- Q: Hard coal or white coal is the common used fuel our local. Its calorific value is no more than 3600 kcal. I want to know the calorific value of biomass pellets.

A: The calorific value of hard coal is lower than corn straw pellets, let alone high quality wood pellets. The calorific value of corn straw pellets (moisture ≤5%) is about 3700 kcal/kg. For wood pellets, the value is can be more than 4300 kcal/kg. The combustion of coal is incomplete. Generally, there is still 200 ~ 300 kcal/kg left in the coal cinder after burning. However, for biomass pellets fuel, the heat value can be released in full. With integrated computation, the heat value of coal is much lower than biomass pellets. But during biomass pelletizing, it is very important to pay special attention to the moisture content. Keep the moisture content of the final pellets less than 8%, otherwise, the calorific value will be discounted.
