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