Studies on Characteristics of Some Shrubaceous Non-woody Biomass Species and Their Electricity Generation Potentials

Abstract

This article presents the results of chemical compositions, ash fusion temperatures, and energy values of various components of four different types of surplus non-woody biomass species (viz. Eupatorium, Anisomales, Sida, and Xanphium) and their impact on decentralized power generation structure. Among these biomass species, the components of Sida were found to have the highest carbon and hydrogen contents and energy values. In general, the results indicated lowest ash contents and highest energy values for their stumps, followed by branch, leaf, and bark, respectively. The fusion temperature results have been reported to be relatively higher (1,250– 1,500ıC) for Anisomales and Sida biomass ashes, indicating safe boiler operation up to about 1,100–1,200ıC with these biomass materials. The calculation results have shown the requirements of approximately 67, 15, 39, and 64 hectares of land for energy plantations with Eupatorium, Anisomales, Sida, and Xanphium biomass species in order to ensure a perpetual supply of electricity for a group of 10–15 villages. Altogether, the authors recommend the exploitation of Anisomales and Sida biomass species for energy plantations in wastelands and their subsequent utilization in power generation, either individually or in co-firing with locally available high ash coals.
