Sweden biomass pellet fuel sector evaluation<br>
Sweden is just one of the world's largest wood pellet fuel manufacturer as well as consumer. It's wood pellet production modern technology, market policy, and market design project. In this passage, I will certainly do detailed analysis on Sweden biomass pellet fuel market, as well as exercise some beneficial experiences.



Intro

In the 1970s, lots of countries have actually made plans to advertise biomass energy as a means to handle energy situation as well as setting air pollution. Since then, biomass energy market has developed quickly, and the technology keep boosting.



As a result of the absence of mineral resources, Sweden's economic climate suffered wonderful loss in last century. To make sure national energy security, Sweden government aim to establish renewable resource.



Biomass pellet fuel has the attributes of high burning efficiency, low ash content, absolutely no carbon emission, very easy transport, which has been popular in Europe and also The United States And Canada. With plentiful forestry sources, Sweden pay much focus to the advancement of biomass pellet fuel. Sweden occupies 20% of the globe's biomass fuel consumption, which grows up at the rate of 8-10%.



Sweden forestry sources and also biomass products

Sweden has abundant forestry sources. The woodland covers 64% of the land area, with 51% possessed by people, 24% by big wood companies, and 25% by countries and also various other public companies. Besides, the forestry expands by 100 million bunches each year, and the logging amount is 92.4 million bunches. The major forestry industries are wood processing, paper processing, as well as energy wood. The wood materials for making biomass energy primarily come from the 3 markets above, regarding 23.48 m3.



Basic material of wood pellets

Of the raw products for making wood pellets, wood shavings use up 53%, sawdust 35%, and wood chips 5%, others (barks, farming residues, energy forestry) takes up 7%. Some little wood pellet factory are built base on chipboard, furnishings as well as sawdust mills.




With even more business engaging in biomass fuel manufacturing, the competition on the raw products come to be a lot more strong. As the plant straws in Sweden are in scattered distribution, they are hard to gather and refine. So biomass pellet mill for sale as institutes are establishing new products like peat and energy plants.



Wood pellet making modern technology and also equipment

The pellet molding modern technology has grown in Sweden. Nowadays, it has achieved commercial and market production. The production procedure includes high automation, requiring much less drivers. The picture below showed the wood pellet production 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 gotten approved for making pellets.

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

Conditioning: include high-heat steam to the raw materials as well as soften the cellulous in it. Over half of the pellet fuel manufacturers have conditioning procedure in manufacturing.

Pellet molding: most wood pellet manufacturing facilities make use of upright kind ring pass away pellet device. The production capability of one device 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 machine are at the temperature of 100 ℃. Pellets under this problem are very easy to break and troublesome for transport. A counter-flow cooler can cool off the wood pellets in a modest method.

Packaging: the cooled down pellets need to be categorized and packaged according to consumers' need. Tiny bags are 16kg, large bags are 900kg. For big consumers like nuclear power plant, the wood pellets are transported by trucks as well as ships in bulks.

Biomass pellets classification and also application

In 1999, Sweden federal government published the requirement of wood pellet fuel, in which they are identified into 3 classes. The first-rate has high quality. They can be made use of in residential small heaters and stoves.The second and also third don't have high quality. They are utilized by huge industrial clients.



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



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



From the 1970s to the 1990s, Sweden local heating plant embrace coal to change oil. After the enact of CO2 discharge tax obligation, these home heating plant resort to biomass fuel from coal. In the last years, the amount of biomass fuel for home heating expands from 1.1 PJ to 57PJ. Presently, concerning 400 local heating plant has adopted wood pellet fuel.



Considering that the mid 1990s, residential wood pellet sector has actually made fantastic development. In the last decades, using domestic heating wood pellets proliferates. Presently, Sweden has 200,000 households making use of wood pellet boilers, 40,000 households using wood pellet ovens.



Sweden biomass power development objective and plan

To promote the continual development of biomass energy, Sweden has actually made a collection of regulations and also plans. To make certain the carry out of these policies, the government also made many practical supervision actions and also mandatory sector standard.



Sweden not only satisfy the responsibility specified Kyoto Procedure that cut greenhouse emission by 8%, however likewise set its very own growth goal of biomass power. In 2006, the Priest for lasting growth division declared that Sweden will totally utilize biofuels and also stop making use of oil, and become the very first nation that entirely rely upon renewable energy.



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



Wood pellet fuel motivation plan

Sweden has executed high rate acquisition, financial investment subsidies, tax obligation reduction and exception, quota system and also various other biomass energy reward policy.



Since 1975, Sweden spends 36 million Euro from federal government budget plan to sustain biomass technology growth. From 1997 to 2002, the government provided 25% financial investment subsidy to biomass cogeneration tasks. From 2004-2006, the government offered 1350 Euros for citizens that make use of biomass heating unit.



Sweden generally lay high tax on fuels, powers, CARBON DIOXIDE, SO2, and so on. To advertise the advancement of biomass energy, to spare all taxes on biomass jobs. In 1991, Sweden government starts to lay tax obligation on carbon dioxide discharge, that makes the cost of oil as well as nonrenewable fuel source surge. A lot of warmth supply facility as well as nuclear power plant changes from nonrenewable fuel source to biomass fuel.



To urge the nuclear power plant to make use of biomass energy, Sweden government introduced electrical power quota system. This plan calls for the power suppliers to have specific part of power produced by renewable resource. For every single 1MWh electrical power, the government will give tax obligation relief based on the biomass power amount.



Sweden wood pellet fuel shedding tool

Sweden wood pellet melting innovation is in the leading position. There have mored than 20 pellet burner makers, over 50 sorts of wood pellet central heating boilers, 120,000 collections of pellet central heating boilers, 20,000 sets of pellet ovens. As there are still numerous families using electrical heating, the pellet central heating boilers have significant possibility.



Sweden pellet burning tools has central home heating central heating boiler and also biomass stove 2 types.



Central heating central heating boiler can be used in 1 or more families. The thermal transfer with water. The powers are 10-40kw, which can be adjusted by 30% -100% according to requirements. The main heating central heating boilers additionally has 2 kinds. The combined central heating boiler is connected by a pellet heater and also a typical central heating boiler. The central heating boiler can get in touch with different heaters. wood pellet press incorporated central heating boilers are primarily imported from Austria as well as Germany, some generated by residential suppliers.



Biomass stoves or heater

Biomass ranges additionally has 2 types. Independent pellet oven as well as Smokeshaft item kind furnace. The previous on is more popular. The independent pellet oven has a pellet supply bin inside, which can hold wood pellets for 2-day use.



Biomass pellet oven can recognize automatic filling and burning. Based upon various feeding technique, pellet stoves has leading feed, bottom feed and also horizontal feed 3 types. Leading feed pellet stoves are one of the most preferred. Owing to high convenience and also cleanliness, little pellet ranges offer well recently.



Attributes of Sweden biomass fuel industry

Sweden has abundant forestry resources and bountiful forestry waste, which end up being the main basic materials for biomass pellets.

Sweden wood pellet industry has actually been completely advertised. Most suppliers are big and moderate companies, with fully grown innovation. Tiny wood pellet manufacturing facilities are mostly build on chipboard, furnishings and saw mills.

The federal government has actually made thorough laws and also policies to drive the wood pellet production. This is why the wood pellet sector establishes quickly considering that the 1990s.

Requirement for wood pellet fuel keep boosting. In the 1990s, Sweden released the standard for wood pellets, and determined the method date of pellet fuel and burners.

Fully grown burning technology and equipment. Recently, Sweden's production of pellet boiler and also pellet heating ovens keep enhancing.


Perfect quality assurance system. Sweden government specified that the wood pellet fuel as well as burning devices have to obtain third-party testing certifications prior to getting in the marketplace.



Final thought
