See full text

A process for lowering the carbon content in ash includes introducing the ash having a carbon content of 1 to 20 wt-% into a reactor where the ash is burnt at a temperature between 700 and 1100° C. Fuel is also introduced into the reactor. During combustion, microwave radiation is fed into the reactor. At least part of the energy released during the combustion is recovered.
