Flame Stability Measurement on Rectangular Slot Meso-Scale Combustor
The biggest problem of combustion in the micro-scale or meso-scale combustor is heat loss. Heat loss led to a difficult of stable flame. This research aims to elucidate the flame stabilization and flammability limit of LPG-oxygen premixed flame, temperature distribution and flame visualization. Flame stabilization and flammability limit map are shows in φ - U plane. The result shows that there are six regions in the map that is stable without noise, stable with noise, transition zone, dead zone, pseudo stable, and blow off. Measurement parameters are LPG-oxygen flow velocity at various equivalent ratio and temperature. The flame stabilization and flammability limit map within measurement parameters are discussed.
