A full combustion cycle comprises the following:
1. A short period after reloading when the wood begins to heat up without flames. The time until the flame lights
is an indication of the fireplace temperature. If you wait too long to reload firewood, the temperature falls too
low and the new load of firewood does not light well. This has a negative effect on combustion and dirties the
glass.
2. The temperature of the firewood increases rapidly, and it begins to break up, emitting gas that ignites if the
fireplace temperature is appropriate. The fireplace temperature begins to increase as the fuel emits more gas and
the flames increase.
3. After a certain period of time, which varies depending on the type of firewood, the maximum temperature
value is reached, and the gases emitted from the firewood decrease slowly along with the volume of the flames.
When the firewood gas emission is complete, the flame goes out and the firewood turns to burning embers, that
is the moment to add wood into the stove.
-
The fuel load should have the approximate weight recommended by the manufacturer for each model.
Preferably in one or two pieces.
-
Avoid overloading with firewood that is too thin as this can cause poor combustion. The firewood emits an
excessive amount of gas very quickly and the air supply is insufficient. Although there is a large volume of
flames, combustion it is not good, and the glass tends to get dirty. There is a danger of reaching excessive
temperatures that threaten the integrity of the wood burner and user safety.
-
Select the firewood to achieve the desired type of operation. Thin firewood should be used to get higher
thermal power, use it after lighting the fire for a faster response as you need more heat. Use thick wood
for a slower combustion when you have less need for heat or for overnight maintenance, always
preceded by a cycle of more power with thinner firewood, when the appliance temperature is already
high. If necessary, when starting the fire, burn a combination of thin and thick firewood.
-
When the wood burner is in operation, the door should always be closed. When you open the door to
reload, do so slowly to avoid the smoke inside the fireplace from blowing out into the room.
Warning. - In wood burners and inserts, prolonged and continuous use at a very low rate of
combustion or with very wet wood can cause highly flammable creosote to build up in the flue.
3.2 Fuel
Wood burner performance also depends greatly on the fuel used. The wood must be dry to get more heat (less
than 20% humidity). It will also be easier to regulate heat and keep the wood burner and flue in better condition.
Store firewood in a dry, ventilated place protected from the rain for at one to two years depending on the storage
and weather conditions.
Use opened pieces of wood, it will burn better than logs. The best would be opened pieces with a similar section
and shape.
