Description: The main objective of this program is to understand the chemical and physical mechanisms in coal conversion processes and incorporate this knowledge in computer-aided reactor engineering technology for the purposes of development, evaluation, design, scale up, simulation, control and feedstock evaluation in advanced coal conversion devices. To accomplish this objective, this program will: (1) provide critical data on the physical and chemical processes in fossil fuel gasifier and combustors; (2) further develop a set of comprehensive codes; and (3) apply these codes to model various types of combustors and gasifier (fixed-bed, transport reactor, and fluidized-bed for coal and gas turbines for natural gas). Results are presented on the devolatilization of large coal particles; transport reactor modeling; fluidized bed model; nitrogen evolution from small and large coal particles; modeling of hydrogen cyanide and ammonia release during coal pyrolysis; oxidation rates for large coal particles at high pressures; advanced fixed-bed model development and evaluation; application of ACERC combustion and gasification codes to AFR diagnostic capabilities to systems of interest to METC; and submodel for lean premixed combustion of natural gas in industrial gas turbines.
