Sweden biomass pellet fuel sector evaluation<br>
Sweden is among the world's largest wood pellet fuel producer and also consumer. It's wood pellet production modern technology, market policy, as well as market version are prominent. In rice husk pellet machine , I will certainly do thorough evaluation on Sweden biomass pellet fuel market, and work out some valuable experiences.



Introduction

In the 1970s, several nations have made policies to advertise biomass power as a method to handle power crisis as well as environment air pollution. Ever since, biomass power industry has established rapidly, and the technology maintain improving.




Due to the lack of mineral sources, Sweden's economy experienced fantastic loss in last century. To guarantee nationwide power protection, Sweden federal government aim to develop renewable resource.



Biomass pellet fuel has the functions of high burning efficiency, low ash material, absolutely no carbon exhaust, simple transportation, which has actually been preferred in Europe and North America. With abundant forestry sources, Sweden pay much interest to the growth of biomass pellet fuel. Sweden takes up 20% of the world's biomass fuel usage, 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 land area, with 51% possessed by individuals, 24% by huge wood business, and also 25% by nations and also other public organizations. Besides, the forestry grows by 100 million heaps every year, as well as the logging quantity is 92.4 million bunches. The major forestry sectors are wood processing, paper processing, and power wood. The wood materials for making biomass energy mainly originated from the 3 industries 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%, and also wood chips 5%, others (barks, farming deposits, energy forestry) occupies 7%. Some tiny wood pellet factory are constructed base upon chipboard, furniture and sawdust mills.



With even more companies engaging in biomass fuel manufacturing, the competition on the raw products end up being a lot more intense. As the plant straws in Sweden remain in scattered circulation, they are hard to collect and refine. So some producers and institutes are establishing new products like peat and power plants.



Wood pellet manufacturing modern technology as well as equipment

The pellet molding modern technology has actually developed in Sweden. Nowadays, it has achieved commercial and market production. The production process includes high automation, requiring less operators. The picture listed below displayed the wood pellet production procedure.



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

Crushing: the dimension of raw materials need to be under 5mm. They require a hammer mill to reduce the dimension.

Conditioning: add high-heat heavy steam to the raw materials as well as soften the cellulous in it. Majority of the pellet fuel manufacturers have conditioning process in manufacturing.

Pellet molding: the majority of wood pellet manufacturing facilities use vertical kind ring die pellet maker. The manufacturing ability of one maker is 2-4ton/ h. olx pellet machine of ring die is 2000-3000h, while the roller can last 1000-1500h.

Air conditioning: the wood pellets extruded out from the pellet equipment go to the temperature of 100 ℃. Pellets under this problem are easy to break and also inconvenient for transportation. A counter-flow cooler can cool off the wood pellets in a moderate means.

Packing: the cooled pellets require to be categorized as well as packaged according to consumers' requirement. Small bags are 16kg, large bags are 900kg. For large customers like power plant, the wood pellets are carried by trucks as well as ships wholesale.

Biomass pellets category and also application

In 1999, Sweden federal government released the requirement of wood pellet fuel, in which they are categorized into 3 courses. The fabulous has excellent quality. They can be made use of in residential tiny burners as well as stoves.The 2nd and also third do not have top quality. They are used by big industrial consumers.



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



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



From the 1970s to the 1990s, Sweden local home heating plant embrace coal to change oil. After the pass of CO2 discharge tax, these home heating plant turn to biomass fuel from coal. In the last decade, the quantity of biomass fuel for home heating grows from 1.1 PJ to 57PJ. Currently, regarding 400 local heating plant has actually embraced wood pellet fuel.



Given that the mid 1990s, domestic wood pellet sector has actually made wonderful progression. In the last years, using domestic home heating wood pellets proliferates. Currently, Sweden has 200,000 family members using wood pellet central heating boilers, 40,000 families using wood pellet ovens.



Sweden biomass energy development goal and also plan

To advertise the continual growth of biomass energy, Sweden has actually made a series of laws as well as plans. To ensure the implement of these policies, the government also made several practical guidance actions and also necessary market requirement.



Sweden not only accomplish the obligation stated Kyoto Method that reduced greenhouse exhaust by 8%, but also established its own development objective of biomass power. In 2006, the Priest for sustainable growth division asserted that Sweden will entirely make use of biofuels as well as stop making use of oil, and become the very first nation that totally count on renewable resource.



By 2020, Sweden will raise its percentage of renewable energy to 50%, the use ratio of renewable resource in transportation sector to 10%, power performance by 20%, and also reduced the discharge of greenhouse gas by 40%.



Wood pellet fuel reward plan

Sweden has actually executed high cost acquisition, investment subsidies, tax decrease and also exemption, quota system as well as other biomass energy incentive plan.



Since 1975, Sweden invests 36 million Euro from government budget plan to support biomass modern technology development. From 1997 to 2002, the government supplied 25% investment aid to biomass cogeneration projects. From 2004-2006, the federal government gave 1350 Euros for residents that use biomass heating unit.



Sweden normally lay high tax obligation on fuels, powers, CARBON DIOXIDE, SO2, etc. To advertise the advancement of biomass power, to spare all taxes on biomass jobs. In 1991, Sweden federal government starts to lay tax on carbon dioxide discharge, that makes the rate of oil and also nonrenewable fuel source increase. So many 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 energy, Sweden government introduced electrical power quota system. This plan requires the power distributors to have certain portion of electrical power generated by renewable energy. For every 1MWh electrical power, the federal government will give tax relief based on the biomass power quantity.
