ABSTRACT:
A plant for thermal waste disposal includes a pyrolysis reactor having a first heating device for indirectly heating the waste and a second heating device for directly heating the waste within the pyrolysis reactor. The pyrolysis reactor converts the waste into low-temperature carbonization gas and solid pyrolysis residue. The low-temperature carbonization gas and the solid pyrolysis residue, possibly after passing through a treatment device, are fed to a high-temperature reactor for combustion. The first heating device ensures a basal heating of the waste in the pyrolysis reactor. A separate fuel or waste heat from the flue gas of the high-temperature reactor can serve the purpose of ensuring the basal heating. Supplementary heating is provided as required with the aid of the second heating device by providing an air feed into the interior of the pyrolysis reactor. A process is also provided for operating the plant for thermal waste disposal.
