Sweden biomass pellet fuel sector analysis<br>
Sweden is among the world's biggest wood pellet fuel producer and customer. It's wood pellet manufacturing modern technology, market plan, and market design project. In this flow, I will do detailed analysis on Sweden biomass pellet fuel industry, and also exercise some helpful experiences.



Intro

In the 1970s, many nations have made policies to promote biomass energy as a method to manage energy dilemma as well as environment pollution. Ever since, biomass power industry has developed swiftly, as well as the technology keep enhancing.



As a result of the absence of mineral sources, Sweden's economic climate endured fantastic loss in last century. To make sure national power safety and security, Sweden government strive to establish renewable energy.



Biomass pellet fuel has the functions of high burning effectiveness, low ash content, zero carbon exhaust, very easy transportation, which has actually been prominent in Europe and also The United States And Canada. With bountiful forestry sources, Sweden pay much focus to the advancement of biomass pellet fuel. Sweden uses up 20% of the globe's biomass fuel usage, which grows up at the rate of 8-10%.



Sweden forestry resources and also biomass materials

Sweden has abundant forestry sources. The woodland covers 64% of the acreage, with 51% possessed by individuals, 24% by large wood companies, and 25% by nations and also various other public companies. Besides, the forestry expands by 100 million lots annually, and also the deforestation quantity is 92.4 million tons. The major forestry sectors are wood processing, paper processing, as well as power wood. The wood materials for making biomass energy mostly come from the 3 markets above, regarding 23.48 m3.



Raw materials of wood pellets

Of the raw products for making wood pellets, wood shavings occupy 53%, sawdust 35%, as well as wood chips 5%, others (barks, farming deposits, power forestry) takes up 7%. Some small wood pellet factory are built base upon chipboard, furnishings as well as sawdust mills.



With more companies taking part in biomass fuel production, the competitors on the raw materials end up being more strong. As the plant straws in Sweden remain in scattered circulation, they are tough to collect and also refine. So some producers as well as institutes are creating brand-new products like peat and power crops.



Wood pellet making technology and also tools

The pellet molding technology has actually matured in Sweden. Nowadays, it has accomplished industrial and market manufacturing. The production process features high automation, requiring much less drivers. The picture below displayed the wood pellet manufacturing process.



Drying: usually, the moisture web content of sawdust is around 50%. A drum clothes dryer can reduce the wetness material to 9-12% to ensure that it is received making pellets.

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

Conditioning: add high-heat vapor to the raw materials and also soften the cellulous in it. Over half of the pellet fuel producers have conditioning process in production.

Pellet molding: the majority of wood pellet manufacturing facilities use upright kind ring pass away pellet device. The manufacturing capability of one maker is 2-4ton/ h. The life span of ring die is 2000-3000h, while the roller can last 1000-1500h.

Cooling: the wood pellets extruded out from the pellet device go to the temperature of 100 ℃. Pellets under this problem are simple to break as well as inconvenient for transport. A counter-flow cooler can cool the wood pellets in a moderate way.


Packing: the cooled down pellets require to be classified and also packaged according to consumers' need. Tiny bags are 16kg, huge bags are 900kg. For large consumers like power plant, the wood pellets are transported by trucks and also ships wholesale.

Biomass pellets category as well as application

In 1999, Sweden government released the requirement of wood pellet fuel, in which they are classified into 3 courses. The first-rate has high quality. They can be used in domestic tiny burners as well as stoves.The 2nd and also third do not have excellent quality. They are utilized by huge commercial customers.



Presently, 57% of the wood pellet fuels in Sweden can meet this requirement. A few of them can fulfill the EU criterion, others are not produced according to this requirement.



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



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



Because the mid 1990s, domestic wood pellet market has made wonderful progression. In biomass wood pellet machine , the use of residential heating wood pellets proliferates. Presently, Sweden has 200,000 households using wood pellet boilers, 40,000 family members utilizing wood pellet ranges.



Sweden biomass energy growth objective as well as policy

To advertise the continuous growth of biomass power, Sweden has actually made a collection of laws as well as plans. To make certain the implement of these policies, the government likewise made lots of practical guidance procedures as well as obligatory industry criterion.



Sweden not just accomplish the obligation stipulated Kyoto Method that cut greenhouse emission by 8%, yet additionally set its own advancement objective of biomass power. In 2006, the Preacher for sustainable growth division asserted that Sweden will completely utilize biofuels and stop making use of oil, as well as come to be the first country that entirely depend on renewable resource.



By 2020, Sweden will raise its proportion of renewable energy to 50%, the use ratio of renewable resource in transport industry to 10%, power efficiency by 20%, as well as reduced the emission of greenhouse gas by 40%.



Wood pellet fuel incentive plan

Sweden has performed high cost purchase, financial investment subsidies, tax decrease and also exception, quota system and various other biomass power incentive plan.



Since 1975, Sweden invests 36 million Euro from federal government spending plan to sustain biomass technology advancement. From feed pellet mill for sale to 2002, the government provided 25% investment aid to biomass cogeneration jobs. From 2004-2006, the federal government gave 1350 Euros for locals that utilize biomass furnace.



Sweden normally lay high tax on fuels, powers, CARBON DIOXIDE, SO2, and so on. To promote the growth of biomass energy, to exempt all taxes on biomass tasks. In 1991, Sweden government starts to lay tax obligation on CO2 exhaust, which makes the rate of oil as well as fossil fuel surge. Many warm supply facility as well as nuclear power plant changes from fossil fuel to biomass fuel.



To urge the power plant to use biomass power, Sweden government introduced electrical power quota system. This plan requires the power vendors to have specific part of power generated by renewable resource. For every 1MWh power, the government will certainly give tax relief based upon the biomass power amount.



Sweden wood pellet fuel shedding gadget

Sweden wood pellet shedding innovation remains in the leading setting. There have mored than 20 pellet burner suppliers, over 50 kinds of wood pellet boilers, 120,000 sets of pellet boilers, 20,000 collections of pellet stoves. As there are still many households making use of electrical heating, the pellet boilers have significant possibility.
