EXPERIMENTAL INVESTIGATIONS OF FLAME PATTERNS OBSERVED FOR LPG/AIR PREMIXTURE USED IN SMALL-SCALE SWISS ROLL COMBUSTOR
SINOPSIS
The present paper discusses testing of a small-scale Swiss roll combustor with two rectangular adjacent channels. Swiss roll combustors were tested using a liquefied petroleum gas (LPG) and an air pre-mixture. The following parameters, viz., the mixture equivalence ratio, mixture flow rate, and Swiss roll combustor channel depth were varied and their effect on the occurrence of different flame patterns formed in the combustor is monitored and reported. The flow rate of LPG was varied in the range from 0.25 LPM to 0.55 LPM. Nine different types of flame patterns were observed in the combustor, viz. planar, concave (or U-shaped), conical with short height and large base, conical with larger height and small base, elliptical, triangular, circular, triangular with tail, and elliptical with tail. Triangular flame with tail achieved highest combustion space temperatures as compared to other flame types listed above. The triangular flame with tail was generally observed for maximum number of Swiss roll combustor models tested (SW10, SW15, and SW20) at a wide variety of flow rates in comparison with other eight flame types. The lowest combustion space temperature was observed for planar flame type for which flame stability was also achieved for a narrow range of flow rates. Swiss roll combustors with higher channel depths showed higher maximum temperatures compared to the lower depth combustors. A flame with different pattern/shapes is observed in different regions in the combustion space of the combustor. A planar flame was noticed below 5-mm depth combustor. The tests indicated that the flame characteristics/patterns are strongly dependent on the mixture equivalence ratio, mixture flow rates, combustor depth, and heat recirculation from products to reactants.
