Pollution burning pellets or pellets

[stone-ernest]

Uh there are still some filth in the printing paper: chlorine at the head but also all the inks ...

And I'm not talking about the glossy paper used for a lot of advertising (80% I would say) ...

Observe the flame of the paper: if it is green it is chlorine ...

In principle, an incineration plant conforming to European standards traps chlorine in the form of hydrochloric acid.
And if it's not up to standard, well ... we forced it to stop.

I have already approached the issue with the idea of ​​making your own pellets at home.

My observation being that my letterbox is filled with unwanted ads that I pay, through my "household garbage" taxes

We consider a pellet consumption of 15kg / day for a house of 110m². It therefore seems realistic to manage the supply of this free raw material (especially in the city).

I found machines to make pellets in small quantities (20kg / h) for less than 1000 €.

So that seems feasible to me, but we have to take the plunge ...

Another method to heat wood without polluting: put your old paper in the trash instead of recycling it.
Household waste is an increasingly attractive source of energy with increasing petroleum. And what is paper, if not wood!

But we find it normal and very ecological to burn wood when it is in the form of logs or pellets, andsave wood when it's in paper form ... weird, weird ...

Except that we spend much less energy to make paper or cardboard from paper or cardboard than from wood ... So recovering papers to make paper is more ecological and economical than doing paper from wood and energy from paper ...

Hello,

I found machines to make pellets in small quantities (20kg / h) for less than 1000 €.

Do you have links to these machines? I only found bigger ones ... And I think that is the solution to many problems!

Thanks in advance...

There is the model 9PK120, in 220V on the site Pellet blog.
It's Chinese material, I don't know what it's worth.

I regret that the current "against" wood articles speak generically of "wood burning".

I agree with you !

On the Canadian government website there are documents on pollution from wood heating, but they emphasize that recent and efficient appliances are much less polluting than open fireplaces or old stoves.
example:
http://www.santepub-mtl.qc.ca/Environnement/chauffage/pdf/feuillet2009.pdf

I also found a small article that highlights the very big differences between wood heating modes:
In these times of cold winter, we like to be warm at home and what is more comfortable than a good wood fire, moreover, is economical !!

Question of operating cost, wood leaves everyone on the floor, it is the cheapest energy after the sun which is free (unfair competition therefore).

With this its use has improved sharply with the appearance on the market of automatic boilers fed either by wood chips or by wood pellets. Today it is as practical to use as a good old fuel oil boiler, you fill up, you control your thermostat at the desired temperature and roll my chicken, no more loading worries, it's clean, efficient.

And with a carbon neutral balance, because the co2 (carbon dioxide) released into the atmosphere by the combustion of wood is again captured by the young tree that we planted to replace the one that we cut. According to AGEDEN, a tree fixes a ton of CO2 per m3 of wood produced, it is not nothing.

The problem is pollution. Not CO2 (carbon dioxide), but what remains: tar, acids, dust, Hydrocarbons (PAH) and Co (carbon monoxide).

More precisely, it is PAHs (polyclinic aromatic hydrocarbons) and dust that are pointed out.

So who (what) emits these little crap not good for health especially at the moment we do not have a bit of wind to chase it all?

Industry, transport, agriculture AND (it must be recognized) the combustion of firewood.

So should you throw your wood stove over the top?

Well no, because it all depends on the quality of your heating point.

For wood PAH alone, which accounts for 33% of national emissions, nine-tenths are attributable to older generation devices.
out of the 6 million homes heated with wood,
27% are by open chimneys,
45% by inserts,
13% by stoves,
9% by cookers
and only 6% by boilers of which a tiny part in automatic boilers with wood chips or pellets. (source AGEDEN)

For the emission of fine particles same diagnosis:

The use of a modern insert makes it possible to reduce polluting emissions by 7 to 30 times compared to an open hearth.

Automatic boilers generate up to 80 times less pollutants compared to older generation stoves and stoves.

In short, an open hearth (the pretty fireplace where the wood crackles) emits 100 times more fine particles than an efficient stove and the figure increases even more when compared with a pellet boiler.

The quality of the wood used and the way in which the heater is used are also at issue. When you burn wet wood, you increase particle emissions by 2 to 4, and the more you run it at idle, the more it pollutes (you multiply particle emissions by 6 or 7).

In summary, recent heaters that burn dry wood (when burning wet wood increases particle emissions by 2 to 4) to the standards announced by the manufacturer (not at least) is a device that will emit little pollutant .

So where is the problem ?

The problem is that the rise in the price of energy (gas or oil) has brought out of the cupboards the old wood stoves of grandma and rekindled the fireplaces which pollute the better.

So the best (again!) Is to abandon the old wood stove at the recycling center (or keep it for decoration) and equip yourself with an efficient stove (green flame) or a recent wood boiler which comply with the standards in force and which will limit pollutant emissions

It should be remembered that greenhouse gas emissions can be reduced by up to 60 times between the use of wood energy and the use of fuel oil, which therefore uses wood energy to have a very significant impact. on climate change

So let's not throw the baby out with the bath water.

Well, for once an article not bad at all!

It makes the distinction "neutral in CO²" and other emissions (otherwise systematically obscured).

And "modern devices" / old cuckoos!

I would only add two points:

1) The Green Flame, for me, is a kind of self-label that is far too loose. For me, is worth nothing (or not much).

2 ° Whatever the system, the interest of having devices which "work" thoroughly. Regulation by "suffocation" ("draft"), is from the point of view of pollution, dramatic. So that of buffer stocks and / or microprocessor controlled boilers. Or mass storage (mass stove).

Hello,

There is the model 9PK120, in 220V on the site Pellet blog.
It's Chinese material, I don't know what it's worth.

Interesting, the price is starting to be interesting, just make 5 tonnes from wood, grass or homemade manure for it to be amortized, except the electricity of the engine ...

Anyone have experience with these materials?

[bernardd]

Hello,

Thanks to Nutt for the Ageden document, it seems very clear and fair.

The release of NoX or dioxin does not come from wood but from the combustion of any carbonaceous material at too high a temperature.

2 ° Whatever the system, the interest of having devices which "work" thoroughly. Regulation by "suffocation" ("draft"), is from the point of view of pollution, dramatic. So that of buffer stocks and / or microprocessor controlled boilers. Or mass storage (mass stove).

Or precisely pellet stoves, because they regulate combustion by the quantity of pellets supplied, which keeps their combustion at the best speed.

It only lacks a complete recovery of the heat of the combustion gases, which by the condensation of water vapor would allow to increase the output as for the other condensing boilers, would allow to heat a double flow ventilation for example, and would allow to justify complete filtering at the outlet, as for a vacuum cleaner.

Hello,

This is a very interesting thread ... And especially the post to nutt.

For those who still doubt the extreme quality of pellet manufacturing, and the respect of the manufacturing process with respect to ecology, here is an interesting link: www.enerbois.ch
It's a state-of-the-art "factory", but there are plenty of others like that ...
