Coal Slurry: an Idea that Came and Went WyoHistory

Nov 14, 2014  During the coal boom of the 1970s, slurry pipelines were proposed as an alternative to rail transport. Coal would be crushed, then mixed with water to create a slurry and sent via pipeline to its destination, where the mixture was dried, then burned. When in the pipeline, the slurry moved along at a leisurely four miles an hour.

Abstract. Properties of coal-water slurries were studied in two separate phases: a rheological phase and a pipeline phase. The primary purpose was to investigate the rheology of fine coal slurries, and the secondary purpose was to determine whether the energy requirements of a coal-water slurry pipeline could be predicted from the rheology data.
