Sweden biomass pellet fuel sector analysis<br>
Sweden is just one of the globe's largest wood pellet fuel producer and also consumer. It's wood pellet manufacturing technology, industry plan, as well as market model project. In this flow, I will certainly do thorough evaluation on Sweden biomass pellet fuel market, and also work out some helpful experiences.



Intro

In the 1970s, lots of countries have made plans to promote biomass energy as a way to handle energy dilemma as well as setting pollution. Since then, biomass power sector has actually established rapidly, as well as the innovation keep enhancing.



As a result of the lack of mineral resources, Sweden's economy experienced wonderful loss in last century. To guarantee national energy security, Sweden federal government aim to establish renewable energy.



Biomass pellet fuel has the functions of high burning performance, reduced ash content, no carbon exhaust, easy transport, which has actually been prominent in Europe as well as The United States And Canada. With plentiful forestry resources, Sweden pay much interest to the growth of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel usage, which grows up at the rate of 8-10%.



Sweden forestry resources as well as biomass materials

Sweden has plentiful forestry sources. The forest covers 64% of the acreage, with 51% owned by individuals, 24% by large wood business, and also 25% by countries as well as various other public companies. Besides, the forestry grows by 100 million loads each year, and the logging amount is 92.4 million tons. The significant forestry sectors are wood handling, paper handling, as well as energy wood. The wood products 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, farming deposits, power forestry) occupies 7%. Some little wood pellet factory are developed base on chipboard, furnishings and also sawdust mills.



With more companies engaging in biomass fuel production, the competition on the raw products end up being more tough. As the plant straws in Sweden remain in scattered circulation, they are tough to collect as well as process. So some producers and also institutes are establishing new products like peat and energy crops.



Wood pellet producing technology as well as equipment

The pellet molding innovation has actually developed in Sweden. Nowadays, it has achieved commercial and also market production. The production procedure includes high automation, requiring less operators. The picture listed below showed the wood pellet production process.



Drying out: normally, the wetness material of sawdust is around 50%. A drum dryer can reduce the wetness material to 9-12% so that it is qualified for making pellets.

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

Conditioning: include high-heat steam to the raw materials and also soften the cellulous in it. floating feed making machine of the pellet fuel manufacturers have conditioning procedure in manufacturing.

Pellet molding: many wood pellet manufacturing facilities make use of vertical type ring die pellet machine. The production ability of one machine 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 maker are at the temperature level of 100 ℃. Pellets under this problem are simple to break and also inconvenient for transport. A counter-flow colder can cool down the wood pellets in a moderate way.

Packing: the cooled pellets need to be classified and packaged according to consumers' demand. Little bags are 16kg, large bags are 900kg. For large customers like power plant, the wood pellets are transferred by trucks as well as ships wholesale.

Biomass pellets category and application

In 1999, Sweden federal government published the requirement of wood pellet fuel, in which they are identified into 3 courses. The first class has premium quality. They can be made use of in domestic little heaters as well as stoves.The second as well as 3rd don't have high quality. They are used by big commercial consumers.



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



Wood pellet fuel can be applied in tiny central heating boilers, medium-scale as well as large-scale home heating supply facility and nuclear power plant. Currently, 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 center and co-firing power plant.



From the 1970s to the 1990s, Sweden regional heating plant embrace coal to replace oil. After the establish of carbon dioxide emission tax obligation, these heating plant turn to biomass fuel from coal. In the last years, the amount of biomass fuel for home heating expands from 1.1 PJ to 57PJ. Currently, about 400 regional heating plant has embraced wood pellet fuel.



Considering that the mid 1990s, domestic wood pellet market has actually made fantastic development. In the last decades, the use of domestic home heating wood pellets grows rapidly. Presently, Sweden has 200,000 families using wood pellet boilers, 40,000 households utilizing wood pellet stoves.



Sweden biomass power development objective as well as plan

To promote the continuous growth of biomass energy, Sweden has actually made a series of legislations and policies. To guarantee the implement of these policies, the federal government likewise made numerous viable supervision steps as well as necessary sector standard.



Sweden not just meet the responsibility stated Kyoto Procedure that cut greenhouse exhaust by 8%, however additionally established its very own growth goal of biomass energy. In 2006, the Minister for lasting advancement department declared that Sweden will totally make use of biofuels and also quit utilizing oil, and come to be the initial country that completely rely upon renewable energy.



By 2020, Sweden will certainly boost its percentage of renewable energy to 50%, the usage proportion of renewable resource in transportation industry to 10%, energy effectiveness by 20%, and reduced the exhaust of greenhouse gas by 40%.



Wood pellet fuel motivation plan

Sweden has accomplished high rate acquisition, investment aids, tax obligation decrease and exception, quota system and also various other biomass power reward policy.



Because 1975, Sweden invests 36 million Euro from government budget to sustain biomass modern technology advancement. From 1997 to 2002, the federal government supplied 25% investment aid to biomass cogeneration projects. From 2004-2006, the federal government provided 1350 Euros for residents that utilize biomass heating unit.



Sweden normally lay high tax obligation on fuels, energies, CARBON DIOXIDE, SO2, etc. To advertise the advancement of biomass energy, to excuse all taxes on biomass tasks. In 1991, Sweden federal government starts to lay tax obligation on CO2 exhaust, that makes the rate of oil and fossil fuel increase. So many heat supply center and also nuclear power plant switches from fossil fuel to biomass fuel.



To urge the power plant to use biomass energy, Sweden government introduced electric power quota system. This policy calls for the power providers to have certain part of power generated by renewable resource. For each 1MWh electrical power, the government will provide tax alleviation based on the biomass power quantity.



Sweden wood pellet fuel melting gadget

Sweden wood pellet shedding innovation is in the leading placement. There have actually been over 20 pellet burner manufacturers, over 50 sorts of wood pellet boilers, 120,000 collections of pellet boilers, 20,000 collections of pellet ovens. As there are hemp pellet mill utilizing electrical home heating, the pellet boilers have significant potential.



Sweden pellet burning tools has main heating central heating boiler as well as biomass stove 2 kinds.



Central home heating central heating boiler can be used in 1 or more households. The thermal transfer with water. The powers are 10-40kw, which can be adjusted by 30% -100% according to needs. The main heating central heating boilers likewise has 2 kinds. The mixed boiler is attached by a pellet heater and also a common central heating boiler. The boiler can get in touch with various burners. The integrated boilers are primarily imported from Austria and Germany, some created by residential manufacturers.



Biomass ranges or heating system

Biomass ranges additionally has 2 types. Independent pellet cooktop as well as Chimney piece type furnace. The previous on is much more prominent. The independent pellet range has a pellet stock container inside, which can hold wood pellets for 2-day use.



Biomass pellet cooktop can understand automated filling as well as burning. Based on different feeding method, pellet ranges has top feed, bottom feed and also horizontal feed 3 kinds. Top feed pellet cooktops are one of the most popular. Owing to high benefit as well as tidiness, little pellet stoves sell well recently.



Functions of Sweden biomass fuel market

Sweden has rich forestry sources as well as bountiful forestry waste, which become the primary basic materials for biomass pellets.

Sweden wood pellet sector has been completely advertised. The majority of producers are huge as well as moderate business, with mature innovation. Small wood pellet manufacturing facilities are mainly build on chipboard, furnishings and saw mills.

The federal government has actually made extensive legislations as well as plans to drive the wood pellet production. This is why the wood pellet sector establishes quickly because the 1990s.


Standard for wood pellet fuel maintain improving. In the 1990s, Sweden published the requirement for wood pellets, and also measured the technique day of pellet fuel and also burners.

Fully grown burning innovation and also devices. In the last few years, Sweden's production of pellet central heating boiler and also pellet home heating ranges keep raising.

Perfect quality control system. Sweden government stipulated that the wood pellet fuel and burning tools must obtain third-party screening accreditations before entering the market.




Final thought

Sweden is a significant wood pellet fuel manufacturer as well as consumer on the planet. Biomass energy plays an essential function in its manufacturing and lifestyle.
