Characterization of industrial solid wastes and agricultural residues for energy production in Vietnam

Abstract

Solid wastes from the industrial and agricultural sectors have been recognized as in situ and alternative fuels in addition to fossil fuel resources. However, in order to choose appropriate technologies to combust such “wastes” for energy production under a stable perational condition in an environmentally aceptable manner, there exists a need for getting
insight of their initial compositions as well as the ash constituents after their complete combustion. In this study, 6 types of industrial solid wastes and agricultural residues widely available in Vietnam werecollected and analyzed. The results obtained from the proximate and ultimate analyses of these materials have shown their good fuel quality in terms of volatile content and heating value. On the other hand, their ash analysis results could help identify certain difficulties
in design and stable operation of the energy systems in which these wastes are gasified or burnt.
