Biomass is a very general term to a wide selection of potential energy sources. Wood can be purpose grown fuel source or a waste, or currently perceived waste. When biomass is referenced, in many cases the reference is still to do with wood. Timber has been used for fuel manufacture for thousands of years, as well as does and will continue to play a central role in wood energy and biomass combustion. On the other hand, woody wood is only on small part of the picture, potentially all grasses, straws, fuel crops in addition to even animal waste is a probable source of energy owing to biomass incineration. The key issue by all of these raw materials is how do you use them. All of these resources have a different shape, size, density in addition to moisture content. To manufacture a wood combustion solution which can use all these possible fuel sources would be extremely difficult, fee plus not a very practical exercise. Also transporting these low density as well as high moisture content materials is also not very practical or charge effective. Some of these biomass materials will have a moisture content as high as 50%. So in essence transporting this material means half of the haulage costs are spent on moving water. When biomass is promoted as a green energy by means of low carbon emissions, unnecessary transport is the biggest drawback to wood energy resources.

Therefore what is answer? Well, in many cases processing the biomass into pellets for biomass combustion is the most practical as well as affordable solution. A pellet is a highly compressed form of the wood material into a uniform size in addition to shape with a moisture content below 10%. This gives the wood completely different burning characteristics, plus means that many different types of wood resources can be used in one system designed to burn pellets. At present the biomass pellet fuel market is dominated by means of biomass pellets, and not only wood pellets but premium biomass pellets. This was to generate a pellet energy which shaped the least ash content probable to try along with compete by way of oil plus gas systems in terms of maintenance. The resources used to make premium fuel pellets are definitely a valid energy source, they cannot meet the future probable pellet energy market demands. Therefore more different grades of wood along with extra wood energy pellets will grown in demand.

Wood incineration ideas have been traditionally basic log stoves, on the other hand pellets bring all new possibilities. Pellet burners can automatically feed pellets into the fire, along with even ignite the fire on demand controlled through a standard wall thermostat. A full pellet burner hopper can last for several days, and by way of a large ash draw the combustion unit may only require attention once a week to clean out the ashes. The process of making pellets is subject many people are interested in, however there is very little detailed information accessible on the facts plus details on pellet manufacture. The central piece of equipment in pellet plant is the pellet mill. Yet there are quite a few unlike designs of pellet mill, in addition to not all are suitable for each raw material, and may need modification.
