The result of ultimate analysis validates both ash and moisture content which are found to be 4 and 30% and 9.9 and 12%, respectively. Other elemental compositions determined by the ultimate analysis are respectively carbon (66.964% and 45.19), hydrogen (5.71% and 3.85), nitrogen (0.822 and 0.558%) and oxygen (12.604 and 8.402%). The performance test carried out on both the sawdust and palm kernel shell indicates the heat energy input of 28,125 and 31,633.06 kJ, power input of 7.812 and 8.79 kW, power output of 5.47 and 6.15 kW and the respective gasifier efficiency of 93 and 67.4%. The study has identified that the sawdust and palm kernel shell are suitable for the designed and fabricated updraft gasifier. This gasifier has been made to meet various energy demands from the local readily available materials and can be developed for various applications of heating, electricity supply and can be used to generate the needed combustible gases during fuel scarcity.]]> http://scialert.net/abstract/?doi=ijmsaj.2012.21.42 25 May, 2013 Development of Automatic Stopper Device for Commonly used Centrifugal Pumps in Egypt http://scialert.net/abstract/?doi=ijmsaj.2012.43.49 25 May, 2013
