Explain the process of producing charcoal biofuel. Water initially at 20 °C and having a mass of 100 kg is to be heated to 100°C in a boiler using charcoal as fuel. Charcoal has energy density of 25 MJ/kg and water has a specific heat capacity of 4.2 kJ/kg-C. How many kilograms of charcoal is needed if boiler efficiency is 30%?
