Slurry pipelines. Coal slurry is a mixture of crushed coal and a liquid such as water or oil. The traditional mixture, first patented in England in 1891, consists of 50 percent coal and 50 percent water by weight. So-called heavy coal slurries or slurry fuels consist of 65 to 75 percent coal, with the remainder being water, methanol, or oil.Web
