Wood working causes serious loss of wood. At the stage of logging, the amount that goes in to waste n in the form of needles, boughs and stubs may be 40% of the original piece of wood. Studies show that a saw mill turns in to plank only 60% of the wood. The remaining 40% is wasted through hungry wood (6%), sawdust (12%), and haggs and slubs (22%). The sources of pellet raw material include rind, sawdust, roundwood, slab, shavings, and wastes from the processing of timber. (more…)
Generally speaking, all the pellet fuels are sourced from biomass materials – the products of plants and trees that are commonly grown. The most popular residential pellets are products of ground wood chips and sawdust – the waste from trees during the making of lumber, furniture and other products. The lignin and resins that naturally occur in sawdust hold together wood pellets and they do not contain any additives. (more…)
Wood pellet technology is one of the latest innovations that are aimed at saving the natural beauty of the earth. It started in the United States in 1970s in response to the then Arab oil embargo. The technology has managed to discover new source of environment friendly renewable energy in biomass pellets. The technology has proved that wood is not the only alternative to biomass. The wood pellet technology is aimed at providing new and sustainable non-food biomass source that is focused on provision of energy in an environment friendly, sound and abundant environment that has no political controversy.
Biomass pellet fuel is made from biomass that is compressed. The most common type of pellet fuel is wood fuel. As one of the wood fuel forms, wood pellets are made from sawdust that is compacted. In the pellet mill, other sawmilling wastes can also be used in the manufacture of wood pellet. Other sources of woody biomass include coconut shell, palm kernel shell, grass, etc. Whenever you want to purchase biomass pellet fuel, it is highly recommended that you put in to special; consideration the following factors.
Because of the increasing of popularity of pellet fuel, many people want to know how to make biomass waste in to pellets. Well, the process of fuel pellets manufacture involves the placing under high pressure ground biomass and then forcing it through round opening that is referred to as die. When it is exposed to the suitable conditions, the biomass will fuse together to form solid mass. This process is referred to as extrusion. Some of the biomass especially wood has the natural capability of forming fuel pellets of high quality. (more…)
Biomass pellet fuel is a not only environmental friendly but also economical. It is a high quality, renewable, solid biofuel. Unlike the traditional biomass fuels such as pruning and logs which are mainly characterized by drawbacks such as high content of moisture and low density of energy, the biomass pellet fuel is capable of effectively combining significant properties such as low content of moisture, high energy density, and homogeneity in shape and size. The parameter of homogeneity in shape and size is especially important when considering issues such as transportation and storage.
Biomass pellets for industrial use are made through the compression of wood shreds or sawdust. The compression is done under high pressure so as to ensure that lignin softens such that it can now bind together the material. The combination of the low content of moisture and material that is highly compressed leads to the production of high volume energy density that is 3 to 4 times as compared to wood chips. The biomass pellets are not only consistent and clean but they also flow very easily. These features make them especially attractive for industrial use. The considerably lower requirements of storage as compared with wood chips make them highly attractive to the urban applications e.g. schools.
Pellet fuel is the ideal fuel for the 21st century. This is so because the burning of fossil fuel leads to the emission of carbon dioxide that causes serious damage to the environment. On the other hand, the pellet fuel is carbon neutral. The term carbon fuel means that the tree absorbs the same amount of carbon that it will give off when it is burnt and thus there will be no addition in to the amount of carbons dioxide in the atmosphere. Wood pellets and wood are solar energy in stored form.
