of hydroelectricity. This changed in the 1920s when energy demand exceeded what the hydroelectric stations could generate.

How is coal formed?
In time, material that had been plants became coal. Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite. These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal. Coal is defined as a readily combustible rock containing more than 50% by weight of carbon.

Coal formation
Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or coal-bearing Period.

What is a Coal Preparation Plant? (with pictures)
A coal preparation plant takes coal from a mine and cleans it for transport. When coal comes out of a mine, it is full of impurities. These impurities lower its overall value, reduce its usefulness and increase the cost to ship it. Since impure coal is so detrimental to its use, most coal mining companies own or use a coal preparation plant.
