Sweden biomass pellet fuel market evaluation<br>
Sweden is just one of the globe's largest wood pellet fuel producer as well as customer. It's wood pellet manufacturing innovation, sector plan, and market model are prominent. In this flow, I will certainly do comprehensive analysis on Sweden biomass pellet fuel industry, and work out some useful experiences.



Intro

In the 1970s, many nations have made policies to promote biomass energy as a way to deal with energy situation as well as environment air pollution. Ever since, biomass power sector has developed quickly, and also the modern technology keep enhancing.



Because of the lack of mineral sources, Sweden's economic situation endured terrific loss in last century. To make certain nationwide power security, Sweden federal government make every effort to establish renewable energy.



Biomass pellet fuel has the functions of high burning efficiency, reduced ash content, zero carbon exhaust, very easy transport, which has actually been preferred in Europe and also North America. With plentiful forestry sources, Sweden pay much interest to the development of biomass pellet fuel. Sweden uses up 20% of the globe's biomass fuel intake, which grows up at the rate of 8-10%.



Sweden forestry sources as well as biomass materials

Sweden has abundant forestry resources. The woodland covers 64% of the land area, with 51% owned by people, 24% by big wood companies, and also 25% by nations and also other public organizations. Besides, the forestry grows by 100 million heaps every year, as well as the deforestation amount is 92.4 million bunches. The significant forestry industries are wood handling, paper processing, and energy wood. The wood materials for making biomass energy generally come from the 3 industries above, concerning 23.48 m3.



Basic material of wood pellets

Of the raw products for making wood pellets, wood shavings occupy 53%, sawdust 35%, and also wood chips 5%, others (barks, agriculture residues, power forestry) uses up 7%. Some tiny wood pellet factory are constructed base upon chipboard, furniture as well as sawdust mills.



With even more firms engaging in biomass fuel production, the competition on the raw materials come to be a lot more strong. As the plant straws in Sweden are in scattered distribution, they are hard to gather and also refine. So some producers and also institutes are creating brand-new materials like peat as well as power crops.




Wood pellet producing modern technology and equipment

The pellet molding innovation has matured in Sweden. Nowadays, it has achieved industrial as well as market production. The manufacturing procedure features high automation, calling for much less operators. The picture below presented the wood pellet production procedure.



Drying: normally, the moisture material of sawdust is around 50%. A drum dryer can lower the moisture content to 9-12% so that it is qualified for making pellets.

Crushing: the size of resources should be under 5mm. They need a hammer mill to reduce the dimension.

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

Pellet molding: a lot of wood pellet manufacturing facilities use vertical kind ring pass away pellet equipment. The manufacturing ability 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 device are at the temperature of 100 ℃. Pellets under this condition are very easy to damage and also bothersome for transport. A counter-flow colder can cool down the wood pellets in a modest way.

Packaging: the cooled pellets need to be categorized as well as packaged according to consumers' demand. Tiny bags are 16kg, big bags are 900kg. For large clients like nuclear power plant, the wood pellets are carried by vehicles as well as ships in bulks.

Biomass pellets category and application

In 1999, Sweden federal government released the standard of wood pellet fuel, in which they are classified into 3 classes. The first class has high quality. They can be used in residential small heaters and also stoves.The 2nd and third don't have excellent quality. They are used by huge commercial consumers.



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



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



From the 1970s to the 1990s, Sweden local heating plant take on coal to change oil. After the pass of CO2 exhaust tax, these home heating plant resort to biomass fuel from coal. In the last years, the quantity of biomass fuel for home heating grows from 1.1 PJ to 57PJ. Currently, concerning 400 regional home heating plant has taken on wood pellet fuel.



Since the mid 1990s, domestic wood pellet sector has actually made wonderful progression. In the last decades, making use of domestic heating wood pellets proliferates. Currently, Sweden has 200,000 family members making use of wood pellet central heating boilers, 40,000 households making use of wood pellet cooktops.



Sweden biomass power development goal and plan

To advertise the continuous growth of biomass energy, Sweden has actually made a series of regulations and also plans. To ensure the apply of these plans, the federal government likewise made many viable guidance steps and necessary sector criterion.



Sweden not just fulfill the responsibility stipulated Kyoto Protocol that reduced greenhouse discharge by 8%, yet also established its very own advancement objective of biomass power. In 2006, the Minister for lasting advancement division asserted that Sweden will totally utilize biofuels and quit utilizing oil, as well as end up being the first country that entirely depend on renewable resource.



By 2020, Sweden will certainly increase its percentage of renewable resource to 50%, the use ratio of renewable energy in transport market to 10%, energy efficiency by 20%, and also reduced the exhaust of greenhouse gas by 40%.



Wood pellet fuel reward policy

Sweden has accomplished high price purchase, investment subsidies, tax decrease and exemption, quota system and also various other biomass energy reward plan.



Since 1975, Sweden invests 36 million Euro from federal government spending plan to support biomass modern technology advancement. From 1997 to 2002, the federal government provided 25% investment subsidy to biomass cogeneration projects. From richi pellet machine -2006, the federal government supplied 1350 Euros for homeowners who make use of biomass heating system.



Sweden typically lay high tax obligation on fuels, powers, CO2, SO2, and so on. To advertise the development of biomass power, to spare all tax obligations on biomass projects. In 1991, Sweden federal government begins to lay tax on carbon dioxide emission, that makes the rate of oil and nonrenewable fuel source increase. A lot of warmth supply center and also nuclear power plant changes from fossil fuel to biomass fuel.



To encourage the power plant to use biomass power, Sweden government presented electric power quota system. This plan requires the power distributors to have particular section of power created by renewable energy. For every 1MWh electrical energy, the federal government will give tax alleviation based upon the biomass power quantity.
