1 000 wood boiler tomorrow?

Renewable energies except solar electric or thermal (seeforums dedicated below): wind turbines, energy from the sea, hydraulic and hydroelectricity, biomass, biogas, deep geothermal energy ...

I agree with you a little bit about wood heating, but like in many areas, at the start we only look at and highlight one point, in this case, the renewable energy aspect.
It should not be forgotten that burning wood also produces particulate emissions which may not be annoying outside urban areas, but .......

This is my comment



so what!!!!!!!!!!!!!!! : Evil: it's not in the city we can rot the bouzeux : Shock: : Shock:
There are a lot of these rotten reflections, have ended up with incinerator, nuclear power plants, discharges of 80Ha !!!!
WHEN WILL THE SHIT BE MADE WHERE IT IS PRODUCED !!!!!
valid for treatment centers (in the city center : Cheesy: )
the crisis is over

I do not know where this extremely low figure comes from since in France 38 million m3 of wood are commercially exploited per year + rural self-consumption (a few million).

In any case, the 1000 boilers represent very diverse realities from the raising of chickens to the stationery passing through an apartment building.

In addition, a large part of the tonnage concerns industrial units that are both producing and consuming (example sawmills with drying sheds)

Finally, the term wood energy encompasses different facets:
- the log: cut wood, split for use in a fireplace or insert
- the forest brochure: shredded trees in the forest
- the industrial plate: crushed industrial wood waste
- sawdust, used raw or in pellets
- demolition and rubble wood

knowing that each category can be used fresh or dry, pure or mixed depending on the characteristics (or tolerance) of each boiler.

I am thus aware of numerous requests to install non-domestic boilers to such an extent that the price of low quality fresh wood and sawdust explodes.

a total of 400 tonnes, it's nonsense :|
it must be only 1 product, ultra specific.

The resource is much greater; see the site of the IFN (National Forest Inventory) which made a specific study on wood energy. Their site constitutes an excellent statistical source on the French forest.

In addition, there are mutual compensation phenomena as with other resources:
- some trunks and branches formerly abandoned on the ground during operations are taken away because they are more expensive
- the high price encourage forest owners to mobilize a resource that they once neglected
- conventional industrial users (paper, panels) compensate for the increased cost of the raw material with new inputs ...

The info comes from the book "The energy of tomorrow: Techniques - environment - economy" by Jean-Louis Bobin, Elise Huffer, Hervé Nifenecker "
"The 400 tonnes is in fact the possible operating surplus in addition to the current total exploitation and always in a sustainable manner."
Where once again, we see that the figures are manipulable and that we do not know what to trust. :frown:

- the high price encourage forest owners to mobilize a resource that they once neglected


On this subject I wish to make aware that what is
become a resource, as opposed to what was considered
as a waste, is in fact a capital steals to the next
generation. We must realize that this organic matter is
vital for regenerating the soil of a cut forest
thinning or, worse, a clearcut.
Do not sue the owner to exploit a land
forester to be able to pay the charges (cadastre, inheritance costs, planting, first thinning, insurance, damage
game etc.) which are attached to it. It is therefore normal that they
wish that the production of forest land could be
mint as much as possible. It seems to me necessary to
educate them in this sense and even protect them by prohibiting
the use of this "waste".
At the moment the demand for wood is very high (although
the price of this one has dropped somewhat since storms this winter
in Germany) but that does not justify firing any wood.
