Sweden biomass pellet fuel sector analysis<br>
Sweden is among the world's largest wood pellet fuel manufacturer and also consumer. It's wood pellet manufacturing modern technology, market plan, and also market design project. In this passage, I will do extensive evaluation on Sweden biomass pellet fuel industry, as well as exercise some useful experiences.



Intro

In the 1970s, many nations have made plans to promote biomass energy as a means to handle energy dilemma and atmosphere pollution. Since then, biomass energy market has created quickly, as well as the modern technology maintain enhancing.



As a result of the lack of mineral resources, Sweden's economy suffered excellent loss in last century. To guarantee nordson pelletizer , Sweden government make every effort to develop renewable energy.



Biomass pellet fuel has the functions of high burning effectiveness, reduced ash web content, absolutely no carbon discharge, very easy transportation, which has been prominent in Europe and The United States And Canada. With abundant forestry resources, Sweden pay much attention to the advancement of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel usage, which matures at the rate of 8-10%.



Sweden forestry resources and also biomass materials

Sweden has bountiful forestry resources. The woodland covers 64% of the acreage, with 51% had by individuals, 24% by huge wood business, as well as 25% by countries and various other public companies. Besides, the forestry grows by 100 million heaps annually, and the deforestation amount is 92.4 million lots. The major forestry industries are wood processing, paper processing, as well as power wood. The wood products for making biomass power generally 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 use up 53%, sawdust 35%, and also wood chips 5%, others (barks, agriculture residues, power forestry) occupies 7%. Some tiny wood pellet factory are constructed base on chipboard, furnishings as well as sawdust mills.



With more companies taking part in biomass fuel manufacturing, the competitors on the raw products become more fierce. As the crop straws in Sweden remain in scattered distribution, they are hard to gather as well as refine. So some manufacturers as well as institutes are creating new materials like peat and energy plants.



Wood pellet manufacturing modern technology and also tools

The pellet molding innovation has developed in Sweden. Nowadays, it has actually attained industrial and market production. The manufacturing process includes high automation, requiring much less drivers. The picture listed below displayed the wood pellet production process.



Drying out: generally, the dampness material of sawdust is around 50%. A drum clothes dryer can reduce the moisture content to 9-12% to make sure that it is qualified for making pellets.

Crushing: the size of basic materials ought to be under 5mm. They need a hammer mill to decrease the dimension.

Conditioning: add high-heat steam to the raw products and soften the cellulous in it. Over half of the pellet fuel makers have conditioning procedure in manufacturing.

Pellet molding: a lot of wood pellet manufacturing facilities make use of upright kind ring die pellet device. The production ability of one equipment 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 device go to the temperature level of 100 ℃. Pellets under this condition are easy to damage as well as troublesome for transport. A counter-flow colder can cool the wood pellets in a moderate method.

Packing: the cooled down pellets require to be classified and also packaged according to consumers' need. Little bags are 16kg, huge bags are 900kg. For huge consumers like power plant, the wood pellets are carried by vehicles and also ships wholesale.

Biomass pellets category as well as application

In 1999, Sweden government published the requirement of wood pellet fuel, in which they are categorized right into 3 classes. The excellent has high quality. They can be used in residential small heaters and also stoves.The second as well as 3rd do not have top quality. They are used by large commercial clients.



Currently, 57% of the wood pellet fuels in Sweden can fulfill this criterion. Several of them can satisfy the EU criterion, others are not created according to this requirement.



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




From the 1970s to the 1990s, Sweden regional heating plant adopt coal to change oil. After the establish of carbon dioxide discharge tax obligation, these home heating plant resort to biomass fuel from coal. In the last years, the quantity of biomass fuel for heating grows from 1.1 PJ to 57PJ. Currently, concerning 400 local heating plant has actually embraced wood pellet fuel.



Since the mid 1990s, domestic wood pellet sector has made terrific development. In the last decades, the use of domestic heating wood pellets proliferates. Currently, Sweden has 200,000 households making use of wood pellet central heating boilers, 40,000 families making use of wood pellet ovens.



Sweden biomass power development goal and plan

To promote the constant development of biomass energy, Sweden has actually made a series of regulations as well as plans. To guarantee the implement of these plans, the federal government likewise made lots of viable supervision procedures and necessary sector standard.



Sweden not only accomplish the commitment specified Kyoto Protocol that reduced greenhouse emission by 8%, but additionally set its own advancement goal of biomass power. In 2006, the Preacher for lasting advancement department asserted that Sweden will entirely use biofuels as well as quit utilizing oil, as well as end up being the very first nation that totally depend on renewable energy.



By 2020, Sweden will certainly increase its proportion of renewable resource to 50%, the usage ratio of renewable resource in transport industry to 10%, energy effectiveness by 20%, and also cut the discharge of greenhouse gas by 40%.



Wood pellet fuel reward plan

Sweden has actually accomplished high cost acquisition, financial investment subsidies, tax decrease and also exemption, quota system as well as other biomass energy incentive policy.



Considering that 1975, Sweden invests 36 million Euro from government spending plan to support biomass technology advancement. From 1997 to 2002, the federal government provided 25% financial investment aid to biomass cogeneration tasks. From 2004-2006, the government gave 1350 Euros for locals that make use of biomass heating unit.



Sweden normally lay high tax on fuels, energies, CARBON DIOXIDE, SO2, and so on. To advertise the advancement of biomass energy, to excuse all tax obligations on biomass tasks. In 1991, Sweden federal government starts to lay tax obligation on carbon dioxide exhaust, that makes the price of oil and also nonrenewable fuel source increase. A lot of warm supply facility and nuclear power plant switches over from nonrenewable fuel source to biomass fuel.



To urge the nuclear power plant to utilize biomass energy, Sweden government presented electric power quota system. This policy needs the power providers to have particular part of electrical energy produced by renewable resource. For each 1MWh electricity, the federal government will certainly offer tax relief based on the biomass power amount.



Sweden wood pellet fuel melting device

Sweden wood pellet burning innovation is in the leading position. There have actually been over 20 pellet burner producers, over 50 sorts of wood pellet boilers, 120,000 sets of pellet central heating boilers, 20,000 collections of pellet ranges.
