Coal pipeline
Coal pipelines are
There are two types of coal pipelines, slurry and log. Slurry pipelines use a slurry of water and pulverized coal.[1][2] 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.[3][4] The ratio of coal to water is about 3 or 4 to 1.
Coal needs a very low moisture content before it can be burned efficiently, so the
Large coal power plants use large amounts of coal each day; enough to fill a hundred train coal cars carrying 100 tonnes (98 long tons; 110 short tons) each.[citation needed] Water used to transport the coal is likewise significant, particularly in arid regions like the Southwestern United States. Such a power plant would use about 2.4 million US gallons per day (0.11 m3/s) with a coal slurry pipeline or about 700,000 US gallons per day (2,600 m3/d) with a coal log pipeline. This amounts to about 2,700 or 780 acre-feet (3,330,000 or 960,000 m3) per year respectively. The 1,580-megawatt (2,120,000 hp)
