  Exergy is a measurement of how far a material deviates from a state of equilibrium with the environment. The exergy values of the barley, oat, rye and wheat straws were determined and the influences of LHV, moisture content, ash content, S, C, O, H and N on the exergy of cereal straws were evaluated. The moisture content of the four cereal straws varied from 10% (oat straw) to 17% (rye straw). The moisture related exergy value of the four cereal straws varied from 283.954 kJ/kg (oat straw) to 479.747 kJ/kg (rye straw), accounting for 1.376-2.275% of the total exergy of cereal straws. A positive linear relationship between the exergy value and moisture content of cereal straws was observed. The ash content of the four straws varied from 1.635% (rye straw) to 4.554% (oat straw). The ash related exergy value varied from 25.912 kJ/kg (rye straw) to 111.061 kJ/kg (oat straw), accounting fo.. View More»
