Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.

Condenser. Condenser is a device which condenses the exhausted steam from the turbine. The condenser serves two important functions −. It creates a very low pressure at the exhaust of the turbine, hence permitting expansion of steam in the turbine to a very low pressure. This helps in converting the steam energy into the mechanical energy.

Merchants built factories that needed water power that had to be built near water. People learned they could burn coal to make hot water for steam power. In 1769, James Watt built a good steam engine. The steam engines were being used to run machines in factories instead of water power. Now factories could be built farther away from water sources.

Some underground mines are 1,000 feet deep. To remove coal in these underground mines, miners ride elevators down deep mine shafts where they run machines that dig out the coal. Processing the Coal Source: After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining ...

Coal is primarily used as fuel to generate electric power in the United States. In coalfired 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 highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...

Since coal can heat much larger volumes of water much faster than wood, coaldriven steam engines can be much larger than wood steam engines. Coal beats wood. Oil beats coal. Dense with energy, oil provides 18,300 BTU/lb. And rather than needing to be shoveled or tossed, it can be pumped through pipes.

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.
