Study of thermal efficiency of biomass carbonizing by direct method
Abstract
In this study, we have designed a carbonization furnace comprising a combustion and a carbonization chamber. To know the performance of carbonization furnace, we calculated the thermal efficiency using direct method. Biomass that were used as a test material are rice husk and corn cob. We found that the highest temperature for 1.0 kg of wood fuel of combustion chamber and carbonization chamber are 648°C and 459°C, respectively. Each of the biomass has been carbonized three times at different average carbonization temperatures. It is found that the highest thermal efficiency was 2.82% and 4.43% for rice huks and corn cob, with carbonization temperature of 405.24°C and 399.80°C, respectively.
