The three main tasks of this study are: (1) entrained coal gasification measurements, which include elevated pressure tests of four coal types, investigation of injector design, cold-flow measurements in simulated gasifier flows, and investigation of advanced optical diagnostic techniques that would be applied to gasification measurements; (2) improvement of the computer code for gasification processes, including improvement of physical submodels and numerical methods, and comparison of model predictions with experimental results for code validation; and (3) application of results to industrial and METC needs through technical seminars, expansion of a detailed data book, and distribution of the code to other users, especially METC. The mechanical installation of the gasifier into the new Combustion and Reactions Laboratory Building was completed, and two successful gasification experiments with Utah bituminous coal at atmospheric pressure were made. The PCGC-2 code was used to determine optimum operating conditions (based on maximum cold gas efficiency) for the existing baseline BYU injector design. The cold flow test program for simulated-gasifier operation has been completed. The evaluation of the current turbulent particle dispersion model was nearly concluded during the quarter. This model will form a benchmark with which to compare other turbulent particle dispersion models. Work on the coal devolatilization model and on coal oxidation was continued during the quarter. 34 refs., 13 figs.
