The coal-water fuel (CWF) is specified as the design fuel for vortex combustors (VC) currently being developed. From our project (VC cold flow modeling) point of view, we took initiative in developing the proper CWF nozzles for VC applications. In the development of CWF-firing vortex combustors, the atomization test of CWF nozzles represents a critical step of the experimental work. The atomization quality of CWF can directly affect the ignition of CWF, flame (combustion) stability, and burnout of CWF. The following parameters were used to characterize CWF atomization quality: (1) the relationship between the CWF flow rate and the nozzle pressure; (2) the CWF atomization cone angle; and (3) the CWF/air mass flow ratio. 6 refs., 12 figs., 6 tabs.
