:: Briquette - What it is and what it's good for

The briquette (ecologic firewood) is a product obtained from the mechanic compaction of several leftovers (sawdust and maravalha). It constitutes an excellent energetic substitute to combustibles such as firewood, oil, charcoal, and mainly electric energy.

Characteristics of the product:

- Low smoke generation due to the ash, soot and small percentage of humidity;
- It is necessary to bring down 10 trees in order to produce 01 ton of coal;
- 01 ton of briquette corresponds to 07 m3 of common firewood approximately;
- the briquette is a product made using reforestation sawdust and exotic species as pines;
- High calorific power;
- greater flame temperature;
- thermal Regularity;
- easy to manipulate;
- Less space needed for the storage;
- Minor pollution rate in relation to the vegetal and mineral coil, firewood, oil etc.;
- Ecologically correct reduces considerably the deforestation.

:: Advantages of the Briquette

- Less direct and indirect costs;
- Less workmanship;
- Bigger stability and rapidity in the reply of the temperature;
- Bigger hygiene and better appearance;
- Industrialized, available Product all year round;
- Ecologically correct Product;
- High heating power;
- Flexibility of use: domestic and industrial use;
- Minor pollution Generated to the environment in relation to its competitors (vegetal and mineral coal, firewood, oil diesel);
- Product manufactured through the exploitation of forest residues.

COMPARATIVE CHART ECOLOGIC FIREWOOD® x COMPETITORS

Product	Density	Residual Humidity	Heating Power	Energetic Concentration
Briquette or Ecologic Firewood	1.226 ton/m3 **	8,69%**	4.515,04 kcal/kg**	5.419 a 6.322 kcal/dm3**
Common Firewood	0,50 ton/m3*	25%*	3.600 kcal/kg*	1.800 kcal/dm3*
Coil	0,30 ton/m3*	10%*	6.500 kcal/kg*	1.950 kcal/dm3*
* Approximate Values (fonts Internet). ** Tests made in the Central Analysis Laboratory of the UFSC (Federal University of the State of Santa Catarina).

Conclusions:

I) Density:
In relation to the firewood it is 145% more dense than coil and 309%.
II) Humidity:
The briquette has its residual humidity inferior to all the other competitors in the chart above.
III) Heating Power:
It is 25,42% more efficient compared to the firewood and 43,96% less than coil.
IV) Energetic Concentration:
It is 252% more efficient than firewood and 224% more efficient than coil.

The energetic efficiency is what must be considered in the relationship cost / benefit, since all the products have as a main objective the energy generation, for this the briquette is more efficient than its competitors.

:: Forms of Use and Burn

- Using the same lighting up system already used for the briquette system;
- No need of special equipment.
- Each furnace is already set for the briquette’s burning.
