| Abstract | The main objective of this study was to investigate the perfo1mance of a hybrid updraftdowndraft wood gasifier. The gasifier produced high-tar updraft gas stream and a tar free downdraft gas stream. The downdraft gas was also characterized by high CO and low H2 concentration. A three-cylinder, Perskin diesel engine was tested at a constant speed 1500 rpm on both diesels alone mode and dual fuel mode. The maximum energy input from the producer gas was 90.81 % of the total input. The maximum efficiency of the engine-generator set achieved with dual fuel operation, was 13.85 % at an electrical power output of 6.84 kWe. Another objective of this study was to investigate the feasibility of small-scale charcoal production by using a counter current moving bed reactor. The counter current moving bed reactor basically acted as the updraft part of a hybrid updraft-downdraft gasifier. The charcoal produced in the reactor could be removed from the bottom in small quantities at regular intervals, while flaring the gas emerging from its top. The maximum yield of charcoal obtained was 30.3%. |
