Sweden biomass pellet fuel sector analysis<br>
Sweden is one of the world's biggest wood pellet fuel producer as well as consumer. It's wood pellet production modern technology, market plan, and market version project. In this passage, I will do comprehensive evaluation on Sweden biomass pellet fuel industry, and also exercise some valuable experiences.



Introduction

In the 1970s, numerous countries have actually made plans to advertise biomass energy as a means to manage power dilemma and setting contamination. Since then, biomass power industry has actually created swiftly, and also the modern technology maintain enhancing.



As a result of the lack of mineral resources, Sweden's economy experienced terrific loss in last century. To ensure nationwide energy security, Sweden federal government make every effort to establish renewable energy.



Biomass pellet fuel has the features of high burning efficiency, low ash material, no carbon exhaust, very easy transport, which has been popular in Europe as well as North America. With abundant forestry sources, Sweden pay much interest to the development of biomass pellet fuel. Sweden takes up 20% of the world's biomass fuel consumption, which grows up at the speed of 8-10%.



Sweden forestry sources and biomass materials

Sweden has plentiful forestry resources. The woodland covers 64% of the acreage, with 51% owned by individuals, 24% by huge wood business, and 25% by countries and also other public companies. Besides, the forestry grows by 100 million heaps yearly, and the logging amount is 92.4 million lots. The major forestry industries are wood handling, paper handling, as well as power wood. The wood materials for making biomass power mainly come from the 3 industries above, regarding 23.48 m3.



Resources of wood pellets

Of the raw materials for making wood pellets, wood shavings use up 53%, sawdust 35%, and wood chips 5%, others (barks, farming residues, energy forestry) uses up 7%. small wood pellet machine are developed base on chipboard, furniture and also sawdust mills.



With more business participating in biomass fuel production, the competitors on the raw materials become much more intense. As the crop straws in Sweden are in scattered distribution, they are difficult to collect and also process. So some manufacturers as well as institutes are establishing new materials like peat and also power crops.



Wood pellet producing technology and also devices

The pellet molding technology has grown in Sweden. Nowadays, it has actually attained commercial and market manufacturing. The production procedure includes high automation, needing much less operators. The picture listed below displayed the wood pellet manufacturing process.



Drying out: typically, the dampness material of sawdust is around 50%. A drum clothes dryer can reduce the wetness content to 9-12% so that it is gotten approved for making pellets.

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

Conditioning: include high-heat vapor to the raw products and soften the cellulous in it. Over half of the pellet fuel makers have conditioning process in production.

Pellet molding: the majority of wood pellet manufacturing facilities make use of vertical type ring die pellet machine. The manufacturing ability of one device 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 machine go to the temperature of 100 ℃. floating fish feed machine under this condition are simple to damage and inconvenient for transportation. A counter-flow cooler can cool off the wood pellets in a modest means.

Packing: the cooled down pellets need to be identified as well as packaged according to customers' requirement. Little bags are 16kg, big bags are 900kg. For huge customers like nuclear power plant, the wood pellets are transported by trucks as well as ships in bulks.

Biomass pellets classification and also application

In 1999, Sweden federal government released the requirement of wood pellet fuel, in which they are identified right into 3 courses. my sources has premium quality. They can be made use of in residential small heaters as well as stoves.The 2nd and also 3rd do not have high quality. They are utilized by huge industrial customers.



Presently, 57% of the wood pellet fuels in Sweden can satisfy this requirement. Some of them can fulfill the EU standard, others are not generated according to this requirement.



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



From the 1970s to the 1990s, Sweden local home heating plant adopt coal to change oil. After the enact of CO2 discharge tax, these home heating plant look to biomass fuel from coal. In the last decade, the amount of biomass fuel for home heating expands from 1.1 PJ to 57PJ. Currently, concerning 400 local heating plant has actually embraced wood pellet fuel.



Since the mid 1990s, residential wood pellet industry has actually made wonderful progress. In the last decades, the use of residential home heating wood pellets grows rapidly. Presently, Sweden has 200,000 households using wood pellet central heating boilers, 40,000 households making use of wood pellet cooktops.




Sweden biomass power advancement goal and policy

To promote the continuous growth of biomass energy, Sweden has made a series of laws and plans. To make certain the execute of these policies, the government likewise made numerous practical supervision actions and also necessary industry requirement.



Sweden not only satisfy the obligation specified Kyoto Procedure that reduced greenhouse exhaust by 8%, yet likewise set its very own growth goal of biomass power. In 2006, the Priest for lasting growth division declared that Sweden will totally use biofuels and also stop using oil, and also become the initial country that entirely count on renewable resource.



By 2020, Sweden will certainly enhance its percentage of renewable energy to 50%, the usage proportion of renewable energy in transportation market to 10%, power effectiveness by 20%, and also reduced the exhaust of greenhouse gas by 40%.



Wood pellet fuel reward policy

Sweden has accomplished high price procurement, investment subsidies, tax reduction and exception, quota system and various other biomass energy incentive policy.



Given that 1975, Sweden invests 36 million Euro from federal government budget plan to support biomass modern technology development. From 1997 to 2002, the federal government supplied 25% financial investment aid to biomass cogeneration projects. From 2004-2006, the federal government offered 1350 Euros for residents that use biomass heating system.



Sweden generally lay high tax obligation on fuels, energies, CARBON DIOXIDE, SO2, and so on. To promote the growth of biomass energy, to excuse all taxes on biomass projects. In 1991, Sweden government begins to lay tax obligation on carbon dioxide exhaust, which makes the price of oil and also fossil fuel increase. A lot of warmth supply facility as well as power plants changes from fossil fuel to biomass fuel.



To encourage the power plant to make use of biomass energy, Sweden federal government presented electrical power quota system. This policy calls for the power vendors to have particular portion of power created by renewable energy. For each 1MWh electrical power, the federal government will give tax obligation alleviation based upon the biomass power amount.



Sweden wood pellet fuel melting device

Sweden wood pellet burning technology is in the leading setting. There have actually mored than 20 pellet burner manufacturers, over 50 types of wood pellet boilers, 120,000 collections of pellet central heating boilers, 20,000 collections of pellet ranges. As there are still several families using electric home heating, the pellet boilers have substantial capacity.



Sweden pellet burning tools has central heating central heating boiler as well as biomass oven 2 types.



Central heating boiler can be utilized in 1 or even more households. The thermal send with water. The powers are 10-40kw, which can be adjusted by 30% -100% according to requirements. The main heating central heating boilers likewise has 2 kinds. The consolidated boiler is linked by a pellet burner and also a typical boiler. The central heating boiler can get in touch with various burners. The integrated central heating boilers are primarily imported from Austria and Germany, some produced by residential suppliers.



Biomass cooktops or heater

Biomass ranges likewise has 2 types. Independent pellet range as well as Smokeshaft piece type heater. The former on is extra prominent. The independent pellet cooktop has a pellet supply bin within, which can hold wood pellets for 2-day use.




Biomass pellet range can realize automated filling and also burning. Based upon different feeding approach, pellet stoves has leading feed, bottom feed as well as horizontal feed 3 kinds. Top feed pellet cooktops are the most prominent. Owing to high comfort as well as tidiness, little pellet stoves market well recently.



Features of Sweden biomass fuel market

Sweden has abundant forestry resources and abundant forestry waste, which end up being the primary basic materials for biomass pellets.

Sweden wood pellet industry has been totally marketed. Many manufacturers are huge and medium firms, with fully grown innovation. Tiny wood pellet manufacturing facilities are mainly build on chipboard, furnishings as well as saw mills.

The federal government has made detailed laws and also policies to drive the wood pellet production. This is why the wood pellet sector establishes rapidly because the 1990s.

Criterion for wood pellet fuel keep boosting. In the 1990s, Sweden released the requirement for wood pellets, and measured the strategy date of pellet fuel and also burners.

Fully grown burning technology and also equipment. In recent years, Sweden's production of pellet boiler as well as pellet home heating cooktops keep enhancing.

Perfect quality assurance system. Sweden government stipulated that the wood pellet fuel as well as burning devices must get third-party testing qualifications before entering the market.



Conclusion

Sweden is a significant wood pellet fuel producer and also customer in the world. Biomass power plays a vital function in its production and way of life. Around the globe, biomass pellets are mosting likely to play a more important role in heating supply, power generation, as well as industrial manufacturing.
