PLANT FOR THERMAL WASTE DISPOSAL AND PROCESS FOR OPERATING SUCH A PLANT

摘要

The plant possesses a pyrolysis reactor (8) which is provided with a first heating device (20) for the indirect heating of the waste (A) and a second heating device (22, 22a) for the direct heating of the waste (A) within the pyrolysis reactor (8). The pyrolysis reactor (8) converts the waste (A) into low-temperature carbonization gas (s) and solid pyrolysis residue (r). These two substances (s, r), possibly after passing through a treatment device (34), are fed to a hightemperature reactor (32) for combustion. According to the invention it is now provided that the first heating device (20) ensures the basal heating of the waste (A) in the pyrolysis reactor (8). A separate fuel (b) or the waste heat from the flue gas (R) of the high-temperature reactor (32) can serve for this purpose. The supplementary heating in accordance with requirements is provided with the aid of the second heating device (22, 22a) by air feed into the interior of the pyrolysis reactor (8).
