ABSTRACT:
In a procedure and an installation for the incinerating of sludge, predried sludge is dried to residual moisture by the addition of heat in a first processing step and then pyrolized by the continued addition of heat and the exclusion of air in a second processing step, with the pyrolysis gas obtained being used at least partially to generate the hot fumes required for heat input. To incinerate sludge in a way which is compatible with the environment, saves energy and is inexpensive, the predried sludge is carried co-current with the hot fumes in the first processing step and the so-dried sludge is then, in the second step, carried in countercurrent flow to those same fumes. An evaporation worm-gear machine (1) with a worm shaft (9) capable of being driven by rotation, with at least one spiral coil (14), which is placed in a housing (3) serves to carry out the first processing step, while a pyrolysis rotation cylindrical reactor (2) with an opposite direction of movement of the material which is in the hollow-built worm shaft (9) serves to effect the second processing step.
