Combustion is a chemical reaction in which a fuel reacts with oxygen to release energy in the form of heat and light. This process is also known as burning.
During the combustion process, the bonds between the atoms in the fuel molecules are broken, releasing energy. This energy is then used to heat water and produce steam, which in turn drives turbines to generate electricity.
The most commonly used elements for combustion are carbon, hydrogen, and sulfur. These elements are found in fuels such as coal, oil, natural gas, and wood.
The combustion of fossil fuels releases large amounts of carbon dioxide, a greenhouse gas that contributes to climate change. It also produces pollutants such as nitrogen oxides and sulfur dioxide, which can cause air pollution and harm human health.
Combustion efficiency can be improved by using more advanced technologies such as catalytic converters and fuel cells. Additionally, using cleaner and more sustainable fuels such as biofuels can also increase the efficiency of combustion processes.
