What Is The Difference Between Biomass Pellets And Briquettes?
- Feb 25, 2018 -

For people who want to start biomass fuel production business, they must want to learn about the field first. Some are clear about their demand as they need biomass briquettes or biomass pellets. But some others don’t. They have no idea of the differences between biomass briquettes and pellets. Here we’d like to share our knowledge regarding this matter.

Before talking about biomass briquettes and pellets differences, first we would specify on the differences between biomass and fossil fuels.

What is the difference between biomass and fossil fuels?

Fossil fuels

Fossil fuels have been utilized for thousands of years. They include coal, gas, and gasoline. With time passing by, the consumption of fossil fuels is increasing sharply, so their amount is decreasing fast. And the fossil fuels are formed over thousands or even longer years of time, which makes it non-renewable. As a result, fossil fuels become extremely precious. What’s more, the burning of fossil fuels has caused severe pollution to the air, which ultimately harms human beings. Therefore, fossil fuels must be utilized in the most important and significant areas instead of being burned.

Biomass fuels

Different from fossil fuels, biomass fuels are renewable. It generally refers to the plants. Some biomasses like grass or crops are planted every year, others like tree can grow every tens of years, so we can say biomass fuels are renewable. Besides, biomass fuels do not release harmful gases like SO2. So many countries, especially EU nations have passed laws or regulations to support using biomass fuels.

Why do we make biomass into solid fuels?

Previously people use raw biomass like wood chips for heating and burning. But other biomasses like sawdust, straw, stalk, rice husk, palm fiber, etc. are not suitable for direct use, and they often have large size that makes storage or transportation cost much higher. Besides, the direct use of wood chips sometimes cannot combust fully. In consequence, Biomass Pellet Mill and Biomass Briquette Machine are invented to make the biomass into regular shape solid fuels which are easy to use, convenient to transport and store, and have higher calorific value (heat value).

Biomass pellets

Biomass pellets are cylinder sticks made from biomass. For making both pellet and briquette, biomass raw materials should be pulverized first. The high pressure of Pellet Mill Machine can press the powdery biomass tightly and make them not easy to break.

Biomass pellets are usually utilized in home pellet stove, central heating boiler, industrial boiler, or in power plants to replace coal. They can also be used as horse bedding and cat litter.

Biomass briquettes

Biomass briquettes are sticks or blocks with large diameter and different shapes (hexagon, cylinder, cuboid, etc.) made by Biomass Briquette Machines. They are primarily for industrial use for heating. The briquettes made by screw briquette press can also be made into charcoal briquettes for BBQ because of their light weight and regular shape. They are more durable to combust and easy to transport and store.

Having learnt from the above, you may have a general understanding of biomass and fossil fuels, biomass pellets and briquettes. If you want to learn more about solid biomass fuel making, contact us at any time.
