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 quarter, the ancilliary equipment required to operate the opposed-jet atomizer was to be procured and assembled. The major subsystems are: feed-system for the No. 2 fuel oil, propane burner (with feed systems for propane and combustion air), feed system for CWF, atomizing air feed system, secondary air feed system, and also cooling water for the jacketed atomizer. Each of these systems is currently operational. 5 tabs.
