2. INTRODUCTION/BACKGROUND
• Jatropha curcas
• Plant oil is a promising alternative source
• In Nepal, the most well-known liquid cooking fuel is
kerosene

7. DESIGNS OF STOVES USING
JATROPHA
• Seeds, Kernels
• Jatropha oil in pressure stove
• Jatropha oil in wick stove
12/11/2012 7

8. MODIFICATIONS
• Round wick of 6.3 to 6.5 mm placed in a loosely
fitting tube (tube diameter = wick +1mm)
• Length of wick holder cut to make 4.5 cm (from oil
reservoir to fire zone)
• Soaking the wick

9. SPECIFICATIONS OF MODIFIED
JATROPHA WICK STOVE
• Fuel tank: 1.5 L
• With exposed multi wick burner mechanism
• 10 cotton woven wicks each of diameter 5 mm
12/11/2012 9

10. RESULT
• The fuel tend to transport very finely up to <5 cm,
once it cross 5 cm it got slow and at 7 cm there was
almost no fuel

11. CONCLUSION
Pure jatropha can be used as fuel in stove
technology with out blending any percentage
of kerosene.
