Testing of a 0.15 MB/H (0.15 {times} 10{sup 6} Btu/hr) exploratory vortex combustor (VC) has been conducted firing either dry ultra- fine coal (DUC) or its water slurries, coal water fuel (CWF). The purpose of the present tests are twofold: to explore the technical and operational characteristics of this model, and to establish a preliminary data base for design improvement and for scaling up to a 2--4 MB/H proof-of-concept vortex combustor. The vortex combustion concept was refined and first time reduced into practice in a small hot test model in the present study. This model has been satisfactorily operated and tested for over 150 hours with DUC and CWF. Stable ignition and self-sustained combustion could be easily achieved without the need of preheating the combustion air or CWF. Supplementary fuel was not needed except possible during the startup. This report discusses in detail the overall test system, test procedures, and results on thermal, combustion, operational, and pollution performance of the VC. 13 refs., 11 figs., 4 tabs.
