Abstract
This work present a study about estimation of lower heat value, released heat and exergy for a process of biomass combustion composed by spent coffee and eucalyptus wood chips. Parameters of reaction as, spent and chip concentration in biomass blend, moisture, air excess and temperature of combustion products are presented. A thermodynamic modeling is a proposal for the process, being presented the equations of LHV, released heat, air-fuel ratio and exergy. The influence of the reaction parameters on LHV, released heat, air-fuel ratio and exergy are presented and analyzed in graphic form. It is expected that the results and conclusions of this work will assist in the biomass boiler operation.
