Formation of Coal (Process) Coal is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, moisture, and incombustible mineral matter (, ash). Fluorinated gases are not formed by coal combustion. Coals are formed from the accumulation of vegetable debris in specialized environments. Obtaining coal from the mines is a difficult job.

Natural gas is a fossil fuel energy source. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH 4 ). Natural gas also contains smaller amounts of natural gas liquids (NGLs, which are also hydrocarbon gas liquids ), and nonhydrocarbon gases ...

The Cons of Coal Energy. 1. The mining of coal destroys natural habitats. To remove coal from the ground, various mining processes are used that destroy the natural habitat in that region. Part of that destruction involves the potential pollution of groundwater tables and the removal of trees. There is also the added danger of having a fire ...

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...
