thermo-valuing the agricultural pruning residues
The solutions CAEB International suggests for handling pruning residues are:
- heat generation
The POSSIBLE USES of the prunings are:
- direct heat generation;
- transformation into pellets;
- shipping the material to big thermal power stations.
In the first two cases a perfect drying of the pruning residues is fundamental.
- Collection and direct heat generation
The collection occurs with QUICKPOWER, a small round baler that presses pruning residues in cylindrical bales (60x40 cm) with an average weight of 25 to 30 kg.
The bales have a “soft core” and in 3 to 5 months naturally reach a moisture level of 15%, so that they can be burnt perfectly.
The bales can be burnt:
a. In one piece in wood-burning furnaces with suitable dimensions;
b. Cut into pieces with a chainsaw or a bandsaw and then put into thermo fireplaces or wood-burning furnaces;
c. Chipped with BALECHIPPER and put in the THERMOSYSTEM Chip Line boilers.
- Collection, transformation into pellets and their sale
The collection always occurs with QUICKPOWER. When the bales are dry (approx. 15% moisture) they can be loaded on the conveyor of the EPS Line pellet plant, that turns them into pellets with no need for additives.
- Collection and shipping to big thermal power stations
The collection with EDY CHIPPER allows a high operational efficiency. It is a self-propelled picking-mulching machine with hydrostatic traction, front loading and a material discharge height of about 4 meters, designed to move the just chipped pruning residues onto vehicles suitable to their immediate transportation to biomass power plants.
