Abstract :

The combustion of kerosene in cooking stoves increases the risk of certain life-threatening health conditions such as cancer; respiratory infections like asthma, tuberculosis (TB) and sight defects like cataract when used indoors. The emission characteristics of jatropha biodiesel- kerosene blends were investigated to ascertain their potential as substitute for kerosene in a pressurized kerosene cooking stove. The assessments were done by comparing some of the emission characteristics of the blends of jatropha biodiesel with kerosene. The blends were categorized as B100 (100% biodiesel), BK20 (20% jatropha biodiesel and 80% kerosene), BK15 (15% jatropha biodiesel and 85% kerosene), BK10 (10% jatropha biodiesel and 90% kerosene), BK05 (5% jatropha biodiesel and 95% kerosene) and BK0 (pure kerosene). The emissions were determined using gas analyzer (NHA-506EN model). The emissions determined were CO, CO2, SO2, NOx and HC at various vessel pressures of 0.2, 0.4, 0.6, 0.8 and 1bar for all the fuel blends. The emission results revealed that BK20 blend at 0.6 bar has the least emission of harmful gases of CO=0.02%, CO2=2.09%, SO2=0.41%, NOx=5.0ppm and HC =31ppm blend. It is recommended to use BK20 fuel blend as an alternative fuel for kerosene in the pressurized kerosene cooking stove.
