Whose calorific value is higher, sawdust pellet or stalk pellet?

There are various materials that can be used to make biomass pellet fuel. The calorific values of different raw material are different. Therefore, the finished pellet fuel made by different materials contains different amount of energy. As the manufacturer of  many different kinds of pellet making machines, we often receive phone calls from the investors who want to buy pellet machines. One of the most frequent asked questions from them is about calorific value of pellet fuel made from different raw material: whose calorific value is higher? Sawdust pellets or stalk pellets?

To answer this question, let’s take a look at the data about calorific value in the following content:

The heat of combustion of crop straw pellets is about 3000 to 4200kcal/KG;

The calorific value of sawdust pellets is around 4200 to 5000kcal /KG.

According to the information that I listed above, we can clearly know that the calorific value of sawdust pellets is higher than that of stalk pellets.

What’s more, there are also a lot of people asking if sawdust pellets and stalk pellets can be made by the same pellet making machine. Here, E.P will give you the answer. If you use E.P pellet making machine to produce, we can say that it is okay that you use one machine to process different kinds of materials into pellet fuel. However there is one thing you should notice. Compression ratio of different materials are different, so for processing different material, you should use matching molds. In other words, you can buy a pellet making machine with several molds to make different pellet products.
