ABSTRACT:
A method and apparatus for fabricating coal logs from crushed coal available at a mining site and for transporting coal logs through a pipeline to a combustion site for further coal processing and burning. The pipeline is operated to maintain the hydraulic carrier fluid flowing through the pipeline within a range of bulk velocities sufficient to force a layer of the hydraulic carrier fluid between contacting surfaces of each coal log and the pipeline, tending to lift and carry the coal log through the pipeline, and, thereby, significantly reduce the energy required to transfer the carrier fluid and the coal logs through the pipeline. The carrier fluid bulk velocity is also maintained sufficiently low to prevent unstable coal log flow behavior often resulting in coal log jamming and abasion. The range of optimum fluid bulk velocities is a function of various fluid and coal properties, the pipeline geometry and the coal log geometry.
