Sweden biomass pellet fuel industry analysis<br>
Sweden is one of the world's largest wood pellet fuel manufacturer and consumer. It's wood pellet manufacturing innovation, industry policy, and market version are prominent. In this flow, I will do detailed analysis on Sweden biomass pellet fuel sector, as well as work out some useful experiences.




Intro

In the 1970s, numerous countries have actually made plans to promote biomass power as a way to cope with power dilemma and also setting air pollution. Ever since, biomass power market has developed rapidly, as well as the innovation maintain boosting.



As a result of the lack of mineral sources, Sweden's economic climate experienced great loss in last century. To make certain national energy security, Sweden federal government make every effort to create renewable resource.



Biomass pellet fuel has the attributes of high burning efficiency, low ash material, no carbon discharge, easy transport, which has actually been popular in Europe and also North America. With bountiful forestry sources, Sweden pay much attention to the advancement 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 resources and biomass products

Sweden has bountiful forestry sources. The forest covers 64% of the acreage, with 51% had by people, 24% by large wood business, as well as 25% by countries and also various other public companies. Besides, the forestry expands by 100 million bunches yearly, and also the deforestation amount is 92.4 million loads. The major forestry industries are wood processing, paper processing, as well as energy wood. The wood materials for making biomass energy mostly come from the 3 markets above, about 23.48 m3.



Resources of wood pellets

Of the raw materials for making wood pellets, wood shavings use up 53%, sawdust 35%, and also wood chips 5%, others (barks, farming residues, energy forestry) occupies 7%. Some tiny wood pellet manufacturing facility are constructed base upon chipboard, furniture and sawdust mills.



With even more firms participating in biomass fuel production, the competitors on the raw products become much more tough. As the plant straws in Sweden remain in scattered distribution, they are difficult to collect and process. So some producers and also institutes are establishing brand-new products like peat as well as energy plants.



Wood pellet manufacturing innovation as well as devices

The pellet molding modern technology has matured in Sweden. Nowadays, it has accomplished commercial and also market production. The manufacturing procedure features high automation, calling for much less operators. The picture listed below showed the wood pellet production process.



Drying: generally, the dampness web content of sawdust is around 50%. A drum clothes dryer can lower the wetness content to 9-12% to ensure that it is gotten making pellets.

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

Conditioning: include high-heat steam to the raw materials and soften the cellulous in it. More than half of the pellet fuel makers have conditioning procedure in manufacturing.

Pellet molding: most wood pellet factories utilize vertical kind ring pass away pellet maker. The production capability of one device is 2-4ton/ h. The life span of ring die is 2000-3000h, while the roller can last 1000-1500h.

Cooling: the wood pellets extruded out from the pellet equipment are at the temperature level of 100 ℃. Pellets under this problem are simple to damage as well as bothersome for transportation. A counter-flow colder can cool off the wood pellets in a modest way.

Packing: the cooled pellets need to be categorized and packaged according to clients' need. Tiny bags are 16kg, big bags are 900kg. For big consumers like power plant, the wood pellets are transferred by trucks and also ships wholesale.

Biomass pellets category as well as application

In 1999, Sweden government released the criterion of wood pellet fuel, in which they are categorized into 3 classes. The extraordinary has premium quality. They can be used in domestic small burners and stoves.The second and also 3rd don't have top quality. They are made use of by big industrial consumers.



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



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



From the 1970s to the 1990s, Sweden regional heating plant embrace coal to change oil. After the establish of carbon dioxide exhaust tax obligation, these home heating plant resort to biomass fuel from coal. In the last decade, the quantity of biomass fuel for heating grows from 1.1 PJ to 57PJ. Currently, about 400 regional heating plant has actually adopted wood pellet fuel.



Because the mid 1990s, domestic wood pellet industry has made wonderful progress. In the last decades, making use of residential heating wood pellets grows rapidly. Currently, Sweden has 200,000 family members making use of wood pellet boilers, 40,000 families utilizing wood pellet cooktops.




Sweden biomass energy development objective and also policy

To advertise the continual advancement of biomass energy, Sweden has made a collection of laws as well as plans. To make certain the execute of these plans, the government likewise made many practical guidance steps and also required market criterion.



Sweden not only accomplish the obligation stated Kyoto Procedure that reduced greenhouse discharge by 8%, yet also established its own advancement goal of biomass power. In 2006, the Minister for lasting development division declared that Sweden will completely use biofuels and stop utilizing oil, and also end up being the very first nation that completely rely upon renewable energy.



By 2020, Sweden will boost its proportion of renewable resource to 50%, the usage proportion of renewable energy in transportation industry to 10%, energy efficiency by 20%, as well as reduced the discharge of greenhouse gas by 40%.



Wood pellet fuel motivation policy

Sweden has executed high rate purchase, investment subsidies, tax obligation reduction and also exemption, quota system and other biomass energy reward plan.



Considering that 1975, Sweden invests 36 million Euro from federal government spending plan to support biomass technology advancement. From 1997 to 2002, the government gave 25% financial investment subsidy to biomass cogeneration tasks. From 2004-2006, the government supplied 1350 Euros for residents who use biomass heater.



Sweden typically lay high tax on fuels, energies, CARBON DIOXIDE, SO2, and so on. To promote the advancement of biomass power, to excuse all taxes on biomass projects. In 1991, Sweden government starts to lay tax obligation on carbon dioxide exhaust, which makes the cost of oil and fossil fuel surge. Numerous warmth supply center as well as power plants switches from nonrenewable fuel source to biomass fuel.



To motivate the nuclear power plant to use biomass power, Sweden government introduced electrical power quota system. This policy requires the power providers to have particular part of electricity created by renewable energy. For every 1MWh electrical power, the federal government will give tax obligation relief based on the biomass power amount.
