How is Coal Energy Produced?

Coal was king of energy in bygone days, but its gas emissions have been historically troubling because of the high degree of its carbon emissions byproduct. Coal is extracted from swamps and ancient forests' biological materials, which remains in a compacted state of layered biological material. Time spent in that condition builds heat, and coal is extracted from the material through mining.

From Decomposition of Biological Material to Coal

As decomposition of the materials take place over many years, oxygen and hydrogen atoms rise from the materials; however, carbon atoms remain intact and become compressed pressure layers of heat in a biological furnace. Time spent in that condition determines coal's hardness. Three types of coal are mined from the biological furnace in the forms of anthracite, bituminous and sub-bituminous coal.

How Coal Energy is Produced

Energy is locked into coal as chemical bonds formed during fossilization. Coal is released from its chemical bonds, when heat serving as a severance tool activates coal energy and releases the energy in the form of heat. 

Heat Transference

Heat energy released by coal is then transferred to water, which causes it to boil. Energy from the boiling water creates steam that is held under intense pressure, and steam then spins and powers the turbine on the generator.

The Turbine Channels Energy.

The turbine's job is to channel the energy away from the steam pressure to a spinning motion that powers an electrical generator to produce electricity.

Coal Energy Mirrors Other Sources of Energy Processes

Coal energy performs the basic steps of energy transference that other sources of energy practice and differs only by using heat transference to produce energy.
