Sweden biomass pellet fuel industry analysis<br>
Sweden is among the world's biggest wood pellet fuel producer and consumer. It's wood pellet production innovation, market policy, and market version project. In this passage, I will certainly do detailed analysis on Sweden biomass pellet fuel industry, and work out some beneficial experiences.



Introduction

In the 1970s, several nations have made policies to advertise biomass energy as a means to cope with energy dilemma as well as environment contamination. Since then, biomass energy sector has created swiftly, and also the modern technology keep boosting.



Because of the lack of mineral resources, Sweden's economic situation endured great loss in last century. To ensure national power security, Sweden government make every effort to develop renewable resource.



Biomass pellet fuel has the attributes of high burning performance, low ash web content, no carbon emission, easy transportation, which has been popular in Europe and The United States And Canada. With plentiful forestry sources, Sweden pay much interest to the development of biomass pellet fuel. Sweden occupies 20% of the globe's biomass fuel intake, which grows up at the speed of 8-10%.



Sweden forestry sources and also biomass products

Sweden has abundant forestry resources. The woodland covers 64% of the land area, with 51% possessed by individuals, 24% by huge wood business, and also 25% by countries and also various other public organizations. Besides, the forestry expands by 100 million tons yearly, and also the logging amount is 92.4 million tons. The major forestry industries are wood processing, paper handling, as well as energy wood. The wood products for making biomass energy mainly come from the 3 markets above, concerning 23.48 m3.



Raw materials of wood pellets

Of the raw products for making wood pellets, wood shavings take up 53%, sawdust 35%, and wood chips 5%, others (barks, farming residues, power forestry) takes up 7%. Some little wood pellet factory are built 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 a lot more strong. As the crop straws in Sweden are in scattered circulation, they are hard to accumulate and process. So some producers as well as institutes are creating new products like peat and also power plants.



Wood pellet making innovation and devices

The pellet molding innovation has actually matured in Sweden. Nowadays, it has achieved commercial as well as market production. The manufacturing process features high automation, requiring less operators. The picture below showed the wood pellet manufacturing process.



Drying out: usually, the moisture content of sawdust is around 50%. Richi machine can reduce the dampness content to 9-12% to ensure that it is gotten approved for making pellets.

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

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

Pellet molding: many wood pellet factories make use of vertical kind ring die pellet machine. The manufacturing ability of one equipment 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 are at the temperature of 100 ℃. Pellets under this problem are simple to damage and also troublesome for transport. A counter-flow cooler can cool off the wood pellets in a moderate means.

Packing: the cooled down pellets require to be categorized and also packaged according to clients' need. Tiny bags are 16kg, huge bags are 900kg. For huge customers like power plant, the wood pellets are carried by vehicles and also ships wholesale.

Biomass pellets category and application

In 1999, Sweden federal government released the standard of wood pellet fuel, in which they are identified right into 3 courses. wood pellet machine for home use has premium quality. They can be used in residential little heaters and also stoves.The 2nd as well as 3rd don't have premium quality. They are used by huge industrial clients.



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



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



From the 1970s to the 1990s, Sweden regional heating plant embrace coal to replace oil. After the pass of CO2 exhaust tax obligation, these home heating plant look to biomass fuel from coal. In the last decade, the amount of biomass fuel for heating grows from 1.1 PJ to 57PJ. Currently, about 400 regional home heating plant has taken on wood pellet fuel.



Considering that the mid 1990s, domestic wood pellet sector has actually made wonderful progress. In the last decades, using domestic heating wood pellets proliferates. Presently, Sweden has 200,000 family members utilizing wood pellet boilers, 40,000 families making use of wood pellet ranges.



Sweden biomass energy advancement goal as well as plan

To promote the continuous development of biomass power, Sweden has actually made a collection of legislations and policies. To guarantee the execute of these policies, the federal government additionally made lots of possible supervision actions and also obligatory market criterion.



Sweden not just satisfy the responsibility specified Kyoto Method that reduced greenhouse exhaust by 8%, but likewise set its own growth goal of biomass power. In 2006, the Preacher for lasting growth department asserted that Sweden will totally make use of biofuels as well as stop utilizing oil, and end up being the first nation that completely rely upon renewable resource.



By 2020, Sweden will certainly enhance its percentage of renewable resource to 50%, the use ratio of renewable energy in transport sector to 10%, power efficiency by 20%, and also cut the discharge of greenhouse gas by 40%.



Wood pellet fuel reward policy

Sweden has performed high cost acquisition, financial investment aids, tax reduction and exemption, quota system and other biomass energy motivation policy.



Given that 1975, Sweden spends 36 million Euro from federal government budget 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 supplied 1350 Euros for residents that make use of biomass furnace.



Sweden typically lay high tax obligation on fuels, energies, CO2, SO2, and so on. To promote the advancement of biomass power, to excuse all tax obligations on biomass tasks. In 1991, Sweden government starts to lay tax on carbon dioxide discharge, which makes the price of oil as well as fossil fuel surge. Many warm supply center and also nuclear power plant changes from fossil fuel to biomass fuel.



To motivate the nuclear power plant to make use of biomass energy, Sweden federal government presented electric power quota system. This plan calls for the power suppliers to have particular portion of electrical power created by renewable energy. For each 1MWh electrical power, the federal government will provide tax obligation alleviation based upon the biomass power amount.
