Wood is a general term used to describe any organic based material which can be used as a fuel source. Oil and gas are manufactured from natural based life forms from thousands of years ago, and are not component of the current carbon cycle, they are therefore not regarded as biomass. One of the most common materials used for biomass energy today is biomass as well as waste wood resources. For instance is developing countries wood is still heavily used as the main source of energy to cook food plus boil water.

One of the most practical as well as efficient ways to convert woody biomass into an efficient fuel source, is to upgrade the biomass into pellets, to be used in a wood pellet boiler. A wood pellet is a highly compressed form of wood, which contains very little water. The wood pellet boiler automatically feeds the pellets from a hopper into the burn pot. At present the pellet fuel along with pellet boiler market are dominated by means of wood pellets, however there are many other forms of biomass which can be used. For case, here at PelHeat we have a wood boiler which burns a mixture of pellet fuels. Currently we burn a majority wheat grass pellets. Wheat straw pellets contain almost the same amount of energy as wood pellets, however are much cheaper to manufacture. The reason wheat grass pellets are cheaper to manufacture, is because the raw material is still regarded as an inconvenience. Also it takes much less fuel to compress wheat straw into pellets, compared to wood. The disadvantage with wheat grass pellets is the increased amount of ash that is formed. Grass pellets also create an ash which melts at a lower temperature. Melting ash turns into a hard clinker formation once cooled. We specifically purchased our wood boiler by a burn pot and auger designs which could remove the clinker away from the combustion zone. Yet most pellet stoves in addition to pellet boilers cannot deal by clinker formations.

Owing to our research of how dissimilar wood pellets burn, in addition to the knowledge that we gathered we have complied into a guide called the pellet stove in addition to boiler guide. The various features which are more crucial for efficient combustion. These include burn pot designs, auger feed mechanisms in addition to many other features. At PelHeat we also research and develop pellet manufacture solutions. There are a mixture of pieces of pellet equipment used to create biomass in addition to wood pellets. On the other hand before a pellet can be shaped, the raw matter must be dried to around 15% moisture. Virgin wood resources usually contain around 50% moisture, so drying is commonly required. Though many other wood materials including many straws, grasses and fuel crops can be harvested at the correct moisture content. As these resources do not require drying, the fuel used to produce the pellets is much less. This way that they are not only cheaper to make, they are also better for the environment, developing a lower carbon footprint. Once the matter has been dried, it is now ready for pellet compression. This usually takes place in the pellet mill, also known as a pellet press or pellet machine. After compression strong durable pellets are shaped to be used in the biomass boiler.
