förbränns

Förbränns is a Swedish verb form meaning is burned or is combusted. It is the present passive form of the verb förbränna, which describes the process of burning or combustion, typically releasing energy and transforming material through oxidation.

Grammar and usage: In Swedish, the present passive is often formed by adding the suffix -s to the active verb. Thus förbränna becomes förbränns in the present passive. The subject of förbränns is the material undergoing combustion, while the agent performing the burning can be omitted or introduced with av, as in “träet förbränns av elden” (the wood is burned by the fire). The form is common in technical, scientific, and everyday language when the emphasis is on the process rather than on who is performing it.

Contexts: The term is used in discussions of energy production, incineration, waste management, and chemical reactions. It can describe how substances react with an oxidizer under suitable conditions to produce heat, light, and various combustion products. While the passive form is frequent, Swedish also uses other constructions to convey similar meanings, such as active voice or alternative passive expressions, depending on nuance.

Examples:

- Materialet förbränns i närvaro av syre.

- Biobränslet förbränns i en panna för att generera ånga.

- Avfall förbränns i en avfallsförbränningsanläggning.
