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.

Method for the incinerating of sludge in which predried sludge is dried to residual moisture by the addition of heat in a first processing step and then is pyrolyzed, with the continued addition of heat and the exclusion of air, in a second processing step, and in which the pyrolysis gas obtained is used at least partially to generate the hot fumes required for heat input, characterized in that the predried sludge is carried co-currently with the hot fumes in the first processing step and that said sludge dried to residual moisture in the first step is then carried in the second processing step in countercurrent flow to said same fumes.
