Wood pellet


High quality wood pellets are pellets which can be used in both small and large boilers without problems and only produce a minimum of ash. To meet these requirements pellets should be made from pure and untreated wood without bark and without use of additives. The European standard EN 14961-1 Solid biofuels – Fuel specifications and classes –
Part 1: General requirements describe the principles in general for the specification of solid biofuels regarding origin, form and properties.
In the European standard EN 14961-2 Solid biofuels –Fuel specifications and classes - Part 2: Wood pellets for non-industrial use wood pellets are further classified into 3 grades.

For the wood pellet using CARBOROBOT boilers are appropriate.

In aspect of the heating boiler construction there is two main biomass pellet group:

Wood pellet made from woody materials,(mainly sawdust)
Agripellet (agropellet) made from agricultural biomass.

The most important different between the two pellet types is the ash content. The wood pellet have 05-1% ash and the agripellet have 3-10% ash. For the wood pellet designed boilers not recommend to use agripellet due to high ash contetnt. The agripellet cheaper than woodpellet.

The raw material for wood pellets can be
- woody biomass,

Pellets are usually manufactured in a die
The total moisture is usually less than 10% of their mass

BIOfuel pellet EN 14588, term 4.23
- densified biofuel
- made from pulverised biomass with or without pressing aids
- usually with a cylindrical form,
- random length and typically 5 to 40 mm, with broken ends
