forbrænder

Forbrænder is a Danish noun meaning a device that burns fuel, typically translated as burner or combustor. In engineering and industry, a forbrænder is the component that introduces fuel and oxidizer, sustains combustion, and transfers heat from the flame to a process or system. It is used across domestic and industrial applications, including gas stoves, water heaters, boilers, furnaces, kilns, and gas turbines, as well as waste incineration plants.

Burner designs vary; common categories include premixed burners, where fuel and air are mixed before entering the combustion chamber, and diffusion burners, where fuel and air mix in the flame zone. Other variants aim to reduce emissions, such as low-NOx burners, or to operate at variable load.

Operation relies on stable flame, appropriate air–fuel ratio, ignition source, and safety interlocks. Modern forbrændere are equipped with sensors for flame presence, temperature, and pressure, and are integrated into burner management systems that can shut down fuel supply on fault conditions. Reliability and efficiency depend on proper maintenance, clean fuel supply, and correct installation.

In translation, forbrænder commonly corresponds to "burner" or "combustor" in English. The term is primarily used in Danish, with related terms in Norwegian and Swedish appearing in technical usage.
