Relationship between slurry concentration and viscosity
Thread Content
What is the relationship between the concentration and viscosity of water-coal slurry? What are the minimum driving requirements?
The concentration is generally maintained between 58–63%, while the viscosity is typically kept within the range of 800–1200 cp. In general, viscosity is influenced by factors such as coal particle size, concentration, type of coal, and additives; adjusting the viscosity by increasing the amount of additives is the most common method used to raise the concentration of water-coal slurry. Furthermore, as the particle size decreases, the viscosity also increases; typically, the appropriate amount of additive is determined through experimentation in order to adjust the particle size distribution. A low concentration usually requires more energy, which is detrimental to production; we keep it at a minimum of 58%
