Data about pellet firing
At installation the unit shall always be adjusted with a flue gas instrument and not only with help of
the human eye. When the installation is in place and has been gotten into shape with a flue gas
instrument, ask for a print of the check measurement from the installer. There you should be able to
read the values like CO, O2, CO2, combustion efficiency, draft, flue gas temperature etc.
Goal values:
CO2 : 11%
CO :10 - 300 ppm
O2 : 8-10 %
hPa : -0,10 / -0,15
General facts about fuel pellets
A fuel pellet is per definition
a”short cylindrical item” for combustion. Fuel pellets are made by
pressing of finely powdered dry fuel that is made by waste products from the forest industry. The
diameter of the fuel pellets existing on the Swedish market today, vary between 6-8 mm. The effect
on the outer environment is minimal at combustion of pellets. At the combustion in a pellet system of
for example a pellet boiler or stove the stored sun energy in the raw material is released. The
emissions of unburned hydrocarbons as well as dust are in almost all cases far below the marginal
values of the authorities. The carbon dioxide taken up and captured during the growth of the trees is
released in the process to once again be taken up by the nature. In other words a circuitry.
Combustion of pellets does not provide the atmosphere extra carbon dioxide which happens at
combustion of the fossil fuels oil, gas and coal.
