Sweden biomass pellet fuel industry analysis<br>
Sweden is just one of the globe's largest wood pellet fuel manufacturer as well as customer. It's wood pellet production innovation, market plan, and market design are prominent. In this flow, I will certainly do detailed evaluation on Sweden biomass pellet fuel sector, as well as work out some valuable experiences.



Intro

In the 1970s, numerous countries have actually made plans to advertise biomass power as a method to cope with energy situation as well as environment air pollution. Since then, biomass energy sector has established rapidly, as well as the technology maintain boosting.



As a result of the lack of mineral resources, Sweden's economy endured excellent loss in last century. To make sure national energy safety and security, Sweden government strive to create renewable energy.



Biomass pellet fuel has the features of high burning performance, reduced ash material, zero carbon discharge, easy transport, which has been prominent in Europe and also North America. With plentiful forestry sources, Sweden pay much focus to the growth of biomass pellet fuel. Sweden takes up 20% of the globe's biomass fuel consumption, which matures at the speed of 8-10%.



Sweden forestry resources and biomass materials

Sweden has abundant forestry resources. The woodland covers 64% of the land area, with 51% owned by individuals, 24% by big wood companies, and 25% by nations and also other public organizations. Besides, the forestry expands by 100 million tons yearly, and also the deforestation amount is 92.4 million lots. The significant forestry industries are wood processing, paper processing, and also power wood. The wood materials for making biomass power primarily come from the 3 sectors above, regarding 23.48 m3.



Resources of wood pellets

Of the raw products for making wood pellets, wood shavings take up 53%, sawdust 35%, and wood chips 5%, others (barks, agriculture deposits, power forestry) occupies 7%. Some tiny wood pellet factory are developed base upon chipboard, furniture and sawdust mills.



With even more firms engaging in biomass fuel production, the competitors on the raw materials become much more intense. As the crop straws in Sweden remain in scattered distribution, they are difficult to gather and also process. So some manufacturers and also institutes are creating brand-new products like peat as well as energy plants.



Wood pellet making modern technology and equipment


The pellet molding technology has grown in Sweden. Nowadays, it has actually achieved industrial as well as market production. The manufacturing procedure includes high automation, requiring much less drivers. The picture listed below showed the wood pellet production process.



Drying: generally, the wetness material of sawdust is around 50%. A drum clothes dryer can decrease the wetness web content to 9-12% to make sure that it is received making pellets.

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

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

Pellet molding: many wood pellet manufacturing facilities utilize upright type ring pass away pellet machine. The manufacturing capacity of one equipment 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 go to the temperature level of 100 ℃. Pellets under this problem are simple to break and troublesome for transportation. A counter-flow cooler can cool down the wood pellets in a modest method.

Packing: the cooled pellets need to be classified and also packaged according to clients' requirement. Small bags are 16kg, large bags are 900kg. For huge clients like nuclear power plant, the wood pellets are transferred by trucks and also ships wholesale.

Biomass pellets category and also application

In 1999, Sweden government released the criterion of wood pellet fuel, in which they are categorized right into 3 courses. The fabulous has excellent quality. They can be used in residential tiny heaters as well as stoves.The second and third do not have high quality. They are made use of by large commercial customers.



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



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



From the 1970s to the 1990s, Sweden local heating plant adopt coal to change oil. After the pass of carbon dioxide discharge tax obligation, these heating plant count on biomass fuel from coal. In the last decade, the quantity of biomass fuel for heating expands from 1.1 PJ to 57PJ. Presently, concerning 400 regional home heating plant has adopted wood pellet fuel.



Considering that the mid 1990s, residential wood pellet industry has made terrific development. In the last decades, the use of residential heating wood pellets grows rapidly. Currently, richi pellet machine has 200,000 families making use of wood pellet boilers, 40,000 households using wood pellet stoves.



Sweden biomass energy advancement goal and plan

To promote the continuous development of biomass energy, Sweden has actually made a collection of legislations and also plans. To make sure the apply of these policies, the federal government additionally made many possible supervision steps and necessary market standard.



Sweden not just fulfill the responsibility stipulated Kyoto Protocol that cut greenhouse emission by 8%, but likewise set its very own advancement objective of biomass power. In 2006, the Priest for lasting growth division claimed that Sweden will completely make use of biofuels and stop using oil, and end up being the initial country that entirely rely on renewable resource.



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



Wood pellet fuel incentive policy

Sweden has actually performed high price acquisition, financial investment aids, tax obligation decrease and exception, quota system as well as other biomass power incentive plan.



Since 1975, Sweden invests 36 million Euro from government spending plan to sustain biomass modern technology advancement. From 1997 to 2002, the federal government gave 25% financial investment subsidy to biomass cogeneration tasks. From 2004-2006, the government provided 1350 Euros for homeowners that utilize biomass heating unit.




Sweden generally lay high tax on fuels, energies, CO2, SO2, etc. To promote rabbit pellet making machine of biomass power, to spare all taxes on biomass jobs. In 1991, Sweden government begins to lay tax on CO2 discharge, which makes the cost of oil and also nonrenewable fuel source surge. Many heat supply facility as well as power plants switches over from nonrenewable fuel source to biomass fuel.



To motivate the power plant to utilize biomass energy, Sweden government introduced electrical power quota system. This plan calls for the power suppliers to have certain part of electricity generated by renewable energy. For every single 1MWh electrical power, the federal government will certainly provide tax alleviation based on the biomass power amount.



Sweden wood pellet fuel shedding tool

Sweden wood pellet burning modern technology is in the leading placement. There have actually been over 20 pellet burner makers, over 50 kinds of wood pellet boilers, 120,000 sets of pellet boilers, 20,000 collections of pellet stoves.
