The Penn State/ERDA Coal Sample Bank was expanded to include 201 new coal samples. A total of 68 characterized coal samples and 115 selected printouts of coal data were supplied upon request to the coal research community. Selected chemical and petrographic properties were statistically analyzed for 119 coal channel samples chosen from the Penn State/ERDA Coal Data Base. Installation of the pressurized laminar flow isotherml reactor has begun. Experiments have continued on the combustion pot; the study of the reactivity of a Koppers Company coke is now complete. Studies show that weight changes associated with preoxidation can be precisely meausred using a TGA apparatus. Water densities determined on 19 coals were lower when measured in the presence of a wetting agent. Study of the effect of reaction temperature on gasification of Saran carbon in air shows one percent platinum loading on Saran carbon increases gasification rates over the entire range of carbon burn-off. Study of the theoretical aspects of combustion of low volatile fuels was resumed. The computer model was expanded to include the effects of heat loss through the furnace walls and its effect on flame temperature profiles. Investigation of the combustion characteristics of coal-oil-water-air fuel mixtures was continued. Only through the use of non-equilibrium experiments can certain important combustion characteristics be studied, and computerized data acquisition is being developed to fully implement such methods.
