Combustion processes refer to the chemical reactions that occur when a fuel reacts with an oxidant, typically oxygen, producing heat and light. This reaction can be complete, where the fuel is fully consumed, or incomplete, resulting in byproducts like carbon monoxide and soot. Common examples include burning wood in a fireplace or gasoline in a car engine. These processes are essential in various applications, including energy production, heating, and propulsion. In power plants, combustion of fossil fuels generates electricity, while in vehicles, it powers engines. Understanding combustion is crucial for improving efficiency and reducing environmental impacts.
