摘要

The major objective of this research effort was to evaluate the feasibility of producing a stable Coal/Oil/Water Slurry (COWS) emulsion utilizing cavitating emulsification technology. In order to meet this objective, the research program concentrated on the following areas of investigation: (1) The operational parameters of velocity, pressure, orifice size, intensity of cavitation, water droplet size, and percentage water added in order to produce a stable COWS emulsion were determined. (2) The experiments necessary to establish the emulsification parameters with respect to system power requirements were performed. (3) The research effort was limited to a 30 percent by weight coal emulsion. In addition to the original areas of concentration, the particle size distribution of the coal within the emulsion was also evaluated. While evaluating the distribution, an attempt was made to establish the size reduction of the coal particle as a result of exposure to the cavitating slurry. The data generated from the test results for evaluating these parameters can be used as design criteria or a prototype COWS emulsifier. COWS emulsions of 10 and 20 percent water were evaluated for particle size reduction. (ERA citation 05:024023)
