| Abstract | ||||
| The shortage of energy and oil fuel is one of the most important challenges facing the world today. Biomass has become an important source of renewable energy. Residues are the third source of renewable energy after wind and solar energy. Farmers have incinerated of these residues causing serious environmental damage rather using this huge energy for useful purposes. The research aims to develop and test a stove powered by solid biofuel pellets. The experiments and the data analysis were carried out in the Agricultural Engineering Research Institute. Palm fronds were used in this study because it has a high calorific value and available in the desert of Egypt, also its neglected and priceless. The total availability of pruning’s from palm date production was estimated to be around 813.9 Gg/year (FAO, 2017). Solid biofuel pellets were manufactured from palm fronds. Use different fan air speeds which has low energy to take ultimate advantage of burning palm fronds pellets requires a stove with high thermal efficiency and requires sufficient oxygen for combustion. The stove was manufactured according to Winiarski’s design. The fan air speed from 0.2 to 2.2 m/s and some physical and mechanical properties of palm fronds pellets were studied. The stove performance was based on determining the combustion duration and temperature from palm fronds pellets, emissions of stove (CO2 and CO) and stove heats efficiency. The calorific value of palm fronds pellets was 17.2 MJ/kg at a moisture content of 7.4% and true density of 1250 kg/m3. The maximum combustion duration was 153 min/kg at fan air speed of 0.2 m/s. The maximum temperature was 500 ⁰C and minimum value of CO was 282 mg/m3 at fan air speed of 2.2 m/s. The optimum point of stove heats efficiency was 64.4% was obtained at fan air speed of 1.0 m/s. | ||||
