This quarterly report describes work on the design, fabrication, and testing of a new device for atomizing coal-water fuels. The device is referred to as an opposed-jet atomizer, and differs from conventional atomizer designs in that the atomization results largely from the collision of two opposing streams of CWF flowing towards each other. Normal to the plane of the opposing streams of CWF, a blast of air crosses the colliding streams and not only aids in the atomization, but also directs the spray into the combustion zone of a combustor. The project is divided into 11 tasks. The device is first to be designed, and a rough prototype built. Next the atomizer is to be tested using water, and after successful atomization of water, CWF will be atomized under cold-flow (i.e., noncombustion) conditions. Upon review of the cold-flow testing, and after any modifications are approved and incorporated into the atomizer design, the actual atomizer will be fabricated and tested under actual combustion conditions. An evaluation of the combustion results will determine the effectiveness of the opposed-jet CWF atomizer. Results are described. 3 figs., 8 tabs.
