PERFORMANSI GENSET BENSIN 2000 W YANG DIMODIFIKASI MENJADI GENSET BERBAHAN BAKAR BIOGAS

Abstract

Biogass is one of energy alternative sources, produced from organic materials degradation in anaerob condition that has economically and availability advantages. This research had been conducted to convert biogass to electric power or as known as bio-electric which using a modified carburetor of gasoline genset converter. Biogas was produced from cow's manure fermentation, located at Giri Mekar Kecamatan Cilengkrang, Kabupaten Bandung. Methane (CH4) concentration was 40% from the biogass with potential energy 43,5 MJ/kg. The result showed that genset with biogass as fuel could reach 989 W output of capacity with 2,95 x 10-4 kg/s of fuel consumption and 11,9% of maximum eficiency. Compare to gasoline as a fuel, the result showed l219 W output of capacity with 1,63 x l0-4 kg/s of fuel consumption and 17,2.'% of maximum. Therefore, to have same output of capacity a genset with biogass as fuel is more consuming than genset with gasoline as fuel.
