Sweden biomass pellet fuel industry evaluation<br>
Sweden is just one of the world's biggest wood pellet fuel producer and also customer. It's wood pellet production innovation, market policy, and also market model project. In this flow, I will do detailed evaluation on Sweden biomass pellet fuel industry, as well as work out some helpful experiences.



Intro

In the 1970s, numerous nations have actually made policies to promote biomass energy as a way to handle energy dilemma and also atmosphere contamination. Since then, biomass power market has created swiftly, and the innovation keep boosting.



Due to the absence of mineral resources, Sweden's economic climate endured fantastic loss in last century. To guarantee nationwide energy safety and security, Sweden federal government strive to create renewable resource.



Biomass pellet fuel has the attributes of high burning performance, reduced ash material, zero carbon discharge, easy transport, which has actually been preferred in Europe and The United States And Canada. With abundant forestry resources, Sweden pay much focus to the advancement of biomass pellet fuel. Sweden takes up 20% of the world's biomass fuel intake, which grows up at the rate of 8-10%.



Sweden forestry sources and biomass materials

Sweden has plentiful forestry sources. The woodland covers 64% of the acreage, with 51% had by individuals, 24% by huge wood companies, as well as 25% by countries and also various other public organizations. Besides, the forestry grows by 100 million bunches each year, as well as the deforestation quantity is 92.4 million lots. The major forestry sectors are wood handling, paper processing, as well as power wood. The wood materials for making biomass energy mainly originated from the 3 markets above, about 23.48 m3.



Raw materials of wood pellets

Of the raw materials for making wood pellets, wood shavings take up 53%, sawdust 35%, as well as wood chips 5%, others (barks, agriculture deposits, energy forestry) uses up 7%. Some little wood pellet manufacturing facility are developed base upon chipboard, furnishings and sawdust mills.



With more firms taking part in biomass fuel production, the competitors on the raw products come to be more intense. As the crop straws in Sweden are in scattered distribution, they are hard to accumulate as well as refine. So some producers as well as institutes are developing new materials like peat as well as power plants.



Wood pellet manufacturing modern technology and also tools

The pellet molding innovation has actually developed in Sweden. Nowadays, feed machine for poultry has attained business and market production. The manufacturing process features high automation, calling for much less drivers. The picture below presented the wood pellet production procedure.



Drying out: generally, the moisture content of sawdust is around 50%. A drum dryer can decrease the moisture content to 9-12% so that it is gotten approved for making pellets.

Crushing: the dimension of resources must be under 5mm. They need a hammer mill to minimize the dimension.

Conditioning: add high-heat vapor to the raw materials and soften the cellulous in it. More than half of the pellet fuel makers have conditioning process in production.

Pellet molding: a lot of wood pellet factories utilize vertical kind ring die pellet machine. The production capability of one maker 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 maker go to the temperature level of 100 ℃. Pellets under this condition are very easy to damage and inconvenient for transport. A counter-flow cooler can cool the wood pellets in a moderate way.

Packaging: the cooled pellets need to be identified and also packaged according to clients' need. Tiny bags are 16kg, huge bags are 900kg. For big clients like power plant, the wood pellets are carried by trucks as well as ships in bulks.

Biomass pellets category and also application

In 1999, Sweden federal government published the criterion of wood pellet fuel, in which they are classified into 3 courses. The first-rate has high quality. They can be made use of in domestic little burners and stoves.The second as well as third do not have top quality. They are made use of by huge commercial consumers.



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



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



From the 1970s to the 1990s, Sweden regional heating plant embrace coal to change oil. After the enact of CO2 exhaust tax, these heating plant resort 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, regarding 400 local home heating plant has actually adopted wood pellet fuel.



Since the mid 1990s, domestic wood pellet industry has actually made great progression. In the last decades, the use of residential home heating wood pellets grows rapidly. Currently, Sweden has 200,000 households utilizing wood pellet boilers, 40,000 family members making use of wood pellet ovens.



Sweden biomass energy development objective as well as policy

To promote the continual growth of biomass energy, Sweden has actually made a collection of legislations and policies. To ensure the execute of these plans, the federal government additionally made many viable supervision measures and obligatory market requirement.



Sweden not just satisfy the commitment stipulated Kyoto Procedure that reduced greenhouse exhaust by 8%, but additionally established its very own development goal of biomass energy. In 2006, the Priest for lasting growth division claimed that Sweden will entirely utilize biofuels and quit utilizing oil, and also end up being the initial country that completely count on renewable resource.



By 2020, Sweden will certainly enhance its proportion of renewable resource to 50%, the use proportion of renewable energy in transport market to 10%, power efficiency by 20%, as well as cut the emission of greenhouse gas by 40%.



Wood pellet fuel incentive policy

Sweden has accomplished high cost acquisition, financial investment aids, tax obligation decrease and also exemption, quota system and various other biomass power motivation plan.



Since 1975, Sweden spends 36 million Euro from government spending plan to sustain biomass technology advancement. From 1997 to 2002, the government supplied 25% investment subsidy to biomass cogeneration projects. From 2004-2006, the federal government provided 1350 Euros for locals that make use of biomass heating system.



Sweden generally lay high tax obligation on fuels, powers, CO2, SO2, and so on. To advertise the development of biomass energy, to spare all taxes on biomass projects. In 1991, Sweden government begins to lay tax on carbon dioxide emission, that makes the cost of oil as well as fossil fuel increase. Numerous warm supply center and also power plants switches over from fossil fuel to biomass fuel.



To encourage the nuclear power plant to utilize biomass energy, Sweden government introduced electrical power quota system. This plan requires the power distributors to have certain portion of electrical power created by renewable energy. For every 1MWh electrical energy, the government will certainly provide tax obligation relief based upon the biomass power quantity.
