Briquettes plywood dust

Today, almost 80% of plywood enterprises of Russia recycle their production and have installations for the production of briquettes. Fuel briquettes used in domestic solid fuel boilers, fireplaces, furnaces, and industrial boilers.

How it all began
Production technology of fuel briquettes came to Russia more than ten years ago with IKEA. Opening a enterprise, IKEA through its technology installed Briqueterie press, and then our producers were able to personally sure that the waste that typically have a negative cost, it is possible to earn good money.

Since then, the problem of waste disposal has been widely discussed in the business environment and promoted in the media. As a result, today, many wood processing plants are thinking not about how to get rid of waste products, and about what kind of biofuels (briquettes, pellets, etc.) to produce, looking for the most economical option.

Briquettes from dust
For companies producing plywood, one important issue is the disposal of the sanding dust. It has its own peculiarities. The fact that the raw material for the production of woody biofuels always presented two main requirements. The first requirement is a certain level of humidity, which should be no higher than 14%. If the humidity is above that figure, the process of briquetting, which occurs under high pressure is technically difficult to carry out, since moisture, as we know, is not compressed. The second requirement is the corresponding fraction from which made briquettes. Technology under pressure of up to 1700 kg/cm2 is the destruction of the cell biomass, the lignin is released and is a link, so the briquette is an environmentally friendly biofuel

In a plywood dust, the cell which has already been dried and destroyed, lignin is small, moreover, the Russian plywood made mostly of birch, this tree species has a low lignin content, so raw materials requires extra hydration and sometimes adding a small amount of lignin or starch powder.

No problems with selling
Sales of fuel briquettes from plywood dust is quite successful. This is understandable: all fuel briquettes from wood, including plywood is made of dust, are the product of a profitable and convenient for the consumer. First, wood fuel briquettes have high calorific value, with a calorie do not depend neither on fraction, nor on the form of briquettes. Impact on calorie and has only a wood species from which made briquettes and the briquette density. Calorific value of briquettes is typically in the range 4 100 - 4 700 Gcal per hour, is slightly less than the calorie of coal, but significantly higher than in normal wood (one cubic metre of briquettes replaces the caloric content of three cubic meters of firewood). The second important consumer feature – minor amount of ash formed during combustion of the biofuel. So, if after burning coal to produce 20% ash, the same indicator for the briquettes does not exceed 0.12%.
