Biomass is a general term used to describe any untreated based matter which can be used as a fuel source. Oil in addition to gas are made from natural based life forms from thousands of years ago, along with are not part of the current carbon cycle, they are therefore not regarded as wood.
One of the most common materials used for wood fuel today is wood along with waste wood resources. For instance is developing countries biomass is still heavily used as the main source of fuel to cook food and boil water, learn more about Pellets
One of the most practical in addition to efficient ways to convert woody biomass into an efficient energy source, is to upgrade the wood into pellets, to be used in a biomass 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 this time the pellet fuel plus pellet boiler market are dominated by biomass pellets, however there are many other forms of wood which can be used. For case, here at PelHeat we have a wood boiler which burns a range of pellet fuels. Currently we burn a majority wheat straw pellets. Wheat grass pellets contain almost the same amount of energy as biomass pellets, though are much cheaper to manufacture.
The reason wheat grass pellets are cheaper to make, is because the raw matter is still regarded as an inconvenience. Also it takes much less fuel to compress wheat grass into pellets, compared to wood. The disadvantage with wheat straw pellets is the increased amount of ash that is produced. Straw pellets also create an ash which melts at a lower heat. Melting ash turns into a hard clinker formation once cooled. We specifically purchased our wood boiler with a burn pot and auger designs which could remove the clinker away from the combustion zone. Though most pellet stoves as well as pellet boilers cannot deal by way of clinker formations, read more about Biomass Boilers
Owing to our research of how dissimilar biomass pellets burn, along with the knowledge that we gathered we have complied into a guide called the pellet stove plus boiler guide. The various features which are more crucial for efficient combustion. These include burn pot designs, auger feed mechanisms and many other features.
PelHeat we also research as well as develop pellet construction solutions. There are a range of pieces of pellet equipment used to manufacture biomass plus biomass pellets. On the other hand before a pellet can be formed, the raw material must be dried to around 15% moisture.
Virgin wood resources usually contain around 50% moisture, so drying is commonly required. Though many other biomass materials including many straws, grasses plus energy crops can be harvested at the correct moisture content. As these resources do not need drying, the energy used to make the pellets is much less.
This technique that they are not only cheaper to produce, they are also better for the ecosystem, 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 machinery. After compression strong durable pellets are created to be used in the biomass boiler.
