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



Introduction

In the 1970s, several nations have made policies to promote biomass power as a way to cope with energy situation as well as setting pollution. Ever since, biomass power industry has actually established rapidly, and the technology keep enhancing.



Because of the absence of mineral resources, Sweden's economic situation endured excellent loss in last century. To guarantee national power protection, Sweden federal government aim to establish renewable energy.



Biomass pellet fuel has the features of high burning efficiency, low ash web content, zero carbon exhaust, very easy transportation, which has actually been preferred in Europe and North America. With abundant forestry sources, Sweden pay much interest to the advancement of biomass pellet fuel. Sweden takes up 20% of the globe's biomass fuel usage, which grows up at the rate of 8-10%.



Sweden forestry sources as well as biomass products

Sweden has plentiful forestry sources. The woodland covers 64% of the acreage, with 51% had by people, 24% by large wood business, and 25% by countries and various other public companies. Besides, the forestry grows by 100 million tons annually, and also the logging quantity is 92.4 million tons. The major forestry sectors are wood processing, paper processing, as well as power wood. The wood products for making biomass energy mostly originated from the 3 sectors above, concerning 23.48 m3.



Raw materials of wood pellets

Of the raw products for making wood pellets, wood shavings use up 53%, sawdust 35%, and wood chips 5%, others (barks, farming deposits, power forestry) occupies 7%. Some little wood pellet manufacturing facility are built base upon chipboard, furnishings and sawdust mills.



With even more firms taking part in biomass fuel production, the competition on the raw products become much more tough. As the plant straws in Sweden remain in scattered circulation, they are hard to accumulate and also refine. So some producers and also institutes are developing brand-new products like peat and energy plants.



Wood pellet producing modern technology and equipment

The pellet molding innovation has grown in Sweden. Nowadays, it has achieved business as well as market production. The production process includes high automation, requiring much less drivers. The picture below displayed the wood pellet production process.




Drying out: usually, the moisture content of sawdust is around 50%. A drum clothes dryer can reduce the dampness web content to 9-12% to make sure that it is qualified for making pellets.

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

Conditioning: add high-heat steam to the raw materials as well as soften the cellulous in it. More than half of the pellet fuel suppliers have conditioning procedure in production.

Pellet molding: most wood pellet manufacturing facilities use upright type ring pass away pellet machine. The production capability of one machine 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 maker are at the temperature level of 100 ℃. Pellets under this problem are simple to damage and also troublesome for transport. A counter-flow colder can cool the wood pellets in a modest method.

Packaging: the cooled down pellets require to be identified and packaged according to consumers' need. Little bags are 16kg, big bags are 900kg. For huge consumers like power plant, the wood pellets are moved by vehicles and ships in bulks.

Biomass pellets classification and application

In 1999, Sweden government released the requirement of wood pellet fuel, in which they are identified right into 3 courses. The excellent has high quality. They can be used in domestic small heaters and stoves.The second as well as third don't have excellent quality. They are made use of by large commercial consumers.



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



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



From the 1970s to the 1990s, Sweden regional heating plant adopt coal to replace oil. After the pass of carbon dioxide emission tax obligation, these home heating plant resort to biomass fuel from coal. In the last decade, the quantity of biomass fuel for home heating expands from 1.1 PJ to 57PJ. Presently, regarding 400 local heating plant has adopted wood pellet fuel.



Considering that the mid 1990s, residential wood pellet sector has actually made wonderful development. In the last decades, the use of domestic home heating wood pellets grows rapidly. Presently, Sweden has 200,000 households making use of wood pellet central heating boilers, 40,000 family members using wood pellet ranges.



Sweden biomass power growth goal as well as policy

To promote the continuous growth of biomass power, Sweden has actually made a series of regulations and also policies. To ensure the execute of these plans, the government additionally made lots of viable supervision actions as well as necessary market standard.



Sweden not just meet the commitment stated Kyoto Procedure that cut greenhouse emission by 8%, however also established its own growth goal of biomass power. In 2006, the Preacher for sustainable growth department declared that Sweden will entirely use biofuels as well as stop using oil, and also end up being the initial nation that totally rely upon renewable resource.



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



Wood pellet fuel reward policy

Sweden has accomplished high rate acquisition, financial investment subsidies, tax obligation decrease as well as exemption, quota system and various other biomass power incentive policy.



Since 1975, Sweden spends 36 million Euro from federal government budget plan to support biomass technology advancement. From 1997 to 2002, the federal government supplied 25% financial investment subsidy to biomass cogeneration jobs. From 2004-2006, the government supplied 1350 Euros for citizens who utilize biomass heating system.



Sweden normally lay high tax obligation on fuels, energies, CO2, SO2, etc. To advertise the development of biomass power, to excuse all taxes on biomass projects. In 1991, Sweden federal government begins to lay tax obligation on carbon dioxide emission, that makes the cost of oil and also fossil fuel surge. feed making machine for sale as well as power plants switches over from nonrenewable fuel source to biomass fuel.



To motivate the nuclear power plant to use biomass energy, Sweden federal government introduced electric power quota system. This plan calls for the power distributors to have specific part of power produced by renewable resource. For every single 1MWh electricity, the federal government will offer tax obligation relief based on the biomass power quantity.



Sweden wood pellet fuel burning tool

Sweden wood pellet melting technology is in the leading placement. There have actually mored than 20 pellet heater producers, over 50 types of wood pellet boilers, 120,000 sets of pellet central heating boilers, 20,000 sets of pellet ovens. As there are still lots of households utilizing electrical home heating, the pellet central heating boilers have big potential.
