Sweden biomass pellet fuel market evaluation<br>
Sweden is one of the globe's largest wood pellet fuel producer and consumer. It's wood pellet manufacturing innovation, industry plan, as well as market version are prominent. In this passage, I will do extensive analysis on Sweden biomass pellet fuel sector, and exercise some useful experiences.



Intro

In the 1970s, several countries have made plans to promote biomass power as a method to cope with energy situation and setting air pollution. Since then, biomass power sector has established rapidly, and also the technology maintain boosting.



As a result of the lack of mineral resources, Sweden's economy endured fantastic loss in last century. To make sure national energy safety, Sweden government aim to establish renewable resource.



Biomass pellet fuel has the attributes of high burning performance, reduced ash material, no carbon discharge, simple transport, which has actually been popular in Europe and The United States And Canada. With richi machinery , Sweden pay much interest to the development of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel consumption, which grows up at the speed of 8-10%.



Sweden forestry resources and also biomass materials

Sweden has abundant forestry resources. The woodland covers 64% of the land area, with 51% had by people, 24% by huge wood firms, as well as 25% by nations as well as other public companies. Besides, the forestry grows by 100 million lots annually, and the deforestation amount is 92.4 million heaps. The major forestry industries are wood handling, paper handling, as well as energy wood. The wood products for making biomass power generally come from the 3 sectors above, regarding 23.48 m3.



Basic material of wood pellets

Of the raw materials for making wood pellets, wood shavings use up 53%, sawdust 35%, as well as wood chips 5%, others (barks, farming deposits, power forestry) takes up 7%. Some little wood pellet manufacturing facility are constructed base on chipboard, furnishings and also sawdust mills.



With even more firms engaging in biomass fuel production, the competitors on the raw products come to be much more fierce. As the plant straws in Sweden remain in scattered distribution, they are tough to collect and also refine. So some manufacturers and also institutes are creating brand-new materials like peat as well as energy crops.



Wood pellet manufacturing innovation and also tools

The pellet molding modern technology has developed in Sweden. Nowadays, it has actually accomplished business and market manufacturing. The production process includes high automation, needing less drivers. The picture listed below presented the wood pellet manufacturing procedure.



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

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

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

Pellet molding: many wood pellet factories utilize upright type ring die pellet equipment. 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.


Air conditioning: the wood pellets extruded out from the pellet device go to the temperature of 100 ℃. Pellets under this problem are easy to damage as well as inconvenient for transportation. A counter-flow colder can cool the wood pellets in a modest way.

Packing: the cooled pellets need to be identified and also packaged according to clients' requirement. Little bags are 16kg, big bags are 900kg. For large customers like nuclear power plant, the wood pellets are transported by vehicles as well as ships wholesale.

Biomass pellets classification as well as application

In 1999, Sweden federal government released the standard of wood pellet fuel, in which they are identified into 3 courses. The excellent has premium quality. They can be utilized in residential tiny heaters and also stoves.The second and also third do not have top quality. They are used by big industrial clients.



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



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



From the 1970s to the 1990s, Sweden local home heating plant take on coal to change oil. After the pass of CO2 discharge tax, these heating plant look to biomass fuel from coal. In the last years, the amount of biomass fuel for heating grows from 1.1 PJ to 57PJ. Presently, about 400 regional heating plant has taken on wood pellet fuel.



Since the mid 1990s, domestic wood pellet sector has actually made terrific progression. In the last years, using residential home heating wood pellets grows rapidly. Presently, Sweden has 200,000 family members making use of wood pellet boilers, 40,000 families utilizing wood pellet cooktops.



Sweden biomass energy growth objective and plan

To promote the constant growth of biomass energy, Sweden has made a collection of regulations and also policies. To ensure the implement of these policies, the federal government also made lots of feasible guidance measures and also necessary industry criterion.



Sweden not only fulfill the obligation specified Kyoto Method that cut greenhouse exhaust by 8%, however additionally set its very own growth objective of biomass power. In 2006, the Preacher for lasting advancement department declared that Sweden will entirely utilize biofuels as well as stop making use of oil, as well as end up being the first country that completely rely upon renewable resource.



By 2020, Sweden will increase its proportion of renewable energy to 50%, the usage ratio of renewable energy in transport market to 10%, power efficiency by 20%, and also cut the discharge of greenhouse gas by 40%.



Wood pellet fuel motivation policy

Sweden has actually executed high cost acquisition, financial investment subsidies, tax decrease and also exception, quota system and also various other biomass energy reward plan.



Given that 1975, Sweden spends 36 million Euro from federal government spending plan to sustain biomass technology advancement. From 1997 to 2002, the government supplied 25% investment aid to biomass cogeneration jobs. From 2004-2006, the federal government provided 1350 Euros for residents who use biomass heating unit.



Sweden normally lay high tax obligation on fuels, energies, CO2, SO2, and so on. To advertise the advancement of biomass energy, to spare all tax obligations on biomass jobs. In 1991, Sweden government starts to lay tax on carbon dioxide exhaust, that makes the cost of oil as well as fossil fuel rise. So many heat supply facility and also nuclear power plant changes from nonrenewable fuel source to biomass fuel.



To encourage the power plant to use biomass energy, Sweden government introduced electrical power quota system. This policy needs the power providers to have specific part of electrical power generated by renewable energy. For every 1MWh electrical energy, the federal government will certainly provide tax alleviation based upon the biomass power amount.



Sweden wood pellet fuel melting gadget

Sweden wood pellet melting technology remains in the leading setting. There have actually been over 20 pellet burner makers, over 50 sorts of wood pellet boilers, 120,000 collections of pellet central heating boilers, 20,000 collections of pellet cooktops. As there are still numerous family members utilizing electrical heating, the pellet central heating boilers have significant capacity.



Sweden pellet burning equipment has central heating central heating boiler and also biomass oven 2 kinds.



Central heating central heating boiler can be made use of in 1 or even more family members. The thermal transmit with water. The powers are 10-40kw, which can be changed by 30% -100% according to needs. The central home heating central heating boilers also has 2 types. The mixed central heating boiler is linked by a pellet heater as well as a basic boiler. The central heating boiler can get in touch with different burners. The integrated boilers are mainly imported from Austria as well as Germany, some created by residential producers.



Biomass stoves or heater

Biomass ovens also has 2 types. Independent pellet stove as well as Smokeshaft item type furnace. The former on is much more popular. The independent pellet stove has a pellet stock container within, which can hold wood pellets for 2-day use.



Biomass pellet range can understand automated filling and also burning. Based upon different feeding method, pellet stoves has top feed, bottom feed as well as horizontal feed 3 types. Leading feed pellet stoves are the most prominent. Owing to high benefit and also sanitation, small pellet ranges offer well in the last few years.



Functions of Sweden biomass fuel sector

Sweden has rich forestry sources and also abundant forestry waste, which come to be the primary basic materials for biomass pellets.

Sweden wood pellet industry has been totally marketed. A lot of suppliers are huge and medium companies, with fully grown innovation. Little wood pellet manufacturing facilities are mostly improve chipboard, furniture and saw mills.

The government has made comprehensive laws and also plans to drive the wood pellet manufacturing. This is why the wood pellet market creates swiftly since the 1990s.

Requirement for wood pellet fuel keep improving. In richi pellet machine , Sweden released the standard for wood pellets, and gauged the method date of pellet fuel as well as burners.

Mature burning technology and devices. Over the last few years, Sweden's production of pellet central heating boiler and also pellet home heating cooktops keep boosting.

Perfect quality assurance system. Sweden government stated that the wood pellet fuel and burning equipment must get third-party screening certifications prior to going into the market.



Final thought

Sweden is a significant wood pellet fuel producer and consumer in the world. Biomass energy plays an essential duty in its production as well as way of living. Worldwide, biomass pellets are mosting likely to play a more crucial function in heating supply, power generation, and also commercial manufacturing.
