Popis: Previous studies have shown that a spouted bed can achieve clean and efficient combustion in the flame mode, i.e.. using a flame positioned on the bed surface. For comparison, a spouted bed also should be operated in the non-flame mode. To obtain improved design information and explore further applicability of such a combustor, the thermal behavior in different regions of the system have been investigated with emphasis on the bed region; it can influence the combustion performance beyond the bed surface. A non-flame mode study has been conducted by adding heaters. Results for lean propane (φ< 0·31) combustion were obtained in the bed region, at the bed surface and at the exit of the combustor. Several operating parameters — equivalence ratio, particle size, bed height, and bed material — were investigated. A critical temperature region was defined as the temperature range where conversion to intermediates and products increased distinctly. From a comparison of combustion results between the flame...
