Pulverized-fuel combustion is a complicated phenomenon which involves many subprocesses. The subprocesses which govern combustion include turbulent gas-phase chemistry and particle dispersion, radiant heat transmission, and fuel devolatilization/oxidation. A comprehensive numerical description of pulverized-fuel combustion necessitates an accurate description of these subprocesses. Earlier work done at Brigham Young University has led to the establishment of a comprehensive combustion model: PCGC-2. Several different systems have been simulated with this model. Extensive data comparisons have been used to validate code predictions. Here, PCGC-2 was used to investigate the complex flow patterns inside a small-scale test reactor for a reacting and a non-reacting case. Also, PCGC-2 was used to analyze erosion characteristics for particle laden flows in various geometries. This work illustrates the use of a comprehensive simulation model to evaluate various process questions.
