Here are important criteria for designing coal-slurry pipelines. Full Record; Other Related Research; Abstract. 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 ...

Coal pipeline - Wikipedia

Coal pipelines are pipelines used to transport coal from where it is mined to where it is consumed. For very short distances, large trucks are used to transport coal, but trains and barges are preferred for long distances. In some cases it is more economical to move the coal by pipeline than by train or barge. This can happen when there is no suitable railway or waterway to transport the coal, or when it must be moved very long distances.

PREDICTION OF COAL SLURRY PIPELINE TRANSPORTATION

of solid while coal slurry is conveyed in a pipeline (Henderson.,1983.,Shook et al., 1978). However, the solution of the grinding model and the selection of relevant parameters needs further study. It is obvious that the working process of a ball mill or a rod mill is different from the pipeline transportation. In this study, the slurry pipeline transportation process is regarded as a special ...

The 108-mile Ohio pipeline, built in 1957 in response to high railroad rates, was deacti-vated in 1963 when the advent of the unit train made coal transportation by rail more eco-nomical than by pipeline. In 1957 the railroad rate increased from $2.63 to $3.47 per ton; by 1963, the rate had been reduced to $1.88 per ton. GOVERNOR'S ...

Coal Slurry: an Idea that Came and Went WyoHistory.org

2014-11-14  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.

Centrifugal pumps are widely used to transport slurry, usually over relatively short distances, but sometimes in long pipelines which run for hundreds of kilometres. Slurry transport is common within the mining industry as part of minerals processing or coal washing. The solids can include anything from raw or final product to fine tailings.

Coal pipeline - Wikipedia

There are two types of coal pipelines, slurry and log. 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 ...

Coal slurry - Wikipedia

Coal slurry can be transferred by pipeline or with specialized pumps such as a progressive cavity pump to pump the highly abrasive, corrosive and viscous coal slurry. More than 7 billion tons of coal are mined per year (2010), using approximately 200 litres of water per ton. However, the amount of water required hinges on the surface characteristics of the coal being used. Most coal slurries ...
