Dispersions of coal in water useful as a fuel
A dispersion of coal in water comprising particulate coal dispersed in an aqueous solution with a multi-component additive, the dispersion comprising from about 60 to about 80 percent by weight coal, the multi-component additive is described comprising: (a) a water-soluble, nonionic wetting agent, the water soluble, nonionic wetting agent being selected from the group consisting of reaction products of alkyl radical substituted phenol and an epoxide, the alkyl radical having from about 8 to about 12 carbon atoms and the epoxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures thereof, the reaction products having an HLB of from about 10 to about 19, (b) a water-soluble, low molecular weight polymer, and (c) a water-soluble, medium-to-high molecular weight polymer, the water-soluble medium-to-high molecular weight polymer, the water-soluble medium-to-high molecular weight polymer being selected from a group consisting of ethoxylated cellulose, propoxylated cellulose, polyacrylic acid, starch, xantham, gum, guar gum, polyvinyl alcohol and mixtures thereof.
