Putting the coal slurry pipelines to the test

Journal Article:

Abstract

This paper deals with the advantages and disadvantages of coal slurry pipelines and describes coal slurry tests undertaken in three test circuits with 100, 200 and 250 mm diameter pipes. The test results from the test circuits were used to scale-up pressure gradients to larger pipe diameters. The construction and installation of hydraulic transport pipelines is simple and requires a minimum of space. The crossing of rivers, roads, railways or any other obstacles is comparatively easy. The operation, supervision and maintenance of a pipeline is simple since any pipeline can be easily adapted for fully automatic control. For this reason manpower requirements are small resulting in only small increases in operating costs during the life of a pipeline. This is an attractive feature in any economy troubled by inflationary trends. In transporting a commodity such as coal the quantities handled are usually large and the distances are long. The profitability of hydraulic transportation systems benefits from such operating conditions. Even though the various components of a slurry transport system, such as the slurrying facilities at the mine end and the dewatering facilities at the utilization end, are complex, their reliability is high. Against the advantages, the following limitations can be  More>>

Against the advantages, the following limitations can be visualized: It is practically impossible to transport solids other than those for which the pipeline was designed; in this regard, road and rail transportation is more versatile. The solids throughput through a pipeline cannot be economically increased beyond its design throughput. Pipelining involves the use of fluids, in most cases water, which in some instances may not be readily available.}
