Conceptual design of coal-fueled diesel system for stationary power applications

Description: A preliminary conceptual design of a coal-fueled diesel system was prepared as part of a previous systems study. Since then, our team has accumulated extensive results from testing coal-water slurry on the 13-inch bore JS engine (400 rpm) in 1987 and 1988. These results provided new insights into preferred design concepts for engine components. One objective, therefore, was to revise the preliminary design to incorporate these preferred design concepts. In addition there were certain areas wher… more

Development and evaluation of highly-loaded coal slurries. Phase I summary report, October 15, 1977-December 31, 1978

Description: Slurry fuels comprised of either bituminous, subbituminous, or lignite coal, and either aqeuous media or emulsions of No. 6 oil in water as the carrier were developed and evaluated at solids loadings up to 70% by weight. Emphasis was placed on aqueous slurries of bituminous coal. These slurries were developed for use in place of No. 6 oil in oil-fired burners. High solids loadings were attained by use of bimodal particle size distributions, which are blends of coarse-grind coal (approx. 50 to 8… more

Rheological properties essential for the atomization of coal water slurries (CWS). Quarterly progress report, September 15, 1993--December 15, 1993

Description: The overall objective of this project is to perform experiments to understand the effect of high shear and extensional properties on the atomization of coal-water slurries (CWS). In the atomization studies, the mean drop size of the CWS sprays will be determined at various air-to CWS. A correlation between the extensional and high shear properties, particle size distributions and the atomization will be made in order to determine the influence of these parameters on the atomization of CWS.

Rheological properties essential for the atomization of coal water slurries (CWS). Quarterly progress report, December 15, 1993--March 15, 1994

Description: During the past quarter, further rheological testing of the CWS were performed. The testing included low and high shear measurements. Oscillatory measurements were also planned, but the Haake CV20 accessory needed for this measurement has not yet been delivered. The CWS tested were PSOC-1527 from Middle Kittaning, PSOC-1472 from Lower Banner and PSOC 1475 (Elkhorn No. 3). The test results indicate that PSOC-1527 coal slurried much better than the PSOC 1472 coal. The rheological data is shown in… more
