Abstract " )he o' ective of the stu(y is to (etermine efficiency of 'iomass 'urne(. )he 'iomasses +ere cho e( in 2 to - cm lengthan( sun (rie( to moisture content less than 20/. ach treatment +as re licate( tree time. Accor(ing to the result of the stu(y, the 'ulk (ensities of each 'iomass +as 12 kg3m 4, $ kg3m4, 2 4 kg3m 4 an( 2 - kg3 m 4 for coconut husk, stems of cassava, mul'erry an( cassiastamea, res ectively. )he (ensity of 'iomass +as highest for the cassia stamea an( lo+est for cassava an( coconut, +ith aninterme(iate value for mul'erry. &es ite these (ifferences in fee(stock (ensity, there +ere no (ifferences among sources of 'iomass inthe o erating arameters of the conversion of 'iomass to electricity, an( energetic efficiency 67asifier8. )he Re9uirement of 'iomassin energy ro(uction in one hour is $.0# kg, $.#4 kg, 10.42 kg an( 10. $ kg for coconut husk, stems of cassava, mul'erry an( cassiastamea, res ectively. ne kg of 'iomass mass (ensity can ro(uce energies as 1.11k:h, 1.21k:h, 1.1 k:h an( 1.2 k:h for
