Method and plant for thermal waste disposal

Plant for thermal waste disposal, comprising a pyrolysis reactor converting waste into carbonization gas and substantially non-volatile pyrolysis residue, a discharge device connected to said pyrolysis reactor having a non-volatile pyrolysis residue outlet and a carbonization gas discharge fitting for removal of carbonization gas, a combustion chamber operated with an oxygen excess being connected to said carbonization gas discharge fitting for receiving the carbonization gas, a residue sorting device connected to said pyrolysis residue outlet of said 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 said residue sorting device for transporting the finer coarse components, a grinding apparatus having an inlet side connected to said transport device and a discharge side for feeding the finer coarse components to said combustion chamber after grinding, said combustion chamber having means for maintaining combustion gases produced from delivered combustible material for a sufficiently long time at a sufficient temperature level to produce molten slag, said combustion chamber having an outlet for removing the molten slag, means downstream of said outlet of said combustion chamber for cooling the molten slag into a glassified form, a flue gas line leading from said combustion chamber, and a chimney connected to said flue gas line.
