1. There are conventional coal water slurries (CWS) and coal water fuels (CWF). In the CWS case, pipelines ship coal at a ratio of approximately 50:50 coal and water by weight in a turbulent flow. In addition to water, other types of fluids can be considered vehicle fluids, such as oil, liquid carbon dioxide, or methanol.Web

The common carrier for coal in pressurized oxy-coal combustion is water, and the solid-fluid mixture is called slurry. Studies reported that the coal to water ratio could be up to 75% Coal powder: and 25% Water by mass, respectively, for successful operations [26, 27]. Increasing the ratio above the recommendations presents challenges such as ...Web

For example, it is noted in [12] that the recommended value of the dynamic viscosity of coal–water fuel for spraying is 1000–1200 mPa·s at a viscometer spindle shear rate of 100 s[sup.-1]. This is a fairly high value, in comparison with the viscosity of heated fuel oil—20–50 mPa·s. As a result of high viscosity values, the diameter of ...Web
