This quarterly report describes work performed on the design, fabrication, and testing of a new device for atomizing coal-water fuel (CWF). 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 atomization, but also directs the spray into the combustion zone of a combustor. The project is divided into 11 tasks, each of which is intended to allow the goal of developing a workable CWF atomization device to be achieved. The device is to be designed, and a prototype built. Next the atomizer is to be tested with water. Upon achieving the successful atomization of water, CWF will be atomized under cold-flow (i.e., noncombustion) conditions. The results of the cold-flow testing are to be reviewed, and any necessary modifications to the atomizer are to be approved. After modification, if necessary, the opposed-jet atomizer will be tested under actual combustion conditions. An evaluation of the combustion results will determine the effectiveness of the device. 1 ref., 4 tabs.
