Burn old wood, traces of resin or toxic products

[Noah]

Bonjour à tous

I warm myself in the woods in Brussels by recovering old pieces of furniture and old timber coming from the destruction of house frames.

I wonder two things:

- if the softwoods that I use that are often over thirty years old (I also had oak more than 200 years recently!) are completely empty of their resin and therefore are not bad for my chimney and for the environment? Are they empty of resin?

-If the varnished, polished, treated woods that have more 30-40-50 years as for the debris of old furniture that I recover at the end of the flea market are harmful given that after so much time, the products used have been largely degraded by the air? Are the substances degraded?

In one way or another I feel my functioning as clean given the lack of transport and the second life given to materials

thank you for your reply

I repeat :
For Noah and many others, burning wood with old treatments based on chlorine-based 1944 (over 50 years of PCB PPB, etc. often totally indestructible, apart from slight evaporation) is very harmful, because you make dioxins and other pollutions!
Bringing wood out of seawater full of salt (NACl) with this chlorine also makes dioxin and other pollutions !!

To avoid, you pollute yourself and your neighbors !!

Type on google: dioxin, PCB, PPB, wood insecticides, wood treatment, treated wood burning, and read everything and learn !!

Tape peat Irish sea salt dioxin also in English !!
When in Ireland they burned seaside peat full of sea salt they were filled with dioxins following studies that studied the resistance of these inhabitants to dioxin much better for men than for cows.

Absolutely, see my exchange with aerialcastor this day: https://www.econologie.com/forums/securite-d ... 59-30.html

[Noah]

ok ok I understand for the wood treatment

What does sea salt do in response?

And my second question?

After many years of drying, does the resin "go" away from the tree?

[Christophe]

After many years of drying, does the resin "go" away from the tree?

No I don't think so, or very little: they are stabilized and "eternal" chemicals ... as said above, we have been doing some nice chemical shit since the 50s ... since 1990-2000 things are going better, we become aware of the health problem ...

Otherwise I think that the term resin is poorly chosen because the fir naturally contains resin.

For example, railroad logs treated with creosote are carcinogenic "for life" ... avoid spitting in your garden, especially near the vegetable patch ...

There are several simple ways to see if you burn junk with your wood:
- the smell (pungent and pungent = not good)
- the color of the flames (green = chlorine for example = not good)
- the appearance of fumes (too black or yellowish = not good for example)

The problem is that not all pollutants are seen so easily.

[Noah]

no no, I am talking about the resin naturally present in conifers, the seve in other trees.

We normally avoid this wood to heat because it strongly clogs the chimneys but I wonder if when the conifer is very old it contains less resin.

so for an untreated fir wood but very very dry I specify

[Christophe]

Natural resin is present in all conifers: dry, it increases the calorific value of wood and increases the rate of combustion. That's why the softwood does not last long in a stove.

This also clogs the chimney a little faster than beech or hornbeam but oak also clogs a lot (tatin) if it has not been "washed" for 2 years, ie left dry without protection so that the rain decreases tannins.

Most oaks are not sold well washed.
I have personally experienced it.

In all cases, the natural resin has nothing to do with the level of danger with all the treatments that the wood could have suffered.

Sea salt is sodium chloride, so there is chlorine that can potentially make dioxins.

Do not burn your garbage in the open air:
http://dindiu.canalblog.com/archives/20 ... 70948.html

Apart from that, a single fire of 50 kg of plants equals in particles to: 8500 km traveled by a recent gasoline car, at least 40 trips to access the nearest waste disposal center, 4 half months of heating a pavilion with fuel boiler, half a day of open fire, or 16 days of heating a pavilion with a recent wood boiler.
If all the owners of a pavilion in the Grenoble conurbation make a single fire of this type per year, they will emit as much dioxins and furans as the household waste incinerator to burn our waste for 43 years to the current standard.

Eggs scrambled with dioxin
http://blogs.lesoir.be/empreinte-eco/20 ... a-dioxine/

A new study involves hen houses of individuals. Eggs from private farms are contaminated in 75% of cases. Dioxins are found in abundance ......
In any case, it is indeed soil pollution related to combustion (garden fires, incineration of plastics, ash deposit, old pollution ...) which is at the root of the contamination of the food chain.

because everywhere the grounds of the gardens where hens peck are contaminated with dioxin and other junk !!

PVC and dioxins?
Any combustion contributes to the formation of dioxins if it is carried out in the presence of chlorinated compounds, including table salt. The same amount of dioxin is produced during the incineration of waste, with or without the presence of PVC.

Read this very serious report:
inventory of dioxin sources:
http://www.chem.unep.ch/POPs/pcdd_activ ... F-2005.pdf

More than 80% of the sources come from uncontrolled combustion and heating and 70% in the air !!

dioxin due to salt in the wood it remains to prove: the salt does not decompose with the heat it will remain in the ashes

dioxin due to pvc: it's on! unless the fire is heated to a temperature sufficient to decompose, as in a good boiler full of dry wood that burns well

so I think a little bit of mixed demolition wood has a lot of good wood will not make dioxin

the worst thing to do is to burn the painted or heaped wood in heaps outside: the complete decomposition temperature is never reached and the catastrophic pollution

Another problem: the old lead paint: the lead by dust in the smoke ... but if we let the lead-painted wood let the lead compounds polish the ground also ...

so I burn the little dubious wood that I have only in full winters when it is necessary to make a big fire with a lot of good wood, a little dirty wood goes unnoticed

dioxin due to salt in the wood it remains to prove: the salt does not decompose with the heat it will remain in the ashes

At the combustion temperature of the hearth part of the salt will become liquid (at 801 °) and this should greatly facilitate its evaporation in hot gases and allow unwanted chemical reactions ....
