Question

Although wood has a very high calorific value, we still discourage its use as a fuel. Explain.​

Answer 1

Following reasons can be considered to discourage the use​
of wood as a fuel because​

​

• It has a high ignition value, so the combustion process of wood would be a bit tough.​
• Burning wood produces many harmful gases such as Carbon monoxide and carbon dioxide. Excess of both can kill a person, and it also causes global warming.​
• To use wood as a fuel, we would have to cut trees, which has further adverse effects on the environment.​
