Why is charcoal considered a better fuel than wood? What are the disadvantages of converting wood into charcoal?
Charcoal is considered a better fuel than wood because:
- It has high calorific value.
- It does not produce any smoke.
- 1 kg of wood on destructive distillation produces only 0.25 kg of charcoal making it an expensive fuel.
- For production of charcoal, more and more trees would have to be cut down which causes deforestation and disturbs the ecological balance of the Earth.
