With abundant forestry resources, Sweden pay much attention to the growth of biomass pellet fuel. Sweden occupies 20% of the globe’s biomass fuel usage, which grows up at the speed of 8-10%.
Sweden forestry resources as well as biomass materials
Sweden has bountiful forestry sources. The forest covers 64% of the acreage, with 51% possessed by individuals, 24% by big wood firms, and also 25% by nations and also other public organizations. Besides, the forestry grows by 100 million lots each year, as well as the logging amount is 92.4 million lots. The major forestry sectors are wood handling, paper handling, and energy wood. The wood products for making biomass energy mostly originated from the 3 sectors above, about 23.48 m3.
Raw materials of wood pellets
Of the raw products for making wood pellets, wood shavings use up 53%, sawdust 35%, and wood chips 5%, others (barks, farming residues, energy forestry) uses up 7%. Some tiny wood pellet manufacturing facility are constructed base upon chipboard, furniture and also sawdust mills.
With even more business engaging in biomass fuel production, the competitors on the raw products end up being a lot more fierce. As the plant straws in Sweden are in scattered circulation, they are hard to gather and also refine. So some manufacturers and institutes are establishing brand-new products like peat and also energy crops.
Wood pellet making modern technology and also equipment
The pellet molding innovation has actually grown in Sweden. Nowadays, it has actually attained commercial as well as market production. The manufacturing procedure features high automation, requiring less drivers. The picture listed below presented the wood pellet manufacturing process.
Drying: normally, the moisture web content of sawdust is around 50%. A drum clothes dryer can lower the wetness web content to 9-12% to make sure that it is received making pellets.
Crushing: the dimension of basic materials should be under 5mm. They need a hammer mill to lower the dimension.
Conditioning: add high-heat vapor to the raw materials as well as soften the cellulous in it. Over half of the pellet fuel producers have conditioning procedure in manufacturing.
Pellet molding: many wood pellet factories utilize vertical kind ring die pellet machine. The manufacturing capability of one equipment is 2-4ton/ h. The service life of ring die is 2000-3000h, while the roller can last 1000-1500h.
Air conditioning: the wood pellets extruded out from the pellet machine are at the temperature of 100 ℃. Pellets under this condition are simple to break as well as inconvenient for transportation. A counter-flow colder can cool the wood pellets in a modest method.
Packing: the cooled pellets require to be categorized and also packaged according to consumers’ demand. Small bags are 16kg, huge bags are 900kg. For large clients like nuclear power plant, the wood pellets are moved by trucks as well as ships wholesale.
Biomass pellets category as well as application
In 1999, Sweden government released the requirement of wood pellet fuel, in which they are classified right into 3 classes. The fabulous has excellent quality. They can be made use of in domestic tiny burners and stoves.The second as well as 3rd do not have top quality. They are utilized by large industrial clients.
Currently, 57% of the wood pellet fuels in Sweden can meet this criterion. Several of them can satisfy the EU criterion, others are not created according to this standard.
Wood pellet fuel can be applied in tiny boilers, medium-scale as well as large heating supply facility and power plant. Presently, Sweden has 60% of wood pellet fuel for small as well as medium heating central heating boilers as well as regional heating supply facility, and also 40% for big home heating supply center and also co-firing nuclear power plant.
From the 1970s to the 1990s, Sweden regional heating plant adopt coal to change oil. After the establish of CO2 discharge tax, these heating plant count on biomass fuel from coal. In the last years, the quantity of biomass fuel for home heating grows from 1.1 PJ to 57PJ. Currently, about 400 regional home heating plant has actually taken on wood pellet fuel.
Considering that the mid 1990s, domestic wood pellet market has made wonderful progress. In the last years, the use of domestic heating wood pellets proliferates. Presently, Sweden has 200,000 family members making use of wood pellet boilers, 40,000 family members utilizing wood pellet cooktops.
Sweden biomass energy advancement goal and plan
To promote the constant advancement of biomass energy, Sweden has actually made a series of legislations as well as plans. To guarantee the implement of these policies, the federal government likewise made several feasible guidance actions and compulsory sector standard.
Sweden not just meet the responsibility stipulated Kyoto Protocol that cut greenhouse emission by 8%, but likewise set its own advancement goal of biomass energy. In 2006, the Priest for lasting development division declared that Sweden will totally make use of biofuels as well as stop making use of oil, and also end up being the very first nation that totally depend on renewable energy.
By 2020, Sweden will enhance its proportion of renewable energy to 50%, the use proportion of renewable resource in transportation sector to 10%, power efficiency by 20%, and reduced the exhaust of greenhouse gas by 40%.
Wood pellet fuel incentive policy
Sweden has actually accomplished high rate acquisition, financial investment subsidies, tax decrease and also exemption, quota system as well as various other biomass power incentive plan.
Since 1975, Sweden invests 36 million Euro from federal government spending plan to sustain biomass technology advancement. From 1997 to 2002, the federal government gave 25% financial investment aid to biomass cogeneration jobs. From 2004-2006, the federal government gave 1350 Euros for locals who make use of biomass heating system.
Sweden normally lay high tax obligation on fuels, energies, CARBON DIOXIDE, SO2, and so on. To advertise the development of biomass energy, to spare all tax obligations on biomass tasks. In 1991, Sweden federal government begins to lay tax on CO2 exhaust, that makes the rate of oil as well as nonrenewable fuel source surge. Numerous warmth supply facility as well as power plants switches over from fossil fuel to biomass fuel.
To motivate the nuclear power plant to make use of biomass power, Sweden government introduced electrical power quota system. This plan requires the power suppliers to have specific part of electricity created by renewable resource. For every single 1MWh power, the government will provide tax obligation relief based on the biomass power quantity.
