Concentration and viscosity of coal slurry
Thread Content
Water-coal slurry is a low-pollution, high-efficiency, pipeline-transmittable coal-based fluid fuel that is produced through physical processing from approximately 65% coal, 34% water, and 1% additives. It changes the traditional way of burning coal, offering significant environmental and energy-saving advantages. Especially in recent years, with the adoption of waste recycling technologies, environmentally friendly water-coal slurry has been developed, which **improves the environmental benefits of water-coal slurry without increasing costs. Backed by our country’s abundant coal resources, water-coal slurry has also become the most fundamental and economical clean energy source as a substitute for fuels such as oil and gas. On the production line, water-coal slurry is associated with two quality parameters – slurry concentration and slurry viscosity. The concentration of the water-coal slurry indicates the amount of solid components (including coal powder and additives) present in it; therefore, the slurry concentration affects a range of performance indicators of the water-coal slurry ； Viscosity, in Newtonian mechanics, is a measure of the shear force that occurs between fluids and between fluids and equipment when non-ideal fluids are in motion; it also reflects the quality of water-coal slurry. From our experience with various companies that work with water-coal slurry, they all desire to be able to detect its concentration online. Does this mean that the concentration of water-coal slurry is more important than its viscosity? We also ask the experts to give us some guidance
The concentration of the coal slurry directly determines the efficiency of gasification, which in turn has an impact on economic benefits; therefore, great attention is paid to this concentration. Moreover, there are many factors that influence it, so it can sometimes be difficult to increase its concentration； Regarding viscosity, it is sufficient to ensure the fluidity and stability of the coal slurry; this can be controlled by adjusting the additives directly, so there isn’t much discussion on this topic.

Are there any other opinions from everyone? Feel free to post, thank you.
The particle size distribution is the key parameter for high concentrations of coal slurry
Concentration, viscosity, and particle size distribution are important parameters of coal slurry. A higher concentration of coal slurry contributes to improved gasification efficiency, increases gas production, and generates greater economic benefits. The viscosity only needs to be suitable for the transport of the coal slurry, and it can be adjusted through additives. The particle size distribution affects the concentration of the coal slurry, and the concentration of the coal slurry in turn influences its viscosity; therefore, a reasonable formulation of the coal slurry requires taking these factors into account. I hope this will be helpful to you, and let’s make progress together!
