ABSTRACT:
A plant for thermal waste disposal includes a pyrolysis reactor converting waste into carbonization gas and substantially non-volatile pyrolysis residue and a discharge device connected to the pyrolysis reactor. A combustion chamber operated with an oxygen excess is connected to a carbonization gas discharge fitting of the discharge device for receiving the carbonization gas. A residue sorting device is connected to the pyrolysis residue outlet of the discharge device for sorting out coarser coarse components substantially including non-combustible ingredients such as rocks, glass shards, broken porcelain, and metal parts, from combustible finer coarse components. A transport device connected to the residue sorting device transports the finer coarse components. A grinding apparatus has an inlet side connected to the transport device and a discharge side for feeding the finer coarse components to the combustion chamber after grinding. The combustion chamber maintains combustion gases produced from delivered combustible material for a sufficiently long time at a sufficient temperature level to produce molten slag. The combustion chamber has an outlet for removing the molten slag which is cooled into a glassified form downstream of the outlet of the combustion chamber. A flue gas line leads from the combustion chamber to a chimney.
