Sweden biomass pellet fuel market evaluation<br>
Sweden is among the world's largest wood pellet fuel manufacturer as well as customer. It's wood pellet manufacturing modern technology, sector policy, as well as market model project. In this flow, I will do comprehensive evaluation on Sweden biomass pellet fuel sector, as well as exercise some useful experiences.



Intro

In the 1970s, several nations have actually made policies to promote biomass power as a means to handle energy crisis and setting air pollution. Ever since, biomass energy market has created swiftly, and also the innovation maintain boosting.



As a result of the lack of mineral resources, Sweden's economy endured great loss in last century. To make sure national power security, Sweden federal government strive to create renewable resource.



Biomass pellet fuel has the features of high burning performance, low ash content, absolutely no carbon discharge, easy transportation, which has been preferred in Europe as well as The United States And Canada. With bountiful forestry resources, Sweden pay much attention to the development of biomass pellet fuel. Sweden occupies 20% of the globe's biomass fuel consumption, which grows up at the speed of 8-10%.



Sweden forestry sources and also biomass materials

Sweden has bountiful forestry resources. The woodland covers 64% of the acreage, with 51% had by people, 24% by huge wood companies, as well as 25% by countries and also other public organizations. Besides, the forestry expands by 100 million tons annually, and also the deforestation quantity is 92.4 million tons. The major forestry sectors are wood processing, paper handling, and energy wood. The wood materials for making biomass power mainly come from the 3 industries above, concerning 23.48 m3.



Basic material of wood pellets

Of the raw materials for making wood pellets, wood shavings use up 53%, sawdust 35%, and wood chips 5%, others (barks, farming deposits, energy forestry) uses up 7%. Some tiny wood pellet manufacturing facility are constructed base on chipboard, furniture as well as sawdust mills.



With more business taking part in biomass fuel manufacturing, the competition on the raw materials come to be much more strong. As the plant straws in Sweden are in scattered distribution, they are tough to collect and refine. So some producers as well as institutes are creating brand-new products like peat as well as power crops.




Wood pellet producing technology and equipment

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



Drying: typically, the wetness material of sawdust is around 50%. A drum dryer can decrease the dampness web content to 9-12% so that it is qualified for making pellets.

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

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

Pellet molding: many wood pellet manufacturing facilities use vertical type ring pass away pellet maker. The manufacturing capability of one machine 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 go to the temperature level of 100 ℃. Pellets under this condition are very easy to damage as well as troublesome for transport. A counter-flow colder can cool off the wood pellets in a moderate method.

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

Biomass pellets classification as well as application

In 1999, Sweden government released the criterion of wood pellet fuel, in which they are identified into 3 courses. The first class has high quality. They can be used in residential tiny heaters as well as stoves.The second and third do not have excellent quality. They are used by huge industrial clients.



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



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



From the 1970s to the 1990s, Sweden local heating plant adopt coal to replace oil. After the establish of CO2 emission tax obligation, these heating plant resort to biomass fuel from coal. In the last decade, the amount of biomass fuel for heating expands from 1.1 PJ to 57PJ. Currently, concerning 400 local home heating plant has actually adopted wood pellet fuel.




Considering that the mid 1990s, residential wood pellet market has actually made wonderful development. In the last decades, making use of residential home heating wood pellets proliferates. Presently, Sweden has 200,000 households utilizing wood pellet boilers, 40,000 family members making use of wood pellet ranges.



Sweden biomass energy growth objective and also plan

To advertise the continual growth of biomass power, Sweden has made a series of legislations as well as plans. To ensure the execute of these policies, the federal government also made numerous practical supervision procedures and also obligatory sector criterion.



Sweden not only meet the obligation stipulated Kyoto Protocol that cut greenhouse emission by 8%, however additionally established its very own growth objective of biomass energy. In 2006, the Minister for lasting growth department asserted that Sweden will totally use biofuels and quit utilizing oil, and come to be the very first country that completely count on renewable energy.



By 2020, Sweden will enhance its percentage of renewable resource to 50%, the usage proportion of renewable resource in transport market to 10%, energy effectiveness by 20%, as well as reduced the emission of greenhouse gas by 40%.



Wood pellet fuel motivation policy

Sweden has actually carried out high rate purchase, financial investment aids, tax obligation decrease and exception, quota system and other biomass power incentive plan.



Because 1975, Sweden invests 36 million Euro from federal government spending plan to support biomass modern technology development. From extruder pelletizer to 2002, the federal government supplied 25% financial investment subsidy to biomass cogeneration jobs. From 2004-2006, the federal government supplied 1350 Euros for homeowners that use biomass heater.



Sweden generally lay high tax on fuels, energies, CARBON DIOXIDE, SO2, etc. To promote the growth of biomass power, to excuse all taxes on biomass tasks. In chicken manure pellet machine , Sweden federal government begins to lay tax on carbon dioxide discharge, that makes the price of oil as well as fossil fuel increase. Numerous heat supply facility and also nuclear power plant switches from nonrenewable fuel source to biomass fuel.



To encourage the nuclear power plant to use biomass energy, Sweden government introduced electrical power quota system. This policy calls for the power vendors to have particular section of electrical energy created by renewable energy. For every 1MWh electricity, the federal government will certainly give tax obligation relief based on the biomass power amount.



Sweden wood pellet fuel burning tool
