There are a number of factors that can cause smoke from a wood-burning stove, including an unswept or clogged chimney, the type of firewood burning, such as too wet wood, poor ventilation, poor pressure around the building, or insufficient chimney height and therefore insufficient extraction.
If your chimney lets out intermittent puffs of smoke, this is known as downdraught. Downdraught is usually caused by a chimney that is either not high enough or where there are high or trees nearby that affect the wind currents around the chimney.
Most of the time, raising the height of the chimney is the simplest solution to downdraught. If raising the height of the chimney doesn't work, fixing an anti-downdraught cowl will do the trick.
Wet or unseasoned firewood could also cause your wood stove to produce smoke when you light a fire. In order for firewood to burn safely and efficiently, you'll need to make sure that it is dried and properly seasoned. This means that it should be at a moisture content of 20% or less. The lower the moisture content of the wood, the better it will burn and the less likely it is to produce smoke. You can measure the moisture content of your firewood with a moisture meter.
One of the main problems with burning wet wood in a stove is that it can cause more smoke to be produced than usual. For the fire to burn the wood efficiently to produce heat, the fire needs to first burn off any excess moisture within the wood. The higher the moisture content of the wood, the harder it will be to burn. When the wood is too wet, this will cause the wood to burn less efficiently and more smoke can be produced as a result.
Small amounts of smoke can be part of the normal operation of a wood stove. If you're seeing unusual amounts of smoke being produced, check to see whether you're using wood that has been 'well-seasoned' or 'kiln dried', as these terms typically denote wood that has been dried long enough to be used as firewood.
To prevent smoke from the wood stove, it is recommended to burn the following woods:
Is darker at the ends.
Has less visible green colors.
Is lighter in weight.
Can be split at the ends.
Makes a hollow sound when hit together.
Has bark that can be easier to peel off.
