Coal utilization - Coal combustion | Britanni
Coal-water slurry fuel (CWSF) normally consists of 50–70 percent pulverized or micronized coal, 29–49 percent water, and less than 1 percent chemicals to disperse the coal particles in the water and prevent settling of the coal. The slurry is finely sprayed (atomized) into a combustion chamber in a manner similar to that used for fuel oil.

Coal-water slurry fuel - Wikiped
A coal-water slurry fuel is defined by a number of factors including its viscosity, particle size, rate of sedimentation, ignition temperature (800–850 °C [1,470–1,560 °F]), combustion temperature (950–1,150 °C [1,740–2,100 °F]), ash content and calorific value (3700–4700 kcal/kg).. When coal-water slurry fuel combusts, over ninety-nine percent of its carbon content is consumed
