Sweden biomass pellet fuel market evaluation<br>
Sweden is one of the globe's biggest wood pellet fuel manufacturer as well as customer. It's wood pellet production innovation, sector plan, and market design project. In this flow, I will certainly do comprehensive analysis on Sweden biomass pellet fuel industry, as well as work out some helpful experiences.



Introduction

In the 1970s, numerous countries have made plans to promote biomass power as a method to deal with energy situation and also environment air pollution. Since then, biomass power industry has established swiftly, and also the technology maintain improving.



Because of the absence of mineral sources, Sweden's economy experienced excellent loss in last century. To make sure national energy security, Sweden government make every effort to create renewable resource.



Biomass pellet fuel has the functions of high burning efficiency, low ash web content, no carbon discharge, very easy transportation, which has actually been popular in Europe as well as North America. With bountiful forestry resources, Sweden pay much interest to the growth of biomass pellet fuel. richi machinery uses up 20% of the world's biomass fuel usage, which grows up at the rate of 8-10%.



Sweden forestry sources and also biomass products

Sweden has bountiful forestry sources. The forest covers 64% of the acreage, with 51% possessed by individuals, 24% by huge wood companies, and 25% by nations and various other public companies. Besides, the forestry grows by 100 million loads every year, as well as the logging amount is 92.4 million bunches. The major forestry markets are wood handling, paper processing, as well as energy wood. The wood materials for making biomass power mostly originated from the 3 industries above, concerning 23.48 m3.



Resources of wood pellets

Of the raw products for making wood pellets, wood shavings use up 53%, sawdust 35%, as well as wood chips 5%, others (barks, agriculture deposits, power forestry) takes up 7%. Some little wood pellet factory are constructed base upon chipboard, furniture and also sawdust mills.



With even more firms participating in biomass fuel manufacturing, the competition on the raw materials become a lot more tough. As the plant straws in Sweden remain in scattered distribution, they are tough to gather and process. So some producers and also institutes are developing new materials like peat and also energy crops.



Wood pellet manufacturing technology as well as devices

The pellet molding innovation has developed in Sweden. Nowadays, it has attained industrial and market manufacturing. The production process includes high automation, needing less drivers. The picture listed below showed the wood pellet production process.



Drying: generally, the moisture web content of sawdust is around 50%. A drum dryer can lower the wetness content to 9-12% to ensure that it is qualified for making pellets.

Crushing: the dimension of resources should be under 5mm. They require a hammer mill to decrease the size.

Conditioning: include high-heat steam to the raw products and also soften the cellulous in it. More than half of the pellet fuel suppliers have conditioning procedure in manufacturing.

Pellet molding: most wood pellet factories make use of vertical kind ring pass away pellet device. The production capability of one device 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 device are at the temperature of 100 ℃. Pellets under this condition are easy to damage as well as inconvenient for transport. A counter-flow colder can cool off the wood pellets in a modest means.

Packing: the cooled down pellets need to be classified and packaged according to clients' need. Little bags are 16kg, large bags are 900kg. For big consumers like nuclear power plant, the wood pellets are carried by vehicles and also ships wholesale.

Biomass pellets classification as well as application

In 1999, Sweden government published the standard of wood pellet fuel, in which they are classified into 3 courses. The extraordinary has premium quality. They can be used in residential little burners and also stoves.The 2nd as well as third don't 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. A few of them can satisfy the EU criterion, others are not produced according to this requirement.



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



From the 1970s to the 1990s, Sweden local heating plant embrace coal to replace oil. After the enact 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. Currently, about animal pellet machine heating plant has actually taken on wood pellet fuel.



Given that the mid 1990s, residential wood pellet industry has made wonderful progression. In the last years, making use of domestic home heating wood pellets grows rapidly. Presently, Sweden has 200,000 households utilizing wood pellet central heating boilers, 40,000 family members utilizing wood pellet ovens.



Sweden biomass energy growth goal and policy

To promote the continual development of biomass power, Sweden has actually made a series of laws and also plans. To make certain the carry out of these plans, the federal government additionally made several possible guidance steps and also necessary market standard.



Sweden not only fulfill the responsibility specified Kyoto Protocol that reduced greenhouse exhaust by 8%, but likewise established its own growth objective of biomass energy. In 2006, the Priest for sustainable growth department claimed that Sweden will totally utilize biofuels as well as stop utilizing oil, and end up being the initial nation that totally count on renewable energy.



By 2020, Sweden will certainly boost its proportion of renewable energy to 50%, the usage ratio of renewable resource in transport market to 10%, energy efficiency by 20%, as well as reduced the discharge of greenhouse gas by 40%.




Wood pellet fuel incentive plan

Sweden has actually executed high cost purchase, investment subsidies, tax obligation decrease and exception, quota system as well as various other biomass energy incentive plan.



Considering that 1975, Sweden invests 36 million Euro from federal government budget plan to support biomass innovation development. From 1997 to 2002, the federal government provided 25% investment aid to biomass cogeneration jobs. From 2004-2006, the government provided 1350 Euros for locals that make use of biomass heating unit.



Sweden generally lay high tax on fuels, energies, CO2, SO2, and so on. To promote the growth of biomass power, to spare all taxes on biomass jobs. In 1991, Sweden federal government starts to lay tax obligation on CO2 discharge, that makes the rate of oil as well as fossil fuel increase. So many heat supply facility as well as power plants changes from fossil fuel to biomass fuel.



To urge the power plant to make use of biomass power, Sweden government presented electric power quota system. This plan calls for the power suppliers to have particular section of power generated by renewable resource. For every single 1MWh electrical power, the government will certainly offer tax obligation alleviation based upon the biomass power amount.



Sweden wood pellet fuel melting gadget

Sweden wood pellet shedding technology is in the leading placement. There have been over 20 pellet burner producers, over 50 sorts of wood pellet boilers, 120,000 collections of pellet central heating boilers, 20,000 sets of pellet stoves. As there are still many households making use of electric home heating, the pellet boilers have significant capacity.



Sweden pellet burning devices has central heating central heating boiler as well as biomass cooktop 2 types.



Central home heating boiler can be made use of in 1 or even more family members. The thermal transfer with water. The powers are 10-40kw, which can be changed by 30% -100% according to demands. The main heating boilers also has 2 kinds. The consolidated boiler is linked by a pellet burner as well as a basic central heating boiler. The boiler can get in touch with numerous burners. The integrated boilers are generally imported from Austria and also Germany, some produced by residential producers.



Biomass ovens or heating system

Biomass ranges additionally has 2 types. Independent pellet cooktop and also Smokeshaft item type heating system. The previous on is much more preferred. The independent pellet cooktop has a pellet supply container inside, which can hold wood pellets for 2-day use.



Biomass pellet cooktop can understand automatic filling and burning. Based on various feeding approach, pellet ranges has top feed, lower feed and also straight feed 3 kinds. Top feed pellet cooktops are the most preferred. Owing to high ease as well as sanitation, little pellet cooktops sell well in the last few years.



Features of Sweden biomass fuel market

Sweden has rich forestry resources as well as bountiful forestry waste, which become the main raw materials for biomass pellets.

Sweden wood pellet sector has been totally commercialized. The majority of producers are large and medium firms, with fully grown technology. Tiny wood pellet factories are mostly build on chipboard, furniture and saw mills.

The government has made detailed regulations and also policies to drive the wood pellet production. This is why the wood pellet market develops quickly considering that the 1990s.
