摘要: Abstract The wood energy conversion into power and heating processes concerning the chips pellets production chain is analyzed. An exergy analysis a life cycle assessment are performed, considering for electricity generation in central plant distributed generation. consumption of diesel oil, biomass itself were carried out along both chains. results showed best way to avoid destruction environmental impacts based on carbon dioxide emissions. Considering same efficiency, exergetic performance impact very close when technological routes compared. However, taking account high efficiency characteristic micro cogeneration plants (combined heat power), route presents better performance. Also, sensitivity stages have demonstrated that large variations about 50% specific fuel represents small influence overall order just 1.5%.
