Abstract

Most of the people especially in rural areas of Ethiopia have been using charcoal, firewood and animal dung for many years. Due to these, women can be affected for different respiratory diseases. The country generates huge tonnes of rice husks at different locations. The main aim of this project was to design, manufacture and optimize the continues type rice husk gasifier which will be an efficient and convenient cooking device that produce gaseous flame using rice husk as a fuel Water Boiling Test (WBT) was performed to evaluate the performance of the gasifier stove. The indoor air quality was also tested using indoor air pollution meter. The power source specially to drive the fan was solar photovoltaic (PV). For different inlet air flow rates, WBT was checked. Air flow rate having 6.51 m3/s delivers better performance of the gasifier. The newly designed model delivers the maximum particulate concentration of 229 µg/m3 and the highest CO concentration of 3.8 ppm, and average PM concentration and CO concentrations are 63 µg/m3 and 0.42 ppm, respectively. T he thermal efficiency of the gasifier for different in let air flow rates 8.94 m3/s, 7.74 m3/s and 6.51 m3/s were checked and he result comes 36%, 30% and 45%, respectively. The specific fuel consumption for the above-mentioned inlet air flow rates in g/L were 153, 234 and 169, respectively.
