Sweden biomass pellet fuel sector evaluation<br>
Sweden is just one of the world's biggest wood pellet fuel manufacturer and consumer. It's wood pellet manufacturing technology, market policy, and also market design project. In this passage, I will certainly do comprehensive analysis on Sweden biomass pellet fuel sector, and exercise some useful experiences.



Introduction

In the 1970s, several nations have actually made plans to advertise biomass power as a method to deal with power crisis and atmosphere pollution. Since then, biomass power market has developed swiftly, and also the technology maintain improving.



Due to the absence of mineral resources, Sweden's economic climate endured fantastic loss in last century. To ensure national energy protection, Sweden federal government aim to create renewable energy.



Biomass pellet fuel has the attributes of high burning efficiency, low ash content, absolutely no carbon discharge, very easy transport, which has actually been prominent in Europe as well as The United States And Canada. With plentiful forestry sources, Sweden pay much interest to the growth of biomass pellet fuel. Sweden occupies 20% of the world's biomass fuel intake, which grows up at the rate of 8-10%.



Sweden forestry sources as well as biomass products

Sweden has plentiful forestry resources. The forest covers 64% of the land area, with 51% had by individuals, 24% by big wood business, as well as 25% by countries as well as various other public organizations. Besides, the forestry grows by 100 million bunches each year, as well as the logging amount is 92.4 million bunches. The significant forestry industries are wood processing, paper handling, and power wood. The wood materials for making biomass energy mainly come from the 3 industries above, regarding 23.48 m3.



Basic material of wood pellets

Of the raw products for making wood pellets, wood shavings occupy 53%, sawdust 35%, as well as wood chips 5%, others (barks, agriculture deposits, energy forestry) occupies 7%. Some tiny wood pellet manufacturing facility are built base on chipboard, furniture and also sawdust mills.



With more business taking part in biomass fuel production, the competition on the raw products come to be much more fierce. As the plant straws in Sweden remain in scattered distribution, they are difficult to collect and refine. So some producers and also institutes are developing brand-new products like peat and also energy plants.



Wood pellet making technology and tools

The pellet molding modern technology has actually developed in Sweden. Nowadays, https://richimachinery.doodlekit.com/blog/entry/22204106/using-commercial-wood-pellet-mill has actually attained business and market production. The manufacturing procedure includes high automation, requiring much less drivers. The picture below showed the wood pellet production process.



Drying: normally, the moisture web content of sawdust is around 50%. A drum dryer can decrease the moisture material to 9-12% to ensure that it is received making pellets.

Crushing: the size of basic materials must be under 5mm. They require a hammer mill to minimize the size.

Conditioning: add high-heat vapor to the raw materials and also soften the cellulous in it. Over half of the pellet fuel suppliers have conditioning process in manufacturing.

Pellet molding: most wood pellet manufacturing facilities utilize upright type ring die pellet machine. The production capacity of one machine is 2-4ton/ h. The life span of ring die is 2000-3000h, while the roller can last 1000-1500h.

Air conditioning: the wood pellets extruded out from the pellet equipment go to the temperature level of 100 ℃. Pellets under this problem are very easy to damage and also bothersome for transportation. A counter-flow colder can cool the wood pellets in a moderate way.

Packing: the cooled pellets require to be classified and also packaged according to customers' demand. Small bags are 16kg, big bags are 900kg. For huge consumers like nuclear power plant, the wood pellets are moved by trucks as well as ships in bulks.

Biomass pellets category and also application

In 1999, Sweden federal government released the criterion of wood pellet fuel, in which they are classified into 3 classes. The excellent has top quality. They can be utilized in domestic tiny burners and also stoves.The second and also 3rd do not have top quality. They are utilized by big industrial consumers.



Currently, 57% of the wood pellet fuels in Sweden can satisfy this criterion. A few of them can meet the EU criterion, others are not created according to this standard.



Wood pellet fuel can be used in small boilers, medium-scale as well as massive home heating supply center and power plant. Currently, Sweden has 60% of wood pellet fuel for tiny and also average home heating central heating boilers and also regional heating supply center, and also 40% for huge heating supply facility and also co-firing power plant.



From the 1970s to the 1990s, Sweden regional heating plant embrace coal to replace oil. After the establish of CO2 exhaust tax obligation, these home heating plant turn to biomass fuel from coal. In the last years, the amount of biomass fuel for home heating expands from 1.1 PJ to 57PJ. Presently, about 400 regional heating plant has actually embraced wood pellet fuel.




Considering that the mid 1990s, residential wood pellet sector has actually made fantastic progression. In the last years, making use of domestic home heating wood pellets proliferates. Presently, Sweden has 200,000 households making use of wood pellet boilers, 40,000 households using wood pellet stoves.



Sweden biomass energy advancement objective and also policy

To advertise the continual development of biomass energy, Sweden has made a collection of legislations and also policies. To guarantee the apply of these plans, the federal government additionally made lots of practical guidance actions and required industry standard.



Sweden not just fulfill the commitment specified Kyoto Protocol that cut greenhouse discharge by 8%, however also set its own advancement goal of biomass power. In 2006, the Priest for sustainable development department claimed that Sweden will completely use biofuels and also stop using oil, and end up being the very first country that totally count on renewable resource.




By 2020, Sweden will certainly enhance its percentage of renewable energy to 50%, the use ratio of renewable energy in transportation sector to 10%, power efficiency by 20%, and reduced the exhaust of greenhouse gas by 40%.



Wood pellet fuel incentive plan

Sweden has accomplished high rate procurement, investment aids, tax reduction and also exception, quota system and various other biomass energy incentive plan.



Because 1975, Sweden invests 36 million Euro from government budget to sustain biomass modern technology advancement. From 1997 to 2002, the federal government gave 25% investment aid to biomass cogeneration tasks. From 2004-2006, the federal government supplied 1350 Euros for homeowners who use biomass heating unit.



Sweden usually lay high tax obligation on fuels, powers, CARBON DIOXIDE, SO2, and so on. To advertise the growth of biomass energy, to spare all taxes on biomass projects. In wood pellet maker diy , Sweden federal government starts to lay tax obligation on CO2 discharge, that makes the cost of oil as well as nonrenewable fuel source rise. Numerous heat supply center and also nuclear power plant changes from nonrenewable fuel source to biomass fuel.



To motivate the power plant to use biomass power, Sweden federal government introduced electrical power quota system. This policy calls for the power vendors to have particular section of electrical power generated by renewable energy. For every single 1MWh power, the government will give tax alleviation based on the biomass power amount.



Sweden wood pellet fuel melting device

Sweden wood pellet melting modern technology remains in the leading position. There have actually been over 20 pellet burner manufacturers, over 50 sorts of wood pellet central heating boilers, 120,000 collections of pellet central heating boilers, 20,000 collections of pellet stoves. As there are still many families using electric heating, the pellet central heating boilers have massive potential.



Sweden pellet burning tools has main heating central heating boiler and biomass range 2 types.



Central heating boiler can be made use of in 1 or even more family members. The thermal send with water. The powers are 10-40kw, which can be readjusted by 30% -100% according to requirements. The central home heating boilers also has 2 types. The consolidated boiler is linked by a pellet burner and also a conventional central heating boiler. The boiler can get in touch with different heaters. The incorporated central heating boilers are mainly imported from Austria as well as Germany, some produced by residential suppliers.



Biomass ranges or furnace

Biomass cooktops also has 2 kinds. Independent pellet cooktop and also Smokeshaft item kind heating system. The former on is extra prominent. The independent pellet oven has a pellet stock bin within, which can hold wood pellets for 2-day usage.



Biomass pellet range can realize automatic dental filling as well as burning. Based upon various feeding technique, pellet cooktops has top feed, lower feed and also horizontal feed 3 kinds. Top feed pellet ovens are the most prominent. Owing to high convenience as well as sanitation, little pellet cooktops sell well in recent years.



Features of Sweden biomass fuel market

Sweden has rich forestry sources as well as bountiful forestry waste, which end up being the major raw materials for biomass pellets.

Sweden wood pellet market has actually been totally marketed. A lot of manufacturers are huge and also moderate firms, with fully grown modern technology. Small wood pellet factories are mostly build on chipboard, furniture as well as saw mills.

The government has actually made detailed legislations as well as plans to drive the wood pellet production. This is why the wood pellet sector develops quickly since the 1990s.

Standard for wood pellet fuel keep boosting. In the 1990s, Sweden published the requirement for wood pellets, as well as measured the method date of pellet fuel and heaters.
