Discover the briquette, a viable and renewable alternative to traditional fuels for use in furnaces, boilers, ovens, barbecues, ...
The briquette is a solid biofuel, derived from a manufacturing process, made from the compaction of lignocellulosic residues, under high pressure and temperature.
To meet the manufacturing conditions of the briquette, the residue must comply with an acceptable moisture percentage, and particle size (granulometry).
"Briquetting is a very efficient way to concentrate the available energy from biomass".
In the manufacture of briquette, the raw materials used can be: sawdust, wood shavings, rice husk, corn straw, corncob, sugarcane bagasse, cotton husk, coffee husk, Brachiaria hay, among others.
The diameter of the briquette for burning in boilers, furnaces, and fireplaces is 70 mm to 100 mm and with a length of 250 mm to 400 mm.
1 ton of briquette corresponds to 6 m³ of firewood with moisture between 35 to 45%. Although variable, the briquettes made in Brazil have an apparent density of 1.0 t/m3 to 1.5 t/m3, a Higher Heating Value of 4000 kcal/kg to 4800 kcal/kg, moisture between 6 to 10%, bulk density of 600 kg/m3 to 900kg/m3, volatile matter of 81%, ash of 1.2%, and fixed carbon of 18.8%.
In Brazil, sawdust has a bulk density between 140 kg/m3 to 400 kg/m3, moisture of 15% to 55% wet base, and colors ranging from light yellow from dry Pinus sp to dark brown from wet massaranduba.
The answer is simple.
To make the storage and transportation of products more effective and economical.
If the use of briquettes can replace fossil fuels, we can also see great environmental advantages.
Composite Briquette
These are briquettes produced from more than one type of residue. Their production process is the same as simple briquettes, except for the inclusion of the raw material mixing phase.
This similarity allows to equate their production costs. By producing composite briquettes, weighted averages of their properties and compositions are obtained, allowing greater quality control of the briquettes and directing their characteristics according to their final use, with maximum reduction in the introduction of additional substances.
Producing composite briquettes also avoids dependence on a single type of raw material. In periods of scarcity of residues with higher calorific value, there is the option to replace them with other residues in greater quantity, maintaining the energy efficiency of the briquettes.
Tips for using briquettes
The starting method (ignition) can be the same used for wood systems. Any Boiler/furnace that burns wood can burn BV - Vegetable Briquette.
No special equipment is needed, just check the spacing between grates.
Best way to use BV - Vegetable Briquette
| Use in | Application | Dosage | Other usage information |
|---|---|---|---|
| Boilers in General | Only Vegetable Briquette | Necessary Quantity | Feed as continuously as possible. |
| Boilers in General | Briquette with Wood Chips or commercial wood | Desired percentage of each Product | Feed the boiler with wood or wood chips and add the Briquette evenly on top. |
| Ovens / furnaces and similar | Vegetable Briquette | Necessary Quantity |
Feed with smaller and more frequent quantities. Note: In this type of combustion, pay attention to the higher need for oxygen in the grates. |
| Pizzeria Ovens | Vegetable Briquette | Necessary Quantity |
Start the fire normally according to methods and customs. Note: Higher efficiency is obtained if the fire is made under a grate 6 to 10 cm high. |
| Fireplaces | Vegetable Briquette | Necessary Quantity |
Start the fire normally according to methods and customs, refuel the fire every 50 minutes. Note: Higher efficiency is obtained if the fire is made under a grate. |
| Barbecues | Vegetable Briquette | Necessary Quantity | To use the Briquette in barbecues, the user needs to allow plenty of oxygen and start the fire with twigs (or any other way to start a fire), after that, the fire catches easily and the efficiency is higher than charcoal. Keep the barbecue at a reasonable distance, as the grilling process occurs while the Briquette is burning with clean flames. |
