Recent results about the compaction of coal logs and the economic feasibility for the transportation of coal by pipeline
- Univ. of Missouri, Columbia, MO (United States). Capsule Pipeline Research Center
The coal log pipeline (CLP) R and D program at the University of Missouri recently constructed a 150 mm diameter pipeline and a 2.2 MN coal log compaction machine. These two systems are being used to demonstrate the practicality of CLP by producing coal logs of commercial size. In CLP, coal is pressed into the form of cylinders that are propelled by water flowing through a pipeline installed underground. The solid-to-water ratio is 4 to 1 in a CLP and the coal log velocity is approximately 3 m/s. The transport of coal over long distances by CLP has many performance advantages including low cost and low energy consumption. The system is environmentally friendly. This report focuses on CLP results obtained in 1997 for the design and construction of the compaction press. In addition, data are presented for the total CLP system costs as a function of throughput and distance.
