Abstract
This study shows an exergetic analysis based on both enthalpy and exergy flow, aiming at the efficient use of biomass energy. Several technologies for heat and power derived from woody biomass can be assessed by means of exergy efficiency, which indicates work potential of energy amount. It also makes clear the lost opportunities to do work in the energy conversion process and offers plenty of room for improvement. The results show significant difference between thermal and exergy efficiencies. The largest exergy loss in biomass power plant is found at the boiler, however the largest enthalpy loss takes place in the steam turbine.
