Sweden biomass pellet fuel sector analysis<br>
Sweden is among the globe's largest wood pellet fuel manufacturer as well as consumer. It's wood pellet manufacturing modern technology, market plan, and also market version project. In this flow, I will do comprehensive analysis on Sweden biomass pellet fuel market, and exercise some valuable experiences.



Introduction

In the 1970s, numerous nations have actually made plans to promote biomass power as a way to manage energy dilemma and atmosphere pollution. Ever since, biomass energy industry has actually developed quickly, and the innovation keep boosting.



As a result of the lack of mineral sources, Sweden's economy suffered fantastic loss in last century. To make certain nationwide power security, Sweden government strive to establish renewable resource.



Biomass pellet fuel has the features of high burning efficiency, low ash content, no carbon exhaust, very easy transportation, which has actually been popular in Europe and North America. With abundant forestry resources, Sweden pay much attention to the development of biomass pellet fuel. Sweden uses up 20% of the globe's biomass fuel usage, which matures at the speed of 8-10%.



Sweden forestry resources and biomass materials

Sweden has bountiful forestry sources. The woodland covers 64% of the acreage, with 51% had by people, 24% by big wood companies, and also 25% by countries and also other public companies. Besides, the forestry grows by 100 million tons every year, and the deforestation quantity is 92.4 million bunches. The significant forestry sectors are wood handling, paper processing, and energy wood. The wood materials for making biomass power primarily originated from the 3 sectors above, regarding 23.48 m3.




Resources of wood pellets

Of the raw products for making wood pellets, wood shavings use up 53%, sawdust 35%, and also wood chips 5%, others (barks, agriculture residues, power forestry) occupies 7%. Some small wood pellet factory are built base on chipboard, furnishings and also sawdust mills.



With even more firms taking part in biomass fuel manufacturing, the competition on the raw materials come to be extra tough. As the plant straws in Sweden are in scattered distribution, they are difficult to collect and also refine. So some producers and institutes are establishing brand-new products like peat as well as energy crops.



Wood pellet making technology as well as equipment

The pellet molding modern technology has actually matured in Sweden. Nowadays, it has achieved industrial and market production. The manufacturing procedure includes high automation, requiring much less operators. The picture below showed the wood pellet manufacturing process.



Drying: generally, the moisture content of sawdust is around 50%. A drum dryer can lower the moisture web content to 9-12% so that it is gotten approved for making pellets.

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

Conditioning: include high-heat vapor to the raw materials as well as soften the cellulous in it. More than half of the pellet fuel suppliers have conditioning procedure in manufacturing.

Pellet molding: the majority of wood pellet factories make use of upright kind ring die pellet device. The manufacturing capacity 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 maker are at the temperature level of 100 ℃. Pellets under this condition are easy to break as well as inconvenient for transportation. A counter-flow cooler can cool down the wood pellets in a modest way.

Packing: the cooled down pellets need to be identified as well as packaged according to consumers' requirement. Small bags are 16kg, large bags are 900kg. For huge clients like power plant, the wood pellets are transported by trucks and ships in bulks.

Biomass pellets category as well as application

In 1999, Sweden federal government published the criterion of wood pellet fuel, in which they are classified right into 3 courses. The excellent has premium quality. They can be used in residential small burners as well as stoves.The second as well as third don't have excellent quality. They are made use of by huge commercial customers.



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



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



From the 1970s to the 1990s, Sweden local home heating plant embrace coal to replace oil. After the enact of CO2 exhaust tax obligation, these home heating plant look to biomass fuel from coal. In the last years, the amount of biomass fuel for heating grows from 1.1 PJ to 57PJ. Presently, regarding 400 regional home heating plant has adopted wood pellet fuel.



Since the mid 1990s, domestic wood pellet industry has actually made wonderful progress. In the last decades, making use of residential home heating wood pellets grows rapidly. Currently, Sweden has 200,000 households utilizing wood pellet central heating boilers, 40,000 family members utilizing wood pellet ranges.



Sweden biomass power advancement objective as well as plan

To advertise the continual advancement of biomass energy, Sweden has actually made a collection of regulations as well as plans. To guarantee the carry out of these policies, the federal government likewise made numerous practical guidance measures as well as obligatory sector requirement.



Sweden not only accomplish the obligation specified Kyoto Procedure that cut greenhouse discharge by 8%, however also set its very own growth objective of biomass power. In 2006, the Minister for lasting development division declared that Sweden will totally utilize biofuels as well as stop utilizing oil, and come to be the initial country that entirely depend on renewable energy.



By 2020, Sweden will certainly increase its percentage of renewable resource to 50%, the usage ratio of renewable energy in transportation sector to 10%, energy effectiveness by 20%, and cut the discharge of greenhouse gas by 40%.



Wood pellet fuel motivation policy

Sweden has carried out high cost acquisition, investment subsidies, tax decrease as well as exception, quota system as well as various other biomass energy reward plan.



Since 1975, Sweden spends 36 million Euro from government spending plan to support biomass modern technology development. From 1997 to 2002, the federal government gave 25% financial investment aid to biomass cogeneration tasks. From 2004-2006, the government supplied 1350 Euros for homeowners that use biomass heating unit.



Sweden normally lay high tax obligation on fuels, powers, CO2, SO2, and so on. To advertise the advancement of biomass power, to spare all taxes on biomass jobs. In pellet filling machine , Sweden federal government starts to lay tax on carbon dioxide exhaust, which makes the price of oil as well as fossil fuel increase. Numerous heat supply center as well as power plants switches from fossil fuel to biomass fuel.



To urge the power plant to utilize biomass energy, Sweden government introduced electric power quota system. This policy needs the power suppliers to have certain part of electrical energy produced by renewable energy. For each 1MWh electricity, the government will provide tax relief based upon the biomass power amount.
