Paper id 149

  1. 1. Energy recovery from used transformer oil for small power generation Presented by Pritinika Behera National Institute of Technology, Rourkela, Odisha-769008 Presented in ICAER 2013, IIT Bombay, Mumbai
  2. 2. Energy from waste  One method of producing alternative energy Gives an option for recycling Reduces environmental pollution Presented in ICAER 2013, IIT Bombay, Mumbai
  3. 3. Transformer oil  Insulating oil  Helps for cooling the transformer Presented in ICAER 2013, IIT Bombay, Mumbai
  4. 4. Original Transformer Oil  Transformer oil is highly refined electrical insulating oil.  Now a days transformer oil are made vegetable oil based Presented in ICAER 2013, IIT Bombay, Mumbai
  5. 5. Oil deteoriation  Contaminated and disposed  Small quantity are used in lightening purpose Presented in ICAER 2013, IIT Bombay, Mumbai
  6. 6. Used transformer oil (UTO)  A solution to reuse the used transformer oil disposed from electrical power stations.  Used transformer oil is proposed as an alternative fuel in a compression ignition engine in this study. Presented in ICAER 2013, IIT Bombay, Mumbai
  7. 7. Chemical composition of the UTO and diesel Description C (%) H (%) N (%) S (%) O by difference (%) Diesel 86.5 13.2 0.18 0.3 0 Presented in ICAER 2013, IIT Bombay, Mumbai UTO 89.95 9.19 0.03 0.35 0.44
  8. 8. Physical properties of UTO Property Kinematic viscosity Flash point Fire point Pour point Density Lower calorific value Sulphur content T10 T50 T90 T100 Unit cSt@ 270C oC °C °C kg/m3 kJ/kg % °C °C °C °C Presented in ICAER 2013, IIT Bombay, Mumbai Diesel 2.4 76 56 -16 860 44800 0.05 210 230 260 350 UTO 13 150 172 -16.7 890 39270 0.020 320 340 370 360
  9. 9. Operating parameters Most important parameters are  Injection pressure  Injection timing  Compression ratio Presented in ICAER 2013, IIT Bombay, Mumbai
  10. 10. DAS Gas analyzer Load cell Engine Air box Smoke meter Alternator Experimental set up Presented in ICAER 2013, IIT Bombay, Mumbai
  11. 11. Result and Discussion  Combustion parameters  Performance parameters  Emission parameters To evaluate suitable operating parameters for Diesel engine in terms of different injection timings Presented in ICAER 2013, IIT Bombay, Mumbai
  12. 12. Variation of cylinder pressure consumption with crank angle Fuel with advanced injection timing shows higher cylinder pressure Presented in ICAER 2013, IIT Bombay, Mumbai
  13. 13. Variation of ignition delay with load The higher viscosity of UTO results in shorter ignition delay compared to diesel Presented in ICAER 2013, IIT Bombay, Mumbai
  14. 14. Variation of heat release rate with crank angle Retarded injection timing exhibits lower rate of pressure rise due to reduced ignition delay Presented in ICAER 2013, IIT Bombay, Mumbai
  15. 15. Variation of combustion duration with load Lower combustion duration is observed due to shorter ignition delay Presented in ICAER 2013, IIT Bombay, Mumbai
  16. 16. Variation of exhaust gas temperature with load The exhaust gas temperature is lower for advanced injection timing due to the occurrence of combustion earlier. Presented in ICAER 2013, IIT Bombay, Mumbai
  17. 17. Variation of NO emission with load Higher combustion temperature results in higher NO emission Presented in ICAER 2013, IIT Bombay, Mumbai
  18. 18. Variation of smoke density with load The retarded timing of UTO shows higher values of smoke emission due to incomplete combustion and poor atomization Presented in ICAER 2013, IIT Bombay, Mumbai
  19. 19. Conclusion Due to variation of injection timing • Engine was able to run with 100% UTO when the injection timing was advanced and retarded. • Based on the combustion, performance and emission the optimum injection timing is found to be at 20obTDC. Presented in ICAER 2013, IIT Bombay, Mumbai
