Money for old rope...

[Ty Korrigan]

And so...

We have a free ad's web site here called 'Le Bon Coin' which translates as 'the good corner'

I have a paid advert on this site which costs so little it is embarrassing to use a credit card for payment.

The advert is for our wood chips.

I offer conifer, old matured mix, clean winter hardwood or general hardwood with leaves, whatever is in stock at the time.

People can either come to the yard and load up their choice for as little as 15 euros per m3 or we can deliver a minimum of 3m cube

The image below is 8mcube which I will deliver on a Sunday afternoon for 180euros or £140 sterling pound notes.

Mulching here is very much the fashion in gardens and as many gardens are far larger then the ones in the U.K people are always looking for a means to avoid weeding their beds.

There is a strong move away from geo-textiles (terrum?) and herbicides to suppress weeds and as a result our wood chip pile is at an all time low K'ching!

Hope to have found a new home for my chip if I get the new yard next month, local company has a big biomass drying plant so will take it by the container load, dry it to about 28% and run the 1mega what boiler s on it blended with g50 chip.

Probably also get a pile of very leafy stuff going for mulch.

0% waste = maximum profit or that's the theory anyhow.

We are also hoping that the new power station for producing hot water to heat municipal buildings and tower blocks in Rennes will change their specification for wood chips to allow smaller grade to be used.

There are biomass companies around here contracted to supply a certain amount of wood chip per year but there simply is not enough conifer or poplar available long term without widening the spec to include other green waste.

When that day arrives, we may never need again visit the local tip!

I see all the communes with large chip on the flower beds but never the smaller greenmech type chip. I must be missing out big time.

Hi Ty,

 

Thats really good, Id have some myself but you're a bit too far away,

 

If you end up supplying CHP then it'll disappear even faster

Still looking round before changing heating system

There seem to be domestic boilers that run on chip, am I (we?) missing a trick here?

 

Also talking to someone who imports finshed wood products fom Poland

They had to fill in some green forms for a major retailer

Polish supplier told them Polsh workers take sawdust home to run their central heating

 

Again another market

The chip needs to be of a particular & uniform size for the boiler; and has to be within a moisture range. The feed for chip boilers tends to be auger driven, in which case, the size is most important for a given feed volume. The moisture is also important. Too moist and the boiler is wasting energy drying the fuel instead of producing the optimum heat output. Too wet and it can jam up the auger, as it sticks to surfaces, plus it can build up creosote layering on internals. Which could be problematic and expensive to clear.

 

From what i gather, too dry produces too much dust for optimal stated thermal output, as it get moved/grinds around in the hopper.

 

I suspect sawdust would have to conform to the same moisture content for roughly the same reasons. On a small scale, both chip and sawdust could be dried without specialist equipment. But for more than just the occasional use, it would require extra pre-processing in either a dryer or more expensive, (and larger) boiler, which can help pre dry the fuel before it enters the hopper.

 

For the smaller boiler that only heat the hot water and are gravity fed. I could see that you'd not need that much space, to dry the chip/saw on multiple flat surfaces. But you'd still have the carefully monitor the moisture content, for the same given reasoning.

Edited last paragraph

Too many typos in the last paragraph and I'd run out of time for an edit.

VTS, try Le Bon Coin, never know...

Also, communes won't pay you for it, they want and get it for free.

Waiting for the client to arrive...

Bloke I deal with dries it by the container load, had a 400kw 'i think' boiler heating water that go's into a heat exchange hot air blower and can cope with 4 containers of green woodchip and dry it to >25% moisture in 48hrs, can't hold your hand infront of the blower it's so hot.

Now experimenting with arb chip with leaf in it as supplied 2 1mega Wat boilers that can cope with hog wast through the feed system but don't like v dry stuff like processed pallets.

Shame I don't know any1 with a small grader as separating the mulcher into fine conditioner grade, woodchip and oversized rubbish would make whole lot more marketable.

I know what your saying about the smaller systems being more fussy both with fines and oversized hence why they get air dried g30 chip only.
