Raw material

The term biomass generally really applies to a fuel source rather than a specific generation technology. Biomass fuels are combustible organic materials which can vary dramatically in form. For example, agricultural by products such as wood chips, almond shell, and municipal solid waste are examples of materials which could be combusted with little processing to generate electricity. Cogeneration can utilize biomass fuels, or the material may be combusted directly in a boiler.

Biomass as a fuel source also includes "biogas' fuels. For example, methane recovered from landfills can be combusted to produce electricity. This technology reduces fugitive methane releases (a major greenhouse gas) and produces a useful commodity. Another source of biogas are farms; dairy waste products (manure and other material) can be placed into a "digester" where microbacterial decomposition produces combustible gases. This technique can also be applied at waste water treatment facilities.

Mechanical durability simply refers to how dense the pellet is, and how well it is formed. Pellets that are denser are of course stronger, the advantage is the pellets withstand transportation better, and work more efficiently in the pellet burner.
When a quality pellet has exited the pellet press, it should have a smooth surface, with little or no cracks. If the pellet is cracking and expanding it is because there is too much moisture within the pellet, or poor compression within the pellet press. Once a quality pellet has cooled, it should be like a coloring crayon. The surface of the pellet should be smooth, and have a surface shine.

Wood pellets tend to shine more than others; the most important thing is the pellets smooth compact state. Try tapping the pellet against a hard surface, to see if the pellet stays intact, or if they crumble or easily crush and separate. The length of the pellet is not really that important. However if pellets are too long (above 1 inch) they can cause damage to the auger in the pellet burner.

Pellet making process

Many people today are now using wood pellets and biomass pellets as their source of heat for their homes, this has lead to an increase of interest in actually how wood and other biomass pellets are made. The main piece of equipment used is referred to as a pellet mill, though it may also be called a pellet machine or pellet press. A pellet mill is a industrial piece of equipment, even small pellet mills have to be built to a high standard to cope with the stresses of forming a pellet. However, this also means that generally speaking, a pellet mill is also not a cheap piece of equipment, leading to some looking for ways for them to build their own pellet mill.

So how realistic is it for people to build their own pellet mill? Well, technically you could make your own pellet mill, the problem is to make a pellet mill of sufficient quality due to the components required would probably cost you more than purchasing one. This may lead you to believe that owning and operating your own pellet mill is not for you due to the costs involved. Well, first you need to look at the cost of the pellet mills you have been looking at, as many of them are probably Chinese imports which have been marked up with huge profit margins. Therefore if you can find the source of the pellet mills, you can literally save your self thousands of dollars on the cost of a pellet mill. However, some of the Chinese pellet mills are animal feed pellet mills miss-sold by re-sellers as wood pellet mills. You need to avoid these pellet mills, and choose units which are specifically designed to process wood and biomass materials.
