forbrenninger

Forbrenninger refers to the chemical processes of combustion, i.e., rapid oxidation of fuels that release heat, light and reaction products such as carbon dioxide and water. In practical terms, forbrenninger describe burning processes in engines, furnaces, fires and industrial reactors. In thermodynamics, combustion is analyzed in terms of fuel–oxidizer mixtures, ignition conditions and energy release. Forbrenninger can be complete, producing mostly carbon dioxide and water when sufficient oxygen is available, or incomplete, yielding carbon monoxide, soot and other hydrocarbons, with lower heat output and greater pollutant formation.

Common fuels include hydrocarbons, alcohols, biomass and gases, while the oxidizer is typically atmospheric oxygen. The process can occur on scales ranging from a candle flame to large power plants and aircraft engines. Key concepts include ignition temperature, flame speed, adiabatic flame temperature and heat transfer. Combustion is a major energy source but also a source of air pollutants and greenhouse gases; modern approaches aim to reduce emissions through efficient engines, catalytic systems, and alternative fuels.

Safety aspects are central: flames, explosions and flashpoints pose risks, necessitating proper storage, ventilation and fire suppression. In environmental contexts, atmospheric combustion products influence air quality and climate forcing. Etymology: the term derives from the Norwegian verb brenne (to burn), via forbrenning, the process of burning.
