Briquettes versus Pellets
Considering whether you should chose briquettes or pellets? Here are some arguments to why briquettes are an attractive alternative to pellets – because each has its advantages.
- The main advantage of chosing briquettes is the tolerance and variety of raw materials that can be used.
- Another advantage of briquetting is the lower investment and operation costs, which are normally significantly lower.
- Usually briquette plants start from capacities of 250kg per hour and up, while industrial pellet plants start from 2000kg pr. hour.
- The fuel values or calorific values for briquettes and pellets are similar.
For a quick overview, look at the following table:
|Preparation of raw material*||Briquettes||Pellets|
|Requirement for max particle size||20x5x3mm||2x2x2mm|
|Requirement for moisture content||6-16%||10% +/-0,5%|
* Industrial briquettes and pellets
|Power consumption||35kW per ton||90kW per ton|
|Wear - spare and service parts - clean wood||2 Euro per ton||5 Euro per ton|
|Wear - spare and service parts - abrasive materials||5 Euro per ton||10-15 Euro per ton|
|Man power||1 hour per 24 hour operation||24 hours per 24 hour operation|
* Data based on briquetting press with approx 1500kg per hour
** Data based on general information. Specific data should be obtained from the pellet press manufacturer
|Data of briquettes and pellets||Briquettes||Pellets|
|Max. obtainable density||1,2||1,2|
|Max. obtainable bulk weight per m3||650kg||700kg|
Our claim is that you can supply your densified biomass to the energy plants at a lower price by making briquettes instead of pellets.
