Hardwood Briquettes

[Stereo]

For one thing it can't be good for the flue. No idea on the health risk but I doubt it's good news over time. I've got mates who seek out the pallets with the chipboard blocks as they burn so well.

I was more than a bit surprised to read this on the DEFRA site:

 

Combustion of MDF could fall within the scope of the Waste Incineration Directive (2000/76/EC) or "WID" but, Defra guidance (under the environmental permitting regulations for England & Wales) is that the MDF manufacturing process does not use chemicals containing halogens or heavy metals so, provided clean waste wood was used to manufacture the MDF, WID does not apply to MDF combustion.

 

Note that combustion of faced MDF could be a WID activity because, although the resin used in such facings is very similar to the urea-formaldehyde resin used in the board, the facings often contain other materials (paper, plastics).

 

I've always told people they shouldn't be burning this stuff in their stoves - and I still don't think I'd want it in mine in spite of the above.

 

The quoted stuff above is from the commercial and industrial section of the DEFRA site. There is a link on the page to a waste wood document, but the page it points to is missing. I've not seen any info on using it in a domestic setting on the DEFRA site.

Kent? Where? Who?

 

I have been looking for a local (Kent) supplier of hardwood briquettes, but without success.

 

Generally buy pallets of 400kg to 1000kg, dependant upon supplier.

 

Liverpool Wood Pellets have one of the better products, burns hot with lots of after-glow, they claim around 5.5kWh/kg. Ash content is rather high for hardwood product, but no sawdust residue as with many of the wood-based briquettes.

Are these imported from Eastern Europe mate?

Hi Andy

 

Yes these are imported. We are part of a worldwide timber trading company, and the briquettes are from the waste residue used in their mills in Eastern Europe.

 

We stock Birch and Alder briquettes, Pine Pellets as well as the Hardwood Briquettes

hardwood briquettes are better. it contains more heat value, less smoke.

Here is a roller type briquetting press manufacturer from China.

 

Actually as softwoods tend to have more lignin they contain more energy by weight. Also the presses you link to seem to be pillow presses used to make briquettes from powders with a binder, typically used for coal dust, e'g. phurnacite. rather than extruded at pressure to make the lignin flow and cool to bind the particles.

One particular mixed briquette I am currently burning requires the stove ash pan to be emptied each and every morning, another (hardwood) briquette I trialled a couple of days ago produced almost no ash at all.

 

All stove manufacturers recommend that the ash in a multifuel stove is emptied on at least a daily basis. Of course this is not the case on a dedicated wood burner where you are burning on the floor of the firebox.

 

As John said 70bar is the recommended pressure for extruding wood, however there are many briquettes in the market which are formed on plastics extruding machinery, these are only able to go up to 25bar hence crumbling less dense products.

A mate of mine has one of these machines and is doing very well using all of his sawdust and shavings from his carpentry business, only snag is that he now cannot get enough sawdust etc to keep up with demand! Anyone buy the raw material in? Not viable?
