Feasibility of the Electric Energy Production through Gasification Processes of Biomass: Technical and Economic Aspects

Biomass is one of the main sources for energy production, indeed, due to its chemical and physical peculiarities, it can be used very well in thermo chemical processes such as combustion, pyrolysis and gasification. Furthermore, the considerable variability of bio fuels that can be produced allows the experimentation of new technologies that with a higher performance are able to produce not only heat but also electric power. On the other hand, due to problems in supplying and technology, the main disadvantage of such energetic system consists in its difficult application in a large scale production. The present study aims to highlight the possible use of biomasses in small energetic districts such as Viterbo area: the exploitation of wood and cellulose biomasses are described and the possible application with flowing bed technology is considered. This study wants to technically test the feasibility of a biomass supplied system, taking care of stocks availability and amount, use of gasification process based on flowing bed technology, chemical characteristic of syngas and energy power production.
