The main factors affecting the viscosity of coal slurry are: ( ) A: Moisture B: Ash content C: Fixed carbon D: Particle size distribution D
A. Slurry particle size distribution: When the average particle size of the slurry is small, its viscosity increases; whereas when the particle size distribution is coarser, the viscosity of the slurry decreases. B. Slurry concentration: As the slurry concentration increases, its viscosity also increases. As the slurry concentration decreases, its viscosity also decreases. C. Amount of additive: Within a certain range, an increase in the amount of additive reduces the viscosity of the coal slurry, while a decrease in its amount increases the viscosity.
