Direct burning of a diesel oil-shale slurry containing up to 2.5 wt% o
f diesel has been studied. We used an air-atomized nozzle mounted on t
he bottom of a vertical 30-cm diameter segmented combustor. The heat-t
ransfer rate distribution to the water jacket and flame stability impr
oved as the percentage of oil shale in the diesel fuel was increased.
Stable flames were observed for up to 20 wt% of oil shale.
