Effect of Heat Recirculation in Biomass Flame Stability within aCylindrical Micro-Combustor

Flame stability inside a cylindrical micro-combustor was studied. Considering the occurrence of heatrecirculation, the respective relations were written; with parameters such as motion speed of reactants,flame propagation speed and thermal conductivity of the combustor wall. The flame stability as well asits location inside the micro-combustor were also studied. It was found that for each thermalconductivity of the combustor wall, there was only one point inside the micro-combustor. If the flamewas formed in that point, it would remain stable inside the micro-combustor. It was also found that foreach thermal conductivity of the combustor wall, the flame inside the combustor remained stable, onlyin one specified range of motion speed of the reactants. In addition, blow-off limits were obtained forhigh and low speeds of reactants inside the combustor for different values of thermal conductivity ofthe combustor wall
