Wood chips for ECO20x

WOOD CHIPS COMPATIBLE WITH ECO20x

In order to obtain good working condition for ECO20x mCHP, in terms of reliability, efficiency and correct maintenance, the use wooden chips in compliance with following specifications is required:

Size G10 - G30
1,50 - 3,00 cm
Moisture percentage
15-20% (A1-P31,5)
DENSITY
>200kg/m
The chosen wooden biomass MUST be delivered without external elements like: spikes, wires, bolts and any other metallic items, stones or glasses.

WOODEN CHIPS STANDARD QUALITY

Wooden chips' quality is extremely important for the correct CHP system's operation mode. Wooden chips powering ECO20x MUST be in compliance with expected requirements of the equipment. Wooden chips compatibility is based on two main criteria:
  • Moisture degree
  • A1 quality category in compliance with EN-14961-4 and ISO 17225-4 European regulations.
Wooden chips to be used must be produced by mechanical treatment of natural wood, as referred in Legislative Decree 152/2006 "Regulations on Environment".
Wooden chips for ECO20x
can be produced by chipping:

trunks of conifers and broad leafs

broad leafs trunks with branches and without leafs

broad leaf dead branches without leafs or dry leafs

wooden chips from first wood production getting high wooden residual quantities

WOODEN CHIPS

As per the size, you can find specifications included in UNI/TS 11264 regulation.

Wooden chips shall be included between categories G10 and G30, i.e. they shall have size suitable for passing through a 30x30mm mesh but NOT through a 10x10mm mesh.

STEARIC DENSITY

An essential parameter for storage tank's size is the stearic density (kg/msr) of wooden chips, this parameter let know the ECO20x woorking time, bound to the biomass consumption rate per hour (26 kg/hour).

Stearic density depends on size and strictly on wood type and moisture degree.

TEXTILE BRIQUETTES

In comparison with conventional biomass, textile have a moisture degree within 1% -5%

The density of textile briquette is a little bit higher than the measured one for wood sawdust equal (875kg/m3).
