Abstract
ABSTRACTHydrocarbon fuels have high energy density which is used to run small-scale mechanical systems. The present work emphasises on experimental investigations carried out on thermal characteristics of a small-size one turn Swiss roll combustor. Parameters investigated were namely equivalence ratio, flow velocity, combustors depth, flame stability, flame locations (flash back, stable and blowout), combustor surface temperatures, temperatures in reactants channel and temperatures in products channel. Flame stability was observed at the highest flow velocity of 32.75 m/s and at the maximum heat loss of 39.16 W. Values of volume flow rates of liquefied petroleum gas used during tests were 0.25 LPM, 0.3 LPM and 0.45 LPM. Combustor model with four depths was tested. Flame stability with higher heat loss and higher velocity was observed for the combustor of D21 and D5 models, respectively. The present combustor can be used as a heat source input to the thermoelectric device.Abbreviations:LPG: Liquefied petroleum gas; MLPG: Volume flow rate of LPG, LPM; MAIR: Volume flow rate of air, LPM
