Abstract
A cement clinker prodn. plant has a raw material pretreatment stage (1), a clinker firing kiln (2), an off-gas line (3) connecting the kiln to the pretreatment stage, a clinker cooler (4) and, connected to the off-gas line (3), a reactor which produces a fuel gas from waste materials (esp. old tyres) and which is in the form of a gasifying reactor (5) connected to the cooler via a tertiary air line (6) such that at least part of the waste air from the cooler (4) can be used as gasifying medium in the reactor. The provision of a device (8) for controlling the tertiary air amount supplied by the tertiary air line to the reactor in accordance with the waste material filling height and/or the temp. in the reactor. Also claimed is a corresponding cement clinker prodn. process.
