TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The coal particles comprise 60-70 wt.% of the slurry and the water comprises 30-40 wt.% of the slurry. The slurry further comprises at least one surfactant system comprising a nonionic surfactant, an ionic surfactant, an inorganic salt and/or organic salt. The surfactant system is present in the slurry of 500-3000 parts per million. The slurry further comprises large coal particles having a size of 150-400 mu m. The size ratio of the large coal particles to the coal particles is greater than 100. The coal particles comprise 58-62 wt.% of the slurry and the coal particles and the large coal particles comprise 68-72 wt.% of the slurry. The mass fraction of the large particle size coal is 25-35% of the total coal in the slurry. The coal particles are lignite, sub-bituminous, bituminous or anthracite. The slurry comprises large coal particles having a size of 150-400 microns suspended in a colloidal fraction of a nano-dispersion of coal in water, where the nano-dispersion of coal in water has nano-sized coal particles and micronized coal particles, where the slurry comprises water (28-32 wt.%) and the micronized coal particles (30-50%) have a size of 4 microns or less, at least 20% of the nano-sized coal particles have a size less than 1 micron with a mode size of 200-300 nm, the nano-sized and microsized coal particles comprising 58-62 wt.% of the slurry and the large coal particles comprising 10-14 wt.% of the slurry. At least a portion of the water is replaced with a volatile component, where the volatile component comprises methanol, ethanol, propanol, butanol and/or glycerol. The large coal particles are suspended in a relevant colloidal fraction of the coal particles. The slurry has a viscosity of 350-1000 centipoise at 120 degrees F. The coal particles have a size of less than 100 microns. The particle size distribution of the coal particles is: multi-modal, with a first mean particle size of 200-350 nm, a second mean particle size of 1-2 microns, and a third mean particle size of greater than 4 microns; or bimodal. The coal-water slurry further comprises: a nano-dispersion of an organic liquid or oil; and at least one alternative fuel source comprising a biomass and/or its petroleum coke, where the 50-80 wt.% of the slurry comprised of coal particles is 50-60% coal particles and 40-50% alternative fuel source. Preferred Method: The method further comprises providing the surfactant system and mixing the surfactant system with the source of water before the source of coal is provided to the chamber. The provided coal is in a pulverized form. The method further comprises controlling a formation temperature of the slurry to minimize the amount of water evaporation.
