Question: Repeat exercise 19 for the combustion of coal. For simplicity assume coal is just carbon, C, with a HV of 32,800 kJ/kg. Use engineering considerations

Repeat exercise 19 for the combustion of coal. For simplicity assume coal is just carbon, C, with a HV of 32,800 kJ/kg.

Use engineering considerations to give insight on the global warming issue.

Exercise 19

A monomeric formula for wood cellulose is C₆H₁₂O₆ (it repeats many times as a hexagonal structure based on this formula). The energy content by burning wood is approximately 1.0 × 10⁴ J/kg. Determine the amount of carbon dioxide released in obtaining a kJ of energy by the combustion of wood in air. (A: 1.5 × 10⁴ kg of CO₂ released/kJ of energy produced)
