Sweden biomass pellet fuel sector evaluation<br>
Sweden is among the globe's largest wood pellet fuel manufacturer as well as customer. It's wood pellet manufacturing modern technology, industry policy, and also market design are prominent. In this passage, I will do detailed analysis on Sweden biomass pellet fuel market, and also exercise some useful experiences.



Introduction

In the 1970s, many nations have made plans to advertise biomass power as a way to handle power dilemma and environment pollution. Since then, biomass energy industry has developed quickly, and the modern technology keep boosting.



Because of the lack of mineral sources, Sweden's economy experienced fantastic loss in last century. To guarantee national energy safety, Sweden federal government make every effort to develop renewable resource.



Biomass pellet fuel has the attributes of high burning performance, reduced ash content, zero carbon exhaust, easy transport, which has actually been preferred in Europe and also The United States And Canada. With plentiful forestry sources, Sweden pay much interest to the development of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel usage, which grows up at the rate of 8-10%.



Sweden forestry resources as well as biomass products

Sweden has abundant forestry sources. fish pellet machine price covers 64% of the acreage, with 51% owned by people, 24% by big wood firms, as well as 25% by countries and other public organizations. Besides, the forestry expands by 100 million loads every year, and also the logging amount is 92.4 million loads. The major forestry sectors are wood processing, paper processing, and energy wood. The wood materials for making biomass power mainly originated from the 3 markets above, regarding 23.48 m3.



Resources of wood pellets

Of the raw products for making wood pellets, wood shavings take up 53%, sawdust 35%, and wood chips 5%, others (barks, agriculture deposits, power forestry) occupies 7%. Some tiny wood pellet manufacturing facility are developed base on chipboard, furnishings and sawdust mills.



With more business engaging in biomass fuel production, the competitors on the raw products end up being more fierce. As the crop straws in Sweden are in scattered circulation, they are hard to gather as well as process. So some manufacturers as well as institutes are establishing new materials like peat and also energy plants.



Wood pellet manufacturing technology as well as tools

The pellet molding innovation has grown in Sweden. Nowadays, it has actually attained commercial and also market manufacturing. The production process features high automation, requiring less operators. 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 decrease the dampness material to 9-12% to ensure that it is gotten approved for making pellets.

Crushing: the dimension of resources ought to be under 5mm. They require a hammer mill to decrease the size.

Conditioning: add high-heat heavy steam to the raw materials as well as soften the cellulous in it. Over half of the pellet fuel suppliers have conditioning process in production.

Pellet molding: most wood pellet factories make use of upright type ring die pellet maker. The manufacturing capacity 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 equipment go to the temperature level of 100 ℃. Pellets under this condition are very easy to damage as well as inconvenient for transportation. A counter-flow cooler can cool down the wood pellets in a moderate way.

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

Biomass pellets category and application

In 1999, Sweden federal government published the criterion of wood pellet fuel, in which they are classified right into 3 classes. The excellent has excellent quality. They can be used in domestic tiny heaters and also stoves.The 2nd as well as 3rd don't have high quality. fish feed machine price are made use of by large industrial customers.



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



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



From the 1970s to the 1990s, Sweden local heating plant embrace coal to replace oil. After the pass of carbon dioxide discharge tax obligation, these heating plant rely on biomass fuel from coal. In the last years, the amount of biomass fuel for home heating grows from 1.1 PJ to 57PJ. Presently, about 400 regional home heating plant has actually embraced wood pellet fuel.



Considering that the mid 1990s, residential wood pellet industry has actually made fantastic development. In the last years, making use of residential heating wood pellets proliferates. Currently, Sweden has 200,000 family members using wood pellet central heating boilers, 40,000 family members using wood pellet cooktops.



Sweden biomass power development goal as well as policy

To promote the continual advancement of biomass power, Sweden has made a collection of regulations as well as policies. To guarantee the implement of these plans, the federal government likewise made several viable supervision steps and mandatory sector criterion.



Sweden not only satisfy the responsibility stipulated Kyoto Protocol that cut greenhouse exhaust by 8%, however additionally set its own development goal of biomass power. In 2006, the Preacher for lasting growth department declared that Sweden will entirely use biofuels and stop making use of oil, and also become the first country that totally count on renewable resource.



By 2020, Sweden will certainly enhance its percentage of renewable energy to 50%, the usage ratio of renewable resource in transport industry to 10%, power performance by 20%, as well as reduced the emission of greenhouse gas by 40%.



Wood pellet fuel motivation policy

Sweden has actually performed high cost purchase, investment aids, tax obligation decrease and also exemption, quota system and other biomass power reward policy.



Considering that 1975, Sweden invests 36 million Euro from federal government budget plan to sustain biomass innovation advancement. From 1997 to 2002, the federal government gave 25% financial investment subsidy to biomass cogeneration tasks. From 2004-2006, the government gave 1350 Euros for locals who utilize biomass furnace.



Sweden usually lay high tax obligation on fuels, energies, CO2, SO2, and so on. To promote the advancement of biomass energy, to spare all taxes on biomass jobs. In 1991, Sweden federal government begins to lay tax obligation on CO2 exhaust, which makes the rate of oil and also nonrenewable fuel source surge. Many warmth supply center and also power plants switches over from nonrenewable fuel source to biomass fuel.



To urge the power plant to utilize biomass power, Sweden government presented electric power quota system. This policy calls for the power suppliers to have certain portion of electricity generated by renewable resource. For every single 1MWh electricity, the government will certainly give tax obligation alleviation based on the biomass power quantity.



Sweden wood pellet fuel shedding tool

Sweden wood pellet burning technology is in the leading position. There have actually been over 20 pellet heater producers, over 50 sorts of wood pellet central heating boilers, 120,000 collections of pellet central heating boilers, 20,000 collections of pellet cooktops. As there are still numerous family members making use of electric heating, the pellet boilers have massive potential.



Sweden pellet burning devices has central heating boiler and also biomass range 2 kinds.



Central heating central heating boiler can be made use of in 1 or even more families. The thermal transmit with water. The powers are 10-40kw, which can be adjusted by 30% -100% according to requirements. The central home heating boilers also has 2 kinds. The combined central heating boiler is linked by a pellet heater and also a typical boiler. The central heating boiler can connect with various burners. The integrated boilers are primarily imported from Austria as well as Germany, some generated by domestic producers.



Biomass ranges or heater

Biomass ranges also has 2 kinds. Independent pellet stove and also Smokeshaft item kind heating system. The former on is a lot more prominent. The independent pellet stove has a pellet supply container within, which can hold wood pellets for 2-day use.



Biomass pellet range can realize automatic filling and also burning. Based on various feeding technique, pellet ranges has leading feed, bottom feed and straight feed 3 types. Top feed pellet stoves are one of the most popular. Owing to high benefit and also cleanliness, small pellet stoves market well recently.



Attributes of Sweden biomass fuel sector
