Coal slurry pipeline transportation may be divided into two major types: fine coal transportation and coarse coal transportation. Fine coal implies that the solid particles have a maximum size of about 8 mesh while coarse coal imples maximum particles sizes in the range of 2-1/2 to 4 inches. Fine coal transportation is feasible only for long distances (over 50 miles). Likewise, coarse coal transportation is practical only over short distances. Because of the hydraulic characteristics of coal-water, coal-methanol, coal-fuel oil and coal-liquid CO/sub 2/ slurries, all have been considered technically feasible for fine coal slurry transportation. Because of slurry preparation and separation constraints only the coal-water system is suitable for short distances. An overview of the advantages and disadvantages of each system is given along with a comparative analysis. The results are presented in terms of a relative transport energy efficiency ratio which evaluates the fuel value delivered and the energy required to pump it. There is also a comparison of fine and coarse coal systems and current and proposed coarse coal schemes are discussed.
