Sweden biomass pellet fuel market evaluation<br>
Sweden is one of the world's largest wood pellet fuel producer and also customer. It's wood pellet manufacturing modern technology, market plan, and market version project. In this flow, I will certainly do extensive analysis on Sweden biomass pellet fuel sector, as well as work out some beneficial experiences.



Intro

In the 1970s, several nations have made plans to advertise biomass power as a method to deal with power dilemma and also atmosphere air pollution. Ever since, biomass energy sector has actually established rapidly, and the modern technology keep boosting.



Because of the lack of mineral resources, Sweden's economic situation suffered terrific loss in last century. To make certain national power safety and security, Sweden federal government strive to develop renewable energy.



Biomass pellet fuel has the attributes of high burning efficiency, reduced ash content, absolutely no carbon exhaust, easy transportation, which has actually been popular in Europe and North America. With plentiful forestry resources, Sweden pay much interest to the growth of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel consumption, which matures at the speed of 8-10%.



Sweden forestry sources and biomass products

Sweden has abundant forestry resources. The woodland covers 64% of the land area, with 51% owned by individuals, 24% by huge wood business, and 25% by countries as well as other public organizations. Besides, the forestry expands by 100 million heaps annually, and the logging amount is 92.4 million bunches. The major forestry sectors are wood handling, paper processing, as well as power wood. The wood products for making biomass power primarily originated from the 3 markets above, regarding 23.48 m3.



Raw materials of wood pellets

Of the raw materials for making wood pellets, wood shavings occupy 53%, sawdust 35%, and also wood chips 5%, others (barks, farming deposits, power forestry) uses up 7%. Some little wood pellet manufacturing facility are constructed base on chipboard, furniture and also sawdust mills.



With more firms participating in biomass fuel production, the competition on the raw products end up being much more intense. As the plant straws in Sweden are in scattered distribution, they are hard to collect and also process. So some manufacturers as well as institutes are developing brand-new materials like peat and energy crops.



Wood pellet manufacturing technology and equipment

The pellet molding innovation has grown in Sweden. Nowadays, it has accomplished business as well as market production. The manufacturing procedure features high automation, needing much less drivers. The picture listed below presented the wood pellet manufacturing process.



Drying: typically, the wetness content of sawdust is around 50%. A drum clothes dryer can lower the dampness material to 9-12% to make sure that it is qualified for making pellets.

Crushing: the size of basic materials ought to 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 producers have conditioning procedure in manufacturing.

Pellet molding: a lot of wood pellet factories use upright kind ring die pellet equipment. The manufacturing ability of one machine is 2-4ton/ h. The service life 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 condition are easy to break and also troublesome for transport. A counter-flow colder can cool the wood pellets in a moderate way.

Packaging: the cooled down pellets require to be categorized and packaged according to clients' need. Little bags are 16kg, large bags are 900kg. For big clients like nuclear power plant, the wood pellets are transported by vehicles and also ships in bulks.

Biomass pellets classification and application

In 1999, Sweden federal government released the standard of wood pellet fuel, in which they are classified into 3 classes. The excellent has top quality. They can be utilized in domestic small heaters as well as stoves.The second and third do not have premium quality. They are used by big industrial customers.



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



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



From the 1970s to the 1990s, Sweden local home heating plant adopt coal to change oil. After the establish of carbon dioxide exhaust tax, these home heating plant count on biomass fuel from coal. In the last years, the amount of biomass fuel for home heating expands from 1.1 PJ to 57PJ. Presently, about 400 regional heating plant has actually embraced wood pellet fuel.



Given that the mid 1990s, domestic wood pellet market has actually made fantastic progression. In the last years, the use of domestic heating wood pellets grows rapidly. Presently, Sweden has 200,000 families utilizing wood pellet central heating boilers, 40,000 families using wood pellet cooktops.



Sweden biomass energy advancement goal and plan

To promote the continuous growth of biomass power, Sweden has made a collection of regulations and policies. To guarantee the apply of these policies, the federal government likewise made lots of possible guidance steps and required sector requirement.



Sweden not only satisfy the obligation specified Kyoto Protocol that cut greenhouse discharge by 8%, but likewise set its own growth objective of biomass power. In 2006, the Priest for lasting growth department claimed that Sweden will totally make use of biofuels and also stop using oil, and also become the very first nation that totally rely on renewable resource.



By 2020, Sweden will increase its percentage of renewable energy to 50%, the use proportion of renewable energy in transport industry to 10%, power performance by 20%, as well as cut the exhaust of greenhouse gas by 40%.




Wood pellet fuel motivation plan

Sweden has carried out high price procurement, financial investment aids, tax reduction and also exception, quota system as well as other biomass energy incentive policy.



Given that 1975, Sweden invests 36 million Euro from federal government spending plan to sustain biomass modern technology growth. From 1997 to 2002, the federal government gave 25% investment subsidy to biomass cogeneration jobs. From 2004-2006, the federal government offered 1350 Euros for locals who use biomass heater.



Sweden usually lay high tax obligation on fuels, powers, CO2, SO2, etc. To advertise the advancement of biomass energy, to spare all tax obligations on biomass jobs. In 1991, Sweden federal government begins to lay tax obligation on CO2 exhaust, which makes the price of oil and also fossil fuel rise. So many heat supply center and also nuclear power plant switches over from nonrenewable fuel source to biomass fuel.



To urge the nuclear power plant to make use of biomass power, Sweden government introduced electrical power quota system. This policy needs the power providers to have specific part of electrical power produced by renewable resource. For every single 1MWh electrical energy, the government will certainly offer tax alleviation based upon the biomass power amount.



Sweden wood pellet fuel melting gadget

Sweden wood pellet melting innovation remains in the leading position. There have actually been over used feed pellet mill for sale , over 50 types of wood pellet central heating boilers, 120,000 collections of pellet boilers, 20,000 sets of pellet stoves.
