Assessment of Rice Husk Biomass Potential for Power Generation in Pakistan

Abstract

Rice husk is one of the utmost obtainable feedstock for renewable energy production and can contribute to resolving energy scarcity and environmental problems. Appropriate knowledge of the rice husk's physiochemical properties is essential for the approach of thermochemical conversion systems. The present study delivers data on proximate and ultimate analysis and heating values of rice husk collected from different regions of Sindh, Pakistan. Moisture content was found low ranging between 12.76% to 13.50% (Mean 12.98%), higher volatile matter in the range of 55.77% to 62.88% (Mean 61.19%) and ash particles of 14.50% to 16.48% (Mean 15.20%). The lower concentrations of nitrogen, 0.37% to 1.31%, (Mean 0.70%) and sulfur, 0.02% to 0.19%, (Mean 0.11%) environmentally deal with more appropriate fuel properties. The heating value of rice husk ranges varied from 5,276.33 to 6,237.13 Btu/lb (Mean 5,859.87 Btu/lb). The significant values of the rice husk samples indicated that the locally available renewable resources can be transformed into an extensive amount of energy products at a small level from active conversion techniques. Therefore, rice husk can be deliberated as appropriate fuel for energy generation and can be considered as an environmentally friendly and economically feasible fuel that helps to decline harmful pollutions.
