  • Biomass energy advantages and disadvantages

    2021-3-16u2002·u2002Advantages of biomass fuel Good burning effect. Biomass fuels have high heat value. For wood pellets, the heat value is 4300-4500 kcal/kg. For crop pellets, the heat value is 3500-3800 Kcal/kg. Although they don't reach the coal's 4900 kcal/kg, with less ash and slag residues, their heating effects are similar with medium coals.
