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:
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.
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.
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).
