Abstract
This study explores the use of carbonized rice husks (CRH) for wastewater treatment and as a fuel source, incorporating filtered fats as binders to create CRH briquettes. An automated stove was developed and tested under different fan settings (low, medium, high) and feeding intervals (1-minute, 2-minute, 3-minute), with each condition undergoing three trials with three replicates. Evaluating the automated briquette stove's efficiency in terms of fuel consumption rate and thermal efficiency revealed varying rates across fan speeds: highest at high fan speed (3.38 kg/hr), followed by mid fan speed (3.11 kg/hr), and lowest at low fan speed (1.96 kg/hr). Al, treatments showed significant differences at a p+0.05 significance level, indicating increased fuel consumption with higher fan speeds. To minimize fuel use, the lowest fan speed is recommended. Thermal efficiency remained consistent across different settings. The study concludes that the automated stove efficiently enhances the utilization of biofilter carbonized rice husk briquettes as a sustainable fuel source.
