Abstract |
Converting rice husk into energy is a promising method of generating
renewable energy and reducing greenhouse gas emissions. In this research rice
hush is considered as biomass fuel. The characteristics of rice husk gasification
were investigated at an Equivalence Ratio (ER) of 0.25–0.38 and a gasifier
temperature of 750-870°C in 20 tons per day (TPD) using steam explosion
process in fluidized bed gasifier system. Different operation conditions,
temperatures and loads, are investigated for their effects on the compositions,
calorific properties, gasification efficiencies of syngas. The effects of the critical
parameters, namely, Steam-to-Biomass Ratio (S/B), Particle size variation and
gasification temperature on the quality of the product gas as well as the gasifier
cold gas efficiency were analyzed. This is the new finding in the research.
The optimal conditions of the gasification operation were an ER of 0.20 and
gasifier temperature of 800°C. The low heating value of the gas produc
