The R and D project 'DENSECOAL Transportation Chain' provided the development of a complete technology for production, transportation in pipelines, ships and tank vehicles, as well as storage and combustion of highly concentrated coal-water slurries. The concentratability and the flowability of the slurries are determined by the coal's properties, its grain size and grain size distribution and by chemical additives. The hydraulic long-distance pipeline transport of the slurries can be calculated on the basis of laboratory experiments and extensive examinations in practical pipe sections, using computer models; technical and economical alternatives can be optimized. Transshipment and transportation by ships and/or wagons are essentially determined by the static and dynamic storage stability of the slurries. The main conditions permitting operation on the relevant sea routes have been ascertained and converted into practical operating procedures. On a small-scale plant level, highly concentrated coal-water slurries have been burned; the results show a good-quality-combustion. (orig.).
