Sweden biomass pellet fuel industry analysis<br>
Sweden is one of the globe's largest wood pellet fuel producer and consumer. It's wood pellet production innovation, sector policy, and market design project. In this passage, I will certainly do extensive evaluation on Sweden biomass pellet fuel market, as well as exercise some beneficial experiences.



Introduction

In the 1970s, many nations have made plans to advertise biomass energy as a way to handle energy situation and setting pollution. Ever since, biomass energy sector has actually established rapidly, and also the modern technology keep enhancing.



Due to the absence of mineral sources, Sweden's economy experienced great loss in last century. To guarantee national energy safety, Sweden federal government make every effort to create renewable resource.



Biomass pellet fuel has the attributes of high burning effectiveness, low ash content, absolutely no carbon exhaust, simple transport, which has been preferred in Europe and North America. With plentiful forestry resources, Sweden pay much attention to the advancement of biomass pellet fuel. Sweden occupies 20% of the world's biomass fuel consumption, which grows up at the rate of 8-10%.



Sweden forestry sources as well as biomass products

Sweden has bountiful forestry sources. The forest covers 64% of the acreage, with 51% had by people, 24% by large wood companies, as well as 25% by nations and other public organizations. Besides, the forestry expands by 100 million heaps yearly, as well as the logging amount is 92.4 million lots. The significant forestry industries are wood handling, paper handling, as well as power wood. The wood materials for making biomass power mainly originated from the 3 industries above, about 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, agriculture residues, power forestry) uses up 7%. Some tiny wood pellet manufacturing facility are built base on chipboard, furnishings and also sawdust mills.



With more firms participating in biomass fuel production, the competition on the raw products end up being much more tough. As the plant straws in Sweden remain in scattered distribution, they are difficult to gather and also process. So some producers as well as institutes are establishing brand-new products like peat and also power crops.



Wood pellet making modern technology and equipment

The pellet molding technology has actually developed in Sweden. Nowadays, it has attained commercial as well as market manufacturing. The manufacturing process features high automation, needing less operators. The picture below showed the wood pellet production procedure.



Drying: generally, the dampness content of sawdust is around 50%. https://medium.com/@sales_92718/what-are-the-benefits-of-wood-pellet-mill-46dda3f7135f can lower the wetness web content to 9-12% to ensure that it is gotten approved for making pellets.

Crushing: the size of raw materials need to be under 5mm. They require a hammer mill to decrease the size.

Conditioning: add high-heat vapor to the raw products and soften the cellulous in it. More than half of the pellet fuel manufacturers have conditioning process in production.

Pellet molding: the majority of wood pellet manufacturing facilities utilize upright type ring pass away pellet equipment. The production capacity of one maker 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 machine are at the temperature of 100 ℃. Pellets under this condition are easy to break and also bothersome for transport. A counter-flow colder can cool down the wood pellets in a moderate method.

Packaging: the cooled down pellets need to be identified and packaged according to clients' demand. Tiny bags are 16kg, huge bags are 900kg. For large clients like nuclear power plant, the wood pellets are carried by vehicles and ships wholesale.

Biomass pellets classification as well as application

In 1999, Sweden federal government released the requirement of wood pellet fuel, in which they are identified right into 3 classes. The excellent has top quality. They can be made use of in domestic tiny heaters and stoves.The second and third do not have premium quality. They are made use of by large commercial clients.



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



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



From the 1970s to the 1990s, Sweden local home heating plant take on coal to replace oil. After the pass of carbon dioxide exhaust tax obligation, these home heating plant resort to biomass fuel from coal. In the last years, the amount of biomass fuel for heating expands from 1.1 PJ to 57PJ. Currently, concerning 400 local home heating plant has taken on wood pellet fuel.




Because the mid 1990s, domestic wood pellet sector has actually made wonderful development. In the last decades, the use of residential heating wood pellets grows rapidly. Currently, Sweden has 200,000 households making use of wood pellet boilers, 40,000 families utilizing wood pellet stoves.



Sweden biomass energy development objective as well as policy

To advertise the continuous advancement of biomass power, Sweden has made a collection of regulations as well as plans. To make sure the carry out of these policies, the government likewise made numerous viable supervision steps and obligatory market standard.



Sweden not just satisfy the responsibility stated Kyoto Protocol that cut greenhouse exhaust by 8%, however also set its own development goal of biomass energy. In 2006, the Priest for sustainable growth division asserted that Sweden will totally make use of biofuels as well as quit utilizing oil, and become the initial nation that totally count on renewable energy.



By 2020, Sweden will boost its percentage of renewable resource to 50%, the usage proportion of renewable energy in transport sector to 10%, energy performance by 20%, and reduced the discharge of greenhouse gas by 40%.



Wood pellet fuel motivation plan

Sweden has actually executed high price acquisition, financial investment subsidies, tax obligation decrease and also exemption, quota system and also other biomass energy incentive plan.



Since 1975, Sweden spends 36 million Euro from federal government budget to support biomass innovation advancement. From 1997 to 2002, the government offered 25% investment aid to biomass cogeneration jobs. From 2004-2006, the federal government gave 1350 Euros for locals who use biomass furnace.



Sweden generally lay high tax on fuels, energies, CO2, SO2, etc. To advertise the growth of biomass power, to spare all taxes on biomass projects. In 1991, Sweden government starts to lay tax on CO2 discharge, that makes the cost of oil and also fossil fuel increase. Numerous warm supply center and nuclear power plant switches from fossil fuel to biomass fuel.




To motivate the nuclear power plant to use biomass energy, Sweden government presented electric power quota system. This policy needs the power vendors to have particular portion of power generated by renewable resource. For every single 1MWh electrical power, the federal government will provide tax obligation relief based on the biomass power quantity.



Sweden wood pellet fuel melting tool

Sweden wood pellet shedding innovation is in the leading position. There have actually been over 20 pellet burner makers, over 50 kinds of wood pellet boilers, 120,000 sets of pellet boilers, 20,000 sets of pellet ovens.
