WOOD & AGRO PELLETS-BRIQUETTES INTRO
Wood and agricultural pellets & briquettes are both biofuels made from compressed organic matter.
The pellets can be made from biomass (generally made from compacted sawdust).
Furthermore, the pellets are categorized by their heating value, moisture and ash content and dimensions. They can be used as fuels for power generation, but mostly for commercial or residential heating. Pellets are extremely dense and can be produced with a low moisture content (below 10%) that allows them to be burned with a very high combustion efficiency.
On the other hand, wood & agro briquettes are made of dry, untreated wood chips (e.g. wood shavings) or agricultural residues and crops. They are pressed with high pressure without any binder. By compacting the matter with this high pressure, it turns into a fuel like coal.
Advantages
Both products have a lower ash and sulfur content, compared to fossil fuels. The carbon dioxide (CO2) balance is even, because pellets & briquettes made of wood or agro matters release just as much CO2 to the atmosphere as the trees or plants used for their production once absorbed through growth by photosynthesis. In addition, they have a substantially higher energy content per cubic meter due to their density which means less storage space and more heat released per kg.
Energy Content
The low moisture content of about 10% leads to an energy content of around 5.0 kWh per kg depending on the type of matter. Green firelogs for example have a water content of around 50% with 2.5 kWh/kg energy content.

Ibres LTD promotes through its business activities the use of renewable energy sources by supply to customers know-how along with all the appropriate pellet & briquette machinery.
This sector is expanding rapidly at the last two decades and there are economic, social and environmental purposes of entering to this kind of business.
These kind of production plants (micro to medium & of course large scale) are almost all profitable, useful for the local economies and produce an excellent, low cost biofuel to cover heating purposes.
Ibres LTD has a lot of gained experience in this field via developing a lot of pellet and briquette projects.
Finally, in the next to infographics you could easily find more details about the production procedure, for pellet and briquette plants respectively.
