Coal water mixture development. Quarterly technical progress report

Technical Report · Fri Jul 12 04:00:00 EDT 1985

OSTI ID:5463644

The 2000 hour equipment testing phase of the Plant Equipment Selection and Performance Project was completed early June. The final 918 hours of testing were accomplished as 13 separate runs during this quarterly performance period. The testing included runs utilizing both the progressive cavity and the twin screw pumps in burner service. The CWM utilized in the performance of these runs was from a 65,000 gallon production initially generated in August 1984. It is significant that the flow properties of this CWM remained essentially constant for almost one year in long term storage at the Vendor's facility, in transport from the east to the west coast, and in short term storage at TRW. However, it is not known whether the slurry will remain unchanged when utilized for the radio assay corrosion/erosion test scheduled for July and August. The data reported reveals the effect of differences in pumps on the stability properties of the CWM being circulated. Slurry from the first shipment was utilized to test the performance of the test loop equipment using the progressive cavity burner pump. No change in viscosity after 100 hours of circulation was apparent. Slurry from the second shipment was utilized in testing involving the twin screw burner pump, and viscosity increase of over 500% in <70 hours was evidenced. Slurry fom the third delivery was utilized in testing with both pumps and the previous effects were confirmed. The plans for the next quarter include the installation of a radio assay corrosion/erosion monitoring device to generate data for determining materials loss due to CWM service in pipe elbows and tees. An additional testing period of 200 hours is planned. 1 tab.
