ABSTRACT
This paper presents the results of tests performed with an internal combustion engine adapted to MWM Otto cycle, coupled to an electricity generator with a capacity of 50 kVA, fed exclusively with synthesis gas from a biomass gasifier downdraft, using wood eucalyptus. Also featured are the characteristics and efficiency of the generator set, in order to assess the feasibility of applying the system in remote locations, where biomass is available and the system of conventional electric power transmission is hampered by distance. The synthesis gas generated showed the average composition of 16,9% H2, 20% CO, 10,9% CO2, CH4, 2% and 50,1% N2. The performance of the span was monitored by applying loads of 0, 7, 13, 20,1 and 26,4 kW, the generator, keeping the average voltage of 222 V and currents of 0, 18,5, 33, 51, 84 and 67 A.
