Process and plant for lowering the residual carbon content of ash

This invention relates to lowering the carbon content in ash, wherein the ash is introduced into a reactor with a carbon content of 1 to 20 wt-% and is burnt there at temperatures of 700 to 1 100°C. During the combustion, microwave radiation is fed into the reactor and the energy released during the...

Beschreibung
Zusammenfassung:	This invention relates to lowering the carbon content in ash, wherein the ash is introduced into a reactor with a carbon content of 1 to 20 wt-% and is burnt there at temperatures of 700 to 1 100°C. During the combustion, microwave radiation is fed into the reactor and the energy released during the combustion is at least partly recovered.
