Abstract
Small-scale grate-firing biomass furnaces suffer from high levels of pollutant emissions caused mainly by a low level of air/fuel mixing and a short residence time for combustion as a result of their small volume. Reliable gas-phase combustion modeling is key for improving the design of these systems. The present work describes a computational fluid dynamics study of biomass combustion using the modified eddy dissipation concept (EDC) model. Part 1 ( 10.1021/acs.energyfuels.6b01947 ) of this study focused on examining the main challenges of the EDC model regarding its application for modeling weakly turbulent and slow-chemistry reacting flows. In addition, a sensitivity analysis was carried out on the constants of the model for modeling non-premixed combustion at weakly and highly turbulent reacting flow conditions. Using the conclusions of the analysis of part 1 ( 10.1021/acs.energyfuels.6b01947 ), gas-phase combustion of a small lab-scale grate-firing biomass furnace is simulated in the present paper (part 2). The results revealed that the modified EDC model produced reasonable predictions of the temperature and gas emissions.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
