A case study on bio fuel stove technology jatropha as a bio fuel

  1. 1. A case study on Bio fuel Stove Technology: Jatropha as a bio fuel BY: Ashok Yadav M.Sc. Env. Science Golden Gate Int’l College Kathmandu, Nepal http://www.goldengate.edu.np/12/11/2012 1
  2. 2. INTRODUCTION/BACKGROUND • Jatropha curcas • Plant oil is a promising alternative source • In Nepal, the most well-known liquid cooking fuel is kerosene 12/11/2012 2
  3. 3. PHYSICAL PROPERTIES Jatropha • Viscosity: High • Ignition Temperature: 340°C Kerosene Low 50-55°C 12/11/2012 3
  4. 4. OBJECTIVES To determine the compatibility of pure jatropha oil for burning as a bio-fuel 12/11/2012 4
  5. 5. METHODOLOGY 12/11/2012 5
  6. 6. TECHNOLOGY Two Types Of Stove Burner • VAPOUR JET BURNER • WICK BURNER 12/11/2012 6
  7. 7. DESIGNS OF STOVES USING JATROPHA • Seeds, Kernels • Jatropha oil in pressure stove • Jatropha oil in wick stove 12/11/2012 7
  8. 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 12/11/2012 8
  9. 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. 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 12/11/2012 10
  11. 11. CONCLUSION Pure jatropha can be used as fuel in stove technology with out blending any percentage of kerosene. 12/11/2012 11
