For the wood pellet using CARBOROBOT boilers
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
- 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
