Biomass pellets are a type of solid biofuel.
They are mainly made from compressed organic materials like wood sawdust, straw, and other agricultural waste.
These pellets are popular because they have a high energy density.
They are also suitable for automated combustion systems.
Biomass pellets are environmentally friendly as they are a renewable energy source.
What are the Specifications for Biomass Pellets? 6 Key Factors You Need to Know
1. Composition and Raw Materials
Biomass pellets are usually made from finely ground organic materials.
These include wood sawdust, straw, bark, and agricultural by-products.
The materials are chosen for their availability and suitability for compression into pellet form.
Pure sawdust and shavings are commonly used.
Organic additives are allowed up to 2% by weight to enhance binding and combustion properties.
2. Moisture Content
The moisture content of biomass pellets is very important.
For wood pellets, the standard requires a moisture content below 10% on a wet basis.
This low moisture content ensures efficient combustion and high energy output.
The pelleting process helps reduce moisture as the pellets are heated to temperatures between 90–105°C.
This causes moisture to evaporate.
3. Size and Shape
Biomass pellets have a uniform size and shape.
This makes them easy to handle and burn in automated systems.
The typical dimensions of biomass pellets make them suitable for transport via screw conveyors and pneumatic systems.
This enhances their applicability in small to medium-scale combustion plants.
4. Energy Density and Combustion Properties
Pellets have a high surface-to-volume ratio.
This contributes to their efficient combustion.
They burn with a steady and smooth flame due to their homogeneity and high energy density.
This makes them ideal for use in heating systems where consistent and clean burning is required.
5. Production Technology
The production of biomass pellets involves a demanding process.
It requires precise adjustment of the raw material's dimensions and moisture content.
Technologies like the flat die pellet mill are used.
In this process, feedstock is compressed between rollers and a die.
This extrudes cylindrical pellets that are then cut to size.
The high wear of the functional parts of the pelleting machines is a challenge.
This indicates the need for robust and durable machinery.
6. Environmental and Economic Considerations
Biomass pellets offer significant environmental benefits.
They are a renewable and sustainable energy source.
They help reduce greenhouse gas emissions.
They can also help mitigate the depletion of fossil fuels.
However, the investment and energy consumption required for pelleting are higher compared to other forms of biomass conversion.
Despite these costs, the advantages of pellets in terms of their suitability for automated systems and their clean combustion make them a preferred choice in many applications.
