This report describes work performed on the design, fabrication, and characterization of a new device for atomizing coal-water fuels (CWF). The device is described as an opposed-jet atomizer. Two diametrically opposed streams of CWF are directed toward each other at high velocity. Normal to the opposing streams of CWF a blast of air (referred to as cross-flow atomizing air) crosses the colliding streams causing atomization and directing the spray into the combustion zone of a combustor. It has been estimated that the opposed-jet atomizer should be able to produce a spray MMD (mass median diameter) approaching 10 microns, given a suitably fine CWF. This fine a spray should then allow CWF to burn in combustors that are smaller than those used today for CWF firing. The ARC research combustor is a 1--2 MMBTU/H tunnel-type'' furnace, and will be used for combustion testing of the new atomization device. This report describes results of combustion testing of CWF. Firing rate in relation to combustion efficiency is described. 6 tabs.
