coal slurry pipeline criteria Le Palais du Dragon

Slurry pipelines use a slurry of water and pulverized coal. The ratio of coal to water is about 1 to 1 by weight. Coal log pipelines use coal that has been compressed into logs with a diameter 5 to 10% less than the diameter of the pipeline and a length about twice the diameter of the pipeline. The ratio of coal to water is about 3 or 4 to 1.

Here are important criteria for designing coal-slurry

The author analyses the factors affecting the design of a coal-slurry pipeline system, considering the three types of material involved: as-mined or parent coal; as-transported coal slurry, as-fired coal-water fuel. Mathematical formulae are developed to aid engineering design, and a material balance is shown.
