Sweden biomass pellet fuel industry analysis
Sweden biomass pellet fuel industry analysis
Sweden is among the world's biggest wood pellet fuel manufacturer and customer. It's wood pellet production modern technology, market policy, and market version project. In this passage, I will certainly do comprehensive analysis on Sweden biomass pellet fuel industry, and exercise some helpful experiences.

Intro
In the 1970s, numerous countries have made policies to promote biomass power as a way to manage power situation and atmosphere contamination. Since then, biomass energy sector has developed swiftly, as well as the technology maintain boosting.

Due to the lack of mineral resources, Sweden's economic situation experienced terrific loss in last century. To make sure nationwide power protection, Sweden federal government make every effort to establish renewable resource.

Biomass pellet fuel has the attributes of high burning efficiency, low ash material, absolutely no carbon emission, very easy transportation, which has been prominent in Europe as well as The United States And Canada. With bountiful forestry sources, Sweden pay much attention to the growth of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel consumption, which matures at the rate of 8-10%.

Sweden forestry resources and also biomass materials
Sweden has abundant forestry sources. The forest covers 64% of the land area, with 51% possessed by individuals, 24% by large wood firms, and also 25% by nations and also other public organizations. Besides, the forestry grows by 100 million tons each year, and also the deforestation quantity is 92.4 million bunches. The significant forestry sectors are wood processing, paper handling, and also energy wood. The wood products for making biomass energy mainly come from the 3 markets above, regarding 23.48 m3.

Raw materials of wood pellets
Of the raw materials for making wood pellets, wood shavings take up 53%, sawdust 35%, as well as wood chips 5%, others (barks, farming residues, energy forestry) takes up 7%. Some little wood pellet factory are constructed base upon chipboard, furniture and sawdust mills.

With even more companies engaging in biomass fuel production, the competitors on the raw products become a lot more fierce. As the crop straws in Sweden are in scattered distribution, they are hard to collect and refine. So some producers as well as institutes are developing brand-new materials like peat and power plants.

Wood pellet manufacturing technology and also devices
The pellet molding technology has actually grown in Sweden. Nowadays, it has accomplished industrial as well as market manufacturing. The manufacturing procedure includes high automation, needing less drivers. The picture listed below showed the wood pellet production procedure.

Drying: generally, the dampness web content of sawdust is around 50%. A drum clothes dryer can lower the moisture material to 9-12% to make sure that it is received making pellets.
Crushing: the size of raw materials ought to be under 5mm. They need a hammer mill to reduce the size.
Conditioning: include high-heat heavy steam to the raw products and also soften the cellulous in it. Majority of the pellet fuel suppliers have conditioning process in manufacturing.
Pellet molding: many wood pellet factories utilize upright kind ring pass away pellet device. The manufacturing capacity of one device 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 equipment are at the temperature of 100 ℃. Pellets under this condition are very easy to damage and troublesome for transportation. A counter-flow colder can cool the wood pellets in a modest means.
Packaging: the cooled pellets need to be categorized and packaged according to customers' need. Little bags are 16kg, huge bags are 900kg. For big customers like nuclear power plant, the wood pellets are transported by vehicles and also ships wholesale.
Biomass pellets classification and also application
In 1999, Sweden federal government published the standard of wood pellet fuel, in which they are classified right into 3 classes. The extraordinary has premium quality. They can be utilized in residential tiny heaters as well as stoves.The second and also third do not have high quality. They are used by large commercial consumers.

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

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

From the 1970s to the 1990s, Sweden regional heating plant take on coal to change oil. After the establish of CO2 emission tax, these home heating plant resort 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, regarding 400 local heating plant has taken on wood pellet fuel.

Given that the mid 1990s, residential wood pellet market has actually made excellent development. In the last decades, using residential home heating wood pellets proliferates. Presently, Sweden has 200,000 households using wood pellet boilers, 40,000 households utilizing wood pellet stoves.

Sweden biomass power development goal and also policy
To promote the continuous growth of biomass energy, Sweden has actually made a collection of regulations and plans. To guarantee the apply of these plans, the government additionally made numerous viable supervision measures and obligatory industry requirement.

Sweden not only fulfill the obligation stipulated Kyoto Procedure that cut greenhouse emission by 8%, but likewise established its very own development goal of biomass power. In 2006, the Preacher for lasting development department asserted that Sweden will completely use biofuels and also quit making use of oil, as well as come to be the first nation that totally depend on renewable energy.

By 2020, Sweden will certainly boost its proportion of renewable energy to 50%, the use ratio of renewable energy in transport industry to 10%, energy effectiveness by 20%, and also cut the exhaust of greenhouse gas by 40%.

Wood pellet fuel incentive policy
Sweden has performed high cost procurement, investment aids, tax reduction and also exception, quota system and also other biomass energy reward policy.

Considering that 1975, Sweden spends 36 million Euro from government budget plan to support biomass technology advancement. From 1997 to 2002, the government supplied 25% investment aid to biomass cogeneration jobs. From 2004-2006, the federal government gave 1350 Euros for locals who utilize biomass furnace.

Sweden generally lay high tax on fuels, energies, CARBON DIOXIDE, SO2, etc. To promote the advancement of biomass power, to spare all tax obligations on biomass projects. In 1991, Sweden federal government starts to lay tax on carbon dioxide emission, which makes the cost of oil and also nonrenewable fuel source increase. Numerous warm supply facility as well as power plants switches over from fossil fuel to biomass fuel.

To encourage the nuclear power plant to make use of biomass energy, Sweden federal government presented electrical power quota system. This plan calls for the power suppliers to have certain portion of power produced by renewable energy. For every single 1MWh power, the federal government will give tax alleviation based on the biomass power quantity.


Sweden wood pellet fuel shedding device
Sweden wood pellet melting technology remains in the leading setting. There have actually been over 20 pellet heater suppliers, over 50 kinds of wood pellet boilers, 120,000 collections of pellet central heating boilers, 20,000 sets of pellet stoves. As there are still several families making use of electrical home heating, the pellet boilers have big potential.
