Reducing the emission. - CO, CO2, NOx .
500yen scale burner
Increase the efficiency - Heat
recirculation (ex heating injected air ..)
Swiss roll combustor
MEMS power source - energy density is higher
than battery
13
Reducing the emission. - CO, CO2, NOx .
Increase the efficiency - Heat
recirculation (ex heating injected air ..)

• Flameless combustion with liquid fuels - very
  low NOx emissions
• Formation of spray
• Vaporization of the spray
• Mixing with the surrounding oxidizer (air)
• Ignition of the mixture
• Burning

• Assignments 15
• Quizzes 20
• Mid-semester exam 25
• Final semester exam 40
• Possibility of surprise quizzes
• Late submission of assignment unacceptable
• Poor attendance will fetch a special bonus (early
  grade)
