Sweden biomass pellet fuel industry analysis<br>
Sweden is just one of the world's biggest wood pellet fuel manufacturer and customer. It's wood pellet production modern technology, market policy, and market design project. In this flow, I will certainly do detailed analysis on Sweden biomass pellet fuel sector, as well as exercise some beneficial experiences.



Introduction

In the 1970s, many nations have actually made policies to advertise biomass energy as a way to handle energy dilemma and also setting air pollution. Since then, biomass energy sector has established quickly, and the technology keep boosting.



Because of the absence of mineral sources, Sweden's economic climate experienced fantastic loss in last century. To guarantee national power protection, Sweden federal government make every effort to create renewable resource.



Biomass pellet fuel has the functions of high burning efficiency, low ash content, absolutely no carbon exhaust, very easy transport, which has been preferred in Europe and also The United States And Canada. With bountiful forestry sources, Sweden pay much interest to the growth of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel usage, which grows up at the speed of 8-10%.




Sweden forestry sources and biomass products

Sweden has plentiful forestry sources. The woodland covers 64% of the land area, with 51% owned by people, 24% by big wood business, as well as 25% by countries and also other public companies. Besides, the forestry expands by 100 million loads every year, as well as the logging quantity is 92.4 million bunches. The major forestry markets are wood processing, paper processing, and also energy wood. The wood products for making biomass power generally originated from the 3 sectors above, about 23.48 m3.



Raw materials of wood pellets


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



With even more companies engaging in biomass fuel production, the competition on the raw materials come to be more strong. As the crop straws in Sweden are in scattered distribution, they are tough to gather and process. So some producers and institutes are establishing new products like peat as well as power plants.



Wood pellet making innovation as well as equipment

The pellet molding technology has actually matured in Sweden. Nowadays, it has accomplished business and also market manufacturing. The production process includes high automation, needing much less drivers. The picture below displayed the wood pellet manufacturing procedure.



Drying: normally, the wetness content of sawdust is around 50%. A drum dryer can reduce the wetness content to 9-12% to ensure that it is gotten approved for making pellets.

Crushing: the size of raw materials must be under 5mm. They need a hammer mill to minimize the size.

Conditioning: add high-heat vapor to the raw materials and soften the cellulous in it. Majority of the pellet fuel suppliers have conditioning process in manufacturing.

Pellet molding: many wood pellet factories use upright type ring pass away pellet equipment. The manufacturing 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 machine are at the temperature level of 100 ℃. Pellets under this problem are simple to damage and inconvenient for transportation. A counter-flow colder can cool down the wood pellets in a moderate means.

Packing: the cooled down pellets require to be categorized and also packaged according to clients' need. Small bags are 16kg, large bags are 900kg. For huge consumers like nuclear power plant, the wood pellets are moved by trucks as well as ships in bulks.

Biomass pellets category and application

In 1999, Sweden federal government published the criterion of wood pellet fuel, in which they are categorized into 3 classes. The fabulous has top quality. They can be utilized in domestic small burners and stoves.The second and also third do not have excellent quality. They are used by huge industrial consumers.



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



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



From the 1970s to the 1990s, Sweden local home heating plant adopt coal to change oil. After the enact of CO2 emission tax obligation, these heating plant turn to 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 heating plant has actually adopted wood pellet fuel.



Given that the mid 1990s, residential wood pellet market has made great development. In the last years, the use of domestic heating wood pellets proliferates. Presently, Sweden has 200,000 households making use of wood pellet boilers, 40,000 families utilizing wood pellet ranges.



Sweden biomass energy advancement objective and also policy

To promote the continuous development of biomass energy, Sweden has actually made a series of regulations and plans. To guarantee the carry out of these policies, the federal government also made many viable supervision steps and also mandatory industry criterion.



Sweden not only satisfy the responsibility stipulated Kyoto Procedure that reduced greenhouse discharge by 8%, yet likewise established its own development goal of biomass power. In small pellet feed making machine , the Priest for lasting growth division asserted that Sweden will completely use biofuels and also stop using oil, and come to be the initial country that totally rely on renewable energy.



By 2020, Sweden will certainly enhance its proportion of renewable resource to 50%, the usage ratio of renewable resource in transport sector to 10%, energy efficiency by 20%, and reduced the exhaust of greenhouse gas by 40%.



Wood pellet fuel reward plan

Sweden has actually accomplished high price procurement, investment subsidies, tax reduction and exemption, quota system and also other biomass energy motivation plan.



Since 1975, Sweden spends 36 million Euro from federal government budget plan to support biomass modern technology growth. From 1997 to 2002, the federal government supplied 25% investment subsidy to biomass cogeneration projects. From 2004-2006, the federal government provided 1350 Euros for homeowners that use biomass furnace.



Sweden usually lay high tax obligation on fuels, powers, CO2, SO2, etc. To advertise the advancement of biomass energy, to excuse all taxes on biomass projects. In 1991, Sweden government begins to lay tax on carbon dioxide discharge, that makes the rate of oil as well as fossil fuel rise. Numerous warm supply center as well as nuclear power plant switches from nonrenewable fuel source to biomass fuel.



To motivate the power plant to use biomass power, Sweden federal government introduced electrical power quota system. This policy requires the power vendors to have particular section of power created by renewable energy. For every 1MWh electrical energy, the government will provide tax alleviation based upon the biomass power quantity.
