This document is the first quarterly progress report on the effort to develop an understanding of the stability and carbon carryover characteristics of pulverized fuel combustors. This work is to be accomplished by improving and extending a model developed for entrained flow coal gasifier analysis by including a better description of the finite rate coal pyrolysis, pyrolysis product chemistry, char reactions, particle-particle interactions, radiative transport and recirculation/mixing. The data to be analyzed with the model will include data from simple (cylindrical symmetry) geometry combustors with premixed and mixing reactants, swirl and recirculation. The analysis of these data with the model should lead to an understanding of the effects of fuel type, swirl, recirculation, O/F ratio and mixing rate on the location (stability) of the flame and the carbon carryover from the combustor.
