process and power plant to lower the carbon content in ash

摘要

process and power plant to lower the carbon content in ash. The present invention relates to the reduction of the carbon content in the ash, where the ash is introduced into a reactor (3) with a carbon content of 1 to 20 wt% and is burned there at temperatures from 700 to 1100 ° C. 198 c. During combustion, microwave radiation is fed into the reactor (3) and the energy released during combustion is at least partially recovered.
