Sweden is one of the globe’s biggest wood pellet fuel producer and also consumer. It’s wood pellet manufacturing modern technology, industry plan, as well as market design are prominent. In richi pellet machine , I will do comprehensive analysis on Sweden biomass pellet fuel sector, as well as work out some valuable experiences.
Introduction
In the 1970s, many countries have made policies to advertise biomass power as a means to deal with energy crisis as well as environment contamination. Since then, biomass power sector has established quickly, and the innovation keep boosting.
Because of the lack of mineral resources, Sweden’s economy experienced terrific loss in last century. To ensure nationwide energy security, Sweden government make every effort to create renewable resource.
Biomass pellet fuel has the attributes of high burning performance, low ash content, no carbon discharge, simple transportation, which has been prominent in Europe and North America. With abundant forestry resources, Sweden pay much focus to the development of biomass pellet fuel. Sweden takes up 20% of the globe’s biomass fuel intake, which grows up at the speed of 8-10%.
Sweden forestry sources and biomass products
Sweden has abundant forestry sources. The forest covers 64% of the acreage, with 51% owned by individuals, 24% by huge wood firms, and 25% by nations as well as other public companies. Besides, the forestry grows by 100 million tons yearly, and also the logging quantity is 92.4 million lots. The major forestry industries are wood processing, paper processing, and also power wood. The wood products for making biomass power primarily come from the 3 sectors above, concerning 23.48 m3.
Basic material of wood pellets
Of the raw products for making wood pellets, wood shavings take up 53%, sawdust 35%, as well as wood chips 5%, others (barks, agriculture residues, energy forestry) takes up 7%. Some small wood pellet factory are built base upon chipboard, furnishings and sawdust mills.
With more companies participating in biomass fuel production, the competitors on the raw products end up being much more tough. As the crop straws in Sweden are in scattered distribution, they are hard to accumulate as well as process. So some producers and also institutes are developing brand-new products like peat and energy plants.
Wood pellet making modern technology and equipment
The pellet molding technology has actually grown in Sweden. Nowadays, it has actually accomplished business and market production. The manufacturing process includes high automation, needing less operators. The picture below displayed the wood pellet manufacturing process.
Drying: usually, the wetness material of sawdust is around 50%. A drum dryer can reduce the moisture web content to 9-12% to ensure that it is received making pellets.
Crushing: the size of resources should be under 5mm. They require a hammer mill to reduce the dimension.
Conditioning: add high-heat vapor to the raw materials and also soften the cellulous in it. Over half of the pellet fuel manufacturers have conditioning process in production.
Pellet molding: most wood pellet manufacturing facilities use upright kind ring pass away pellet equipment. The manufacturing capability of one maker 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 problem are simple to damage as well as inconvenient for transportation. A counter-flow colder can cool off the wood pellets in a modest way.
Packaging: the cooled down pellets require to be categorized and packaged according to customers’ need. Tiny bags are 16kg, large bags are 900kg. For big consumers like nuclear power plant, the wood pellets are transported by trucks and also ships in bulks.
Biomass pellets category and application
In 1999, Sweden government published the criterion of wood pellet fuel, in which they are categorized right into 3 courses. The first-rate has top quality. They can be made use of in residential tiny heaters and also stoves.The second as well as third do not have excellent quality. They are utilized by big industrial clients.
Presently, 57% of the wood pellet fuels in Sweden can fulfill this requirement. A few of them can meet the EU requirement, others are not produced according to this requirement.
Wood pellet fuel can be used in small boilers, medium-scale and massive home heating supply facility and nuclear power plant. Presently, Sweden has 60% of wood pellet fuel for tiny as well as average home heating boilers as well as local home heating supply facility, and also 40% for large home heating supply center and also co-firing nuclear power plant.
From the 1970s to the 1990s, Sweden regional heating plant take on coal to change oil. After the enact of CO2 emission tax, these heating plant resort to biomass fuel from coal. In the last decade, the amount of biomass fuel for heating grows from 1.1 PJ to 57PJ. Currently, regarding 400 regional heating plant has actually embraced wood pellet fuel.
Considering that the mid 1990s, domestic wood pellet industry has actually made great progression. In the last years, the use of domestic heating wood pellets proliferates. Presently, Sweden has 200,000 family members making use of wood pellet central heating boilers, 40,000 family members utilizing wood pellet cooktops.
Sweden biomass power advancement goal as well as plan
To promote the continuous advancement of biomass power, Sweden has actually made a collection of regulations and also plans. To make sure the carry out of these policies, the federal government likewise made many practical supervision actions and compulsory market requirement.
Sweden not only satisfy the commitment specified Kyoto Method that reduced greenhouse emission by 8%, yet likewise set its own advancement goal of biomass power. In 2006, the Priest for lasting development department claimed that Sweden will totally utilize biofuels as well as stop utilizing oil, and come to be the initial nation that completely rely on renewable energy.
By 2020, Sweden will certainly raise its percentage of renewable energy to 50%, the use proportion of renewable resource in transportation market to 10%, energy performance by 20%, as well as cut the exhaust of greenhouse gas by 40%.
Wood pellet fuel motivation policy
Sweden has actually carried out high price procurement, investment aids, tax decrease and exemption, quota system and also various other biomass power motivation policy.
Considering that 1975, Sweden spends 36 million Euro from federal government budget to support biomass innovation growth. From 1997 to 2002, the government provided 25% financial investment aid to biomass cogeneration projects. From 2004-2006, the government supplied 1350 Euros for homeowners who use biomass furnace.
Sweden normally lay high tax obligation on fuels, energies, CO2, SO2, etc. To advertise the advancement of biomass power, to excuse all taxes on biomass projects. In 1991, Sweden federal government begins to lay tax on carbon dioxide exhaust, that makes the rate of oil as well as nonrenewable fuel source surge. A lot of warmth supply center and power plants switches over from nonrenewable fuel source to biomass fuel.
To encourage the power plant to use biomass energy, Sweden government introduced electric power quota system. This plan calls for the power vendors to have specific portion of electrical power created by renewable resource. For each 1MWh electricity, the government will certainly offer tax relief based on the biomass power quantity.
Sweden wood pellet fuel shedding device
Sweden wood pellet burning modern technology remains in the leading placement. There have actually been over 20 pellet burner manufacturers, over 50 sorts of wood pellet central heating boilers, 120,000 collections of pellet boilers, 20,000 sets of pellet cooktops. As there are still lots of family members making use of electric heating, the pellet boilers have big possibility.
Sweden pellet burning tools has main heating central heating boiler and also biomass range 2 types.
Central home heating central heating boiler can be used in 1 or even more families. The thermal transmit with water. The powers are 10-40kw, which can be readjusted by 30% -100% according to requirements. The main heating boilers likewise has 2 types. The combined boiler is linked by a pellet heater as well as a common boiler. The boiler can connect with numerous heaters. The integrated boilers are generally imported from Austria and also Germany, some created by residential manufacturers.
Biomass cooktops or heating system
Biomass stoves additionally has 2 kinds. Independent pellet oven as well as Chimney item type furnace. The former on is more preferred. The independent pellet cooktop has a pellet supply bin inside, which can hold wood pellets for 2-day use.
Biomass pellet oven can realize automatic dental filling as well as burning. Based on different feeding approach, pellet stoves has leading feed, bottom feed and horizontal feed 3 kinds. Leading feed pellet ovens are the most popular. Owing to high ease as well as cleanliness, tiny pellet ranges market well over the last few years.
Attributes of Sweden biomass fuel market
Sweden has rich forestry resources and also abundant forestry waste, which come to be the primary resources for biomass pellets.
Sweden wood pellet market has actually been fully commercialized. The majority of producers are large and average companies, with mature innovation. Little wood pellet manufacturing facilities are primarily build on chipboard, furnishings and also saw mills.
The government has actually made extensive regulations as well as plans to drive the wood pellet manufacturing. This is why the wood pellet market creates swiftly since the 1990s.
Requirement for wood pellet fuel maintain enhancing. In the 1990s, Sweden released the criterion for wood pellets, and also gauged the method date of pellet fuel and also burners.
Mature burning modern technology and tools. Recently, Sweden’s manufacturing of pellet central heating boiler and also pellet home heating ovens keep boosting.
Perfect quality control system. Sweden federal government stated that the wood pellet fuel as well as burning devices should get third-party testing certifications prior to getting in the market.
Verdict
