Combustion phenomena refer to the chemical reactions that occur when a fuel reacts with an oxidant, typically oxygen, producing heat and light. This process is essential in various applications, including engines, heating systems, and power generation. The main types of combustion are complete combustion, which produces carbon dioxide and water, and incomplete combustion, which can generate carbon monoxide and soot. The efficiency and characteristics of combustion depend on factors such as fuel type, temperature, and pressure. Understanding these phenomena is crucial for improving energy efficiency and reducing harmful emissions in industrial and residential settings.
