Abstract


Although several works on rice husk gasification in downdraft gasifier have been reported, but none of those works investigated and discussed propagation and performance of the gasification at different tuyer inclination angle. The present work aims to investigate an effect of tuyer inclination angle on propagation characteristic and performance of the gasifier fed by rice husk. Gasification of rice husk is performed in small-scale closed top downdraft gasifier at tuyer inclination angle of 0°, 30° and 60° and at equivalence ratio of 0.20. The tuyers are located at 400 mm above the grate. The highest burning propagation rate and effective propagation rate are achieved at tuyer inclination angle of 0°. The values are 0.29 and 0.44 mm/s respectively. The highest higher heating value of producer gas of 3.24 MJ/Nm3 and the highest cold gas efficiency of 78.39% are also found at tuyer inclination angle of 0°.
