Sweden biomass pellet fuel sector evaluation<br>
Sweden is just one of the world's biggest wood pellet fuel producer and also customer. It's wood pellet production technology, sector policy, and market version are prominent. In this flow, I will do thorough analysis on Sweden biomass pellet fuel sector, and exercise some beneficial experiences.



Introduction

In the 1970s, numerous countries have actually made policies to advertise biomass energy as a way to handle power dilemma and also setting air pollution. Ever since, biomass power industry has created swiftly, and also the technology keep improving.



Because of the lack of mineral sources, Sweden's economic climate experienced wonderful loss in last century. To make certain national power security, Sweden federal government strive to create renewable energy.



Biomass pellet fuel has the attributes of high burning performance, low ash material, absolutely no carbon exhaust, easy transportation, which has actually been popular in Europe as well as North America. With plentiful forestry sources, Sweden pay much interest to the advancement of biomass pellet fuel. Sweden occupies 20% of the globe's biomass fuel intake, which matures at the speed of 8-10%.



Sweden forestry sources and also biomass materials


Sweden has abundant forestry resources. The forest covers 64% of the acreage, with 51% owned by individuals, 24% by large wood firms, and also 25% by nations and other public organizations. Besides, the forestry expands by 100 million bunches every year, and the deforestation amount is 92.4 million lots. The major forestry sectors are wood processing, paper handling, as well as energy wood. The wood materials for making biomass energy mostly come from the 3 markets above, about 23.48 m3.



Basic material of wood pellets

Of the raw products for making wood pellets, wood shavings take up 53%, sawdust 35%, as well as wood chips 5%, others (barks, agriculture residues, power forestry) occupies 7%. Some tiny wood pellet manufacturing facility are constructed base upon chipboard, furnishings as well as sawdust mills.



With more firms taking part in biomass fuel manufacturing, the competitors on the raw materials end up being more tough. As the plant straws in Sweden remain in scattered circulation, they are tough to gather and also process. So some producers as well as institutes are creating new materials like peat as well as energy plants.



Wood pellet producing technology and also devices

The pellet molding modern technology has actually developed in Sweden. Nowadays, it has actually attained industrial and also market manufacturing. The manufacturing process includes high automation, requiring much less drivers. The picture below showed the wood pellet manufacturing process.



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

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

Conditioning: add high-heat steam to the raw materials and soften the cellulous in it. More than half of the pellet fuel producers have conditioning procedure in production.

Pellet molding: a lot of wood pellet manufacturing facilities make use of vertical kind ring pass away pellet maker. The manufacturing 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 machine are at the temperature level of 100 ℃. Pellets under this problem are simple to damage and bothersome for transport. A counter-flow colder can cool off the wood pellets in a modest means.

Packaging: the cooled down pellets require to be classified and also packaged according to consumers' need. Small bags are 16kg, huge bags are 900kg. For big customers like power plant, the wood pellets are delivered by vehicles and also ships wholesale.

Biomass pellets category and also application

In 1999, Sweden government released the standard of wood pellet fuel, in which they are identified right into 3 classes. The extraordinary has high quality. They can be used in residential little burners as well as stoves.The second as well as third do not have excellent quality. They are used by huge commercial clients.



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



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



From the 1970s to the 1990s, Sweden regional heating plant embrace coal to replace oil. After the establish of CO2 discharge tax, 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.



Since the mid 1990s, domestic wood pellet market has actually made great progress. In the last years, using domestic heating wood pellets proliferates. Presently, Sweden has 200,000 family members utilizing wood pellet central heating boilers, 40,000 households using wood pellet cooktops.



Sweden biomass energy growth goal and also plan

To promote the continuous growth of biomass energy, Sweden has made a collection of regulations and policies. To guarantee the execute of these plans, the government additionally made several practical supervision actions and also required industry standard.



Sweden not just meet the commitment stipulated Kyoto Protocol that reduced greenhouse exhaust by 8%, yet also established its very own growth goal of biomass power. In 2006, the Priest for sustainable growth division claimed that Sweden will completely make use of biofuels as well as quit using oil, and end up being the initial country that totally rely on renewable energy.



By 2020, Sweden will boost its proportion of renewable energy to 50%, the usage ratio of renewable energy in transport sector to 10%, energy efficiency by 20%, and also reduced the exhaust of greenhouse gas by 40%.



Wood pellet fuel incentive plan

Sweden has actually executed high rate procurement, investment aids, tax obligation reduction as well as exemption, quota system and also various other biomass power incentive policy.



Given that 1975, Sweden invests 36 million Euro from government spending plan to sustain biomass innovation development. From 1997 to 2002, the federal government supplied 25% financial investment subsidy to biomass cogeneration projects. From 2004-2006, the federal government supplied 1350 Euros for residents that utilize biomass heater.



Sweden normally lay high tax on fuels, energies, CARBON DIOXIDE, SO2, etc. To promote the development of biomass power, to spare all taxes on biomass projects. In 1991, Sweden federal government starts to lay tax on CO2 emission, that makes the rate of oil and fossil fuel surge. Many warm supply center as well as power plants changes from fossil fuel to biomass fuel.



To urge the power plant to make use of biomass power, Sweden federal government introduced electric power quota system. plastic pellet mill requires the power providers to have specific part of power produced by renewable resource. For each 1MWh electrical energy, the federal government will certainly offer tax relief based on the biomass power amount.



Sweden wood pellet fuel melting tool

Sweden wood pellet melting modern technology remains in the leading placement. There have been over 20 pellet heater producers, over 50 sorts of wood pellet central heating boilers, 120,000 sets of pellet boilers, 20,000 collections of pellet stoves. As there are still many families using electric home heating, the pellet central heating boilers have substantial potential.



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




Central heating central heating boiler can be utilized in 1 or even 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 boilers likewise has 2 kinds. The mixed boiler is attached by a pellet burner and a conventional boiler. The central heating boiler can connect with numerous burners. The incorporated boilers are primarily imported from Austria and also Germany, some generated by residential manufacturers.



Biomass cooktops or heater

Biomass ovens additionally has 2 types. Independent pellet oven as well as Smokeshaft item type furnace. The former on is much more preferred. The independent pellet oven has a pellet supply bin within, which can hold wood pellets for 2-day use.



Biomass pellet stove can realize automated filling and also burning. Based on different feeding approach, pellet ovens has leading feed, lower feed and also straight feed 3 types. Leading feed pellet ovens are one of the most popular. Owing to high benefit and cleanliness, small pellet stoves sell well over the last few years.
