Sweden biomass pellet fuel sector evaluation<br>
Sweden is one of the globe's biggest wood pellet fuel producer and also consumer. It's wood pellet manufacturing modern technology, industry policy, and market design project. In this flow, I will do extensive evaluation on Sweden biomass pellet fuel industry, and also work out some beneficial experiences.



Intro

In the 1970s, several nations have actually made plans to promote biomass power as a method to deal with energy situation and also environment pollution. Ever since, biomass power sector has actually established swiftly, and also the technology keep improving.



Due to the absence of mineral resources, Sweden's economy endured fantastic loss in last century. To make sure nationwide power protection, Sweden government aim to develop renewable energy.



Biomass pellet fuel has the attributes of high burning effectiveness, reduced ash material, absolutely no carbon exhaust, very easy transportation, which has been prominent in Europe and North America. With bountiful forestry sources, Sweden pay much attention to the development of biomass pellet fuel. Sweden occupies 20% of the world's biomass fuel usage, which grows up at the rate of 8-10%.



Sweden forestry resources as well as biomass products

Sweden has bountiful forestry sources. The forest covers 64% of the acreage, with 51% owned by people, 24% by huge wood firms, and also 25% by nations as well as other public companies. Besides, the forestry grows by 100 million loads annually, as well as the logging amount is 92.4 million bunches. dog pellet machine are wood handling, paper processing, and energy wood. The wood materials for making biomass energy primarily come from the 3 industries above, about 23.48 m3.



Resources of wood pellets

Of the raw products for making wood pellets, wood shavings take up 53%, sawdust 35%, and wood chips 5%, others (barks, agriculture residues, power forestry) uses up 7%. food pellet making machine manufacturing facility are constructed base on chipboard, furnishings as well as sawdust mills.




With more companies participating in biomass fuel manufacturing, the competition on the raw products end up being more intense. As the plant straws in Sweden remain in scattered circulation, they are tough to accumulate as well as refine. So some manufacturers and institutes are creating brand-new materials like peat and also power crops.



Wood pellet producing technology and also tools

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



Drying: normally, the moisture web content of sawdust is around 50%. A drum dryer can lower the dampness material to 9-12% so that it is gotten making pellets.

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

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

Pellet molding: the majority of wood pellet manufacturing facilities utilize vertical kind ring die pellet machine. The manufacturing capability of one equipment is 2-4ton/ h. The life span of ring die is 2000-3000h, while the roller can last 1000-1500h.

Air conditioning: the wood pellets extruded out from the pellet device are at the temperature level of 100 ℃. machine a pellet under this problem are easy to break as well as inconvenient for transport. A counter-flow colder can cool down the wood pellets in a modest means.

Packaging: the cooled pellets need to be classified and packaged according to customers' need. Small bags are 16kg, large bags are 900kg. For big consumers like nuclear power plant, the wood pellets are transferred by vehicles as well as ships in bulks.

Biomass pellets category and also application

In 1999, Sweden government published the requirement of wood pellet fuel, in which they are categorized into 3 classes. The first-rate has top quality. They can be used in domestic little burners as well as stoves.The second and 3rd do not have top quality. They are made use of by huge commercial clients.



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



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




From the 1970s to the 1990s, Sweden local home heating plant take on coal to replace oil. After the establish of carbon dioxide emission tax obligation, these heating plant look to biomass fuel from coal. In the last decade, the quantity of biomass fuel for home heating grows from 1.1 PJ to 57PJ. Presently, concerning 400 regional heating plant has adopted wood pellet fuel.



Because the mid 1990s, domestic wood pellet industry has made fantastic development. In the last years, making use of domestic home heating wood pellets proliferates. Presently, Sweden has 200,000 family members utilizing wood pellet boilers, 40,000 family members utilizing wood pellet ranges.



Sweden biomass energy development goal and also plan

To advertise the continual development of biomass energy, Sweden has actually made a collection of regulations as well as policies. To guarantee the implement of these plans, the federal government additionally made lots of possible guidance actions and required industry requirement.



Sweden not only fulfill the responsibility stipulated Kyoto Protocol that reduced greenhouse emission by 8%, yet additionally set its very own development goal of biomass energy. In 2006, the Minister for sustainable growth division asserted that Sweden will entirely make use of biofuels and quit making use of oil, and become the initial nation that totally rely upon renewable energy.



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



Wood pellet fuel incentive plan

Sweden has actually carried out high rate acquisition, investment subsidies, tax reduction and also exemption, quota system as well as other biomass power motivation plan.



Since 1975, Sweden invests 36 million Euro from government spending plan to support biomass technology development. From 1997 to 2002, the government supplied 25% financial investment subsidy to biomass cogeneration projects. From 2004-2006, the federal government provided 1350 Euros for homeowners that utilize biomass heating system.



Sweden normally lay high tax obligation on fuels, energies, CARBON DIOXIDE, SO2, etc. To advertise the advancement of biomass energy, to exempt all taxes on biomass projects. In 1991, Sweden federal government begins to lay tax on CO2 discharge, which makes the cost of oil and nonrenewable fuel source rise. So many heat supply center and also power plants changes from nonrenewable fuel source to biomass fuel.



To encourage the nuclear power plant to make use of biomass power, Sweden government introduced electrical power quota system. This policy requires the power suppliers to have certain part of power created by renewable resource. For every single 1MWh electrical power, the government will certainly provide tax obligation alleviation based on the biomass power quantity.



Sweden wood pellet fuel burning gadget

Sweden wood pellet melting modern technology is in the leading placement. There have actually mored than 20 pellet burner suppliers, over 50 types of wood pellet boilers, 120,000 collections of pellet boilers, 20,000 sets of pellet ovens. As there are still many households making use of electric home heating, the pellet boilers have big capacity.



Sweden pellet burning devices has central home heating central heating boiler as well as biomass range 2 kinds.
