Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United

Coal has many other uses. It is used as a source of heat for manufacturing processes. For example, bricks and cement are produced in kilns heated by the combustion of a jet of powdered coal. Coal is also used as a power source for factories. There it is used to heat steam, and the steam is used to drive mechanical devices.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

1. Introduction. Clay brick is a product of a brick dough, which consists of clayey soil and water. It is formed primitively, naturally dried, and fired in the kilns in the workshop (Gür et al., 2012).Clay brick is the oldest and most used building material, has been manufactured at the waterfronts where suitable soil could be found (Ward-Perkins, 1981, Fernandes et al., 2010).

Coal mining in the United States is an industry in transition. Production in 2019 was down 40% from the peak production of 1,171.8 million short tons (1,063 million metric tons) in 2008.Employment of 43,000 coal miners is down from a peak of 883,000 in 1923. Generation of electricity is the largest user of coal, being used to produce 50% of electric power in 2005 and 27% in 2018.
