Exergy characteristics of rice husks

“…9 rice husk sam ple has the high est ash re lated exergy value (341.03 kJ/kg) whereas it has the nine teenth low est ash con tent (15.90%). This in di cates that the ash re lated exergy of rice husk is not only de ter mined by the ash con tent but also the ash com po si tions [3,12].…”

“…The mois ture re lated exergy val ues are in the range of 0-327.93 kJ/kg. Zhang et al [10][11][12] stated that the mois ture re lated exergy of a fuel is pro por tional to the mois ture con tent of the fuel. The re sults that the first ten rice husk sam ples have the low est mois ture re lated exergy val ues (0 kJ/kg) whereas the last rice husk sam ple (No.…”

“…The S re lated exergy val ues are in the range of 0-67.78 kJ/kg. Zhang et al [3,[9][10][11][12] stated that the S re lated exergy value of fuel is di rectly de ter mined by the S con tent of the fuel, and it is shown in eq. 2that the S re lated exergy of a fuel is pro por tional to the S con tent of the fuel.…”

“…The LHV re lated exergy val ues are in the range of 10577.05-24675.63 kJ/kg. Zhang et al [12] stated that the LHV re lated exergy of a fuel is pro por tional to the LHV of the fuel. The No.…”

“…They also ob served a re la tion ship be tween exergy and LHV, a re la tion ship be tween exergy and mois ture con tent, a re la tion ship be tween exergy and ash con tent for the rice husks. How ever, the exergy char ac ter is tics and re la tion ships are strongly de pend ent on the fuel types and prop er ties [9][10][11][12][13]. A com pre hen sive in ves ti ga tion of the exergy char ac ter is tics of ex ten sive rice husk sam ples is there fore sig nif i cantly nec es sary and these ex ten sive data can: pro vide com pre hen sive exergy char ac ter is tics of rice husk and set solid foun da tion for es ti ma tion of the exergy of rice husk.…”
