What Is Coal Energy
Coal energy is the use of coal in energy production
How Does the energy Gained From Burning Coal Work? Energy Transfer! 1) Starts off as chemical energy
|
2) Transfers To thermal Energy (H2O(l) → H2O(g))
The combustion of carbon changes the chemical energy that is stored in the bonds of carbon to thermal energy by breaking the bonds releasing Carbon dioxide, water and heat. The thermal energy or heat energy that is acquired from the combustion of coal leads to the evaporation of water. Heat is added to break apart the hydrogen bonds between oxygen and hydrogen to produce water vapor in an endothermic reaction. 4) Transfers to electric energy The kinetic energy of these turbines generates an electric current which is sent to different parts of the city. As such, we harness the energy of coal from different processes that start with converting chemical energy to thermal energy and finally to electrical energy which is used by us in our daily lives. From watching T.V. to warming up our houses, coal plays a very important role in our lives.

A Summary of How Coal Energy Works |
- First the coal is mined, taken to a power plant and burned for thermal energy.
- The burned coal in the boiler causes the water in the pipes to become steam.
- The steam travels through a high pressure tube called a steam line and to the turbine.
- The steam then pushes and spins the turbine and then produces electrical energy.
- The spinning blades turn a shaft connected to the generator.
- In the generator, big magnets spin close to coils of wire. When this happens, electrical current is produced in the wires.
- Then the electricity goes out through wires to homes, schools, and businesses.
