🔥 Combustion Products Summary

COMPLETE COMBUSTION

  • Products: CO₂ + H₂O only
  • Oxygen: Plentiful supply
  • Flame: Blue and clean
  • Energy: Maximum release
  • Safety: Safe products
  • Example: CH₄ + 2O₂ → CO₂ + 2H₂O

INCOMPLETE COMBUSTION

  • Products: CO and/or C (soot)
  • Oxygen: Limited supply
  • Flame: Yellow/orange, smoky
  • Energy: Less energy released
  • Safety: Dangerous CO gas
  • Example: 2CH₄ + 3O₂ → 2CO + 4H₂O
