Wood chips, water content
Wood chipsWood chips are biofuel made from chipped woody biomass in the form of pieces with a defined particle size produced by mechanical treatment with sharp tools such as knives. Wood chips have a rectangular shape with a length of 5 to 50 mm and low thickness compared to other dimensions.
Standardized firewoodThe EN 14961-4 norm "Solid biofuels - Fuel specifications and classes - Part 4: Wood chips for non-industrial use" determines the fuel quality classes and specifications of wood chips for non industrial use.
Wood chips are produced from the following raw materials:
- forest, plantation and other virgin wood;
- by-products and residues from wood processing industry;
- used wood. Provided used woods do not contain heavy metals or halogenated organic compounds as a result of treatment with wood preservative or coating.
Is not included in the scope of the norm EN 14961-4
- Demolition wood, defined as "used wood arising from demolition of buildings or civil engineering installations" (FprEN 14588:2010,4.52).
Wood chips moisture content, determined with the oven drying method according to the norm EN 14774, is to be equal or inferior to:
- 10% on their wet mass for artificial dried wood chips,
- 25% on their wet mass, 35% on their wet mass or more depending on the classes of wood chips
This moisture meter for biomass allows to measure water content and temperature of wood chips, barks, plant pellets, wood shavings, sawdust, miscanthus, corn cob...
This wood chips moisture tester measures the water content and the temperature of different grades wood chips, sawmill wood chips or forest wood chips.
With its hammer probe or special probes, this moisture meter allows to measure water content of round wood, split logs, wood chips, sawdust, pellets, hay, straw and cellulose bales.
