| Summary: | Experiments have been completed to characterize coal-water slurry sprays generated by an electronically-controlled accumulator fuel injection system for a diesel engine. The sprays were injected into a pressurized chamber equipped with quartz windows. High speed movies, detailed data for fuel line pressures and needle lift signals were obtained as a function of time, orifice diameter, coal loading, gas density in the chamber, and accumulator fuel pressure. For the base case conditions (50% by mass) coal loading, 0.4 mm diameter nozzle hole, coal-water slurry pressure of 82 MPa (12,000 psi), and a chamber density of 25 kg/m'), the break-up time was 0.30 msec. An empirical correlation for both spray tip penetration and initial jet velocity was developed. For the base case conditions, the spray tip penetration and initial jet velocity were 15% greater for coal water slurry than for diesel fuel or water. Results of this research and the correlation are specific to the tested coal-water slurry. |
