Sweden biomass pellet fuel sector evaluation<br>
Sweden is just one of the world's biggest wood pellet fuel producer and also customer. It's wood pellet production modern technology, sector policy, and market version project. In this passage, I will certainly do extensive evaluation on Sweden biomass pellet fuel sector, and exercise some beneficial experiences.



Introduction

In the 1970s, several countries have made plans to advertise biomass power as a method to handle power situation and also atmosphere air pollution. Since then, biomass power sector has actually developed swiftly, and also the modern technology keep improving.



As a result of the absence of mineral sources, Sweden's economic climate experienced wonderful loss in last century. To ensure national power security, Sweden government aim to establish renewable resource.




Biomass pellet fuel has the features of high burning performance, reduced ash material, zero carbon emission, simple transportation, which has actually been preferred in Europe as well as North America. With abundant forestry sources, Sweden pay much attention to the advancement of biomass pellet fuel. Sweden takes up 20% of the globe's biomass fuel consumption, which matures at the rate of 8-10%.



Sweden forestry sources and biomass products

Sweden has bountiful forestry sources. The forest covers 64% of the land area, with 51% possessed by individuals, 24% by large wood firms, and 25% by nations as well as other public organizations. Besides, the forestry expands by 100 million loads each year, and the logging amount is 92.4 million lots. The significant forestry industries are wood handling, paper handling, and also power wood. The wood products for making biomass power generally originated from the 3 sectors above, concerning 23.48 m3.



Raw materials of wood pellets

Of the raw materials for making wood pellets, wood shavings use up 53%, sawdust 35%, as well as wood chips 5%, others (barks, agriculture deposits, power forestry) occupies 7%. Some little wood pellet factory are built base upon chipboard, furnishings as well as sawdust mills.



With even more business taking part in biomass fuel production, the competitors on the raw products become a lot more strong. As the crop straws in Sweden are in scattered distribution, they are tough to gather as well as process. So some manufacturers as well as institutes are developing brand-new materials like peat and also energy plants.



Wood pellet producing modern technology and also equipment

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



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

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

Conditioning: include high-heat steam to the raw materials and soften the cellulous in it. Over half of the pellet fuel producers have conditioning procedure in manufacturing.

Pellet molding: most wood pellet manufacturing facilities utilize vertical kind ring pass away pellet machine. The manufacturing ability of one machine 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 are at the temperature of 100 ℃. Pellets under this condition are very easy to break as well as inconvenient for transportation. A counter-flow colder can cool the wood pellets in a modest method.

Packing: the cooled down pellets require to be classified as well as packaged according to consumers' demand. Small bags are 16kg, large bags are 900kg. For big clients like power plant, the wood pellets are delivered by vehicles and also ships wholesale.

Biomass pellets category and application

In 1999, Sweden government released the requirement of wood pellet fuel, in which they are classified right into 3 courses. The first class has premium quality. They can be utilized in residential little burners and stoves.The second and also 3rd don't have premium quality. They are utilized by large industrial consumers.



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



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



From the 1970s to the 1990s, Sweden local heating plant take on coal to change oil. After the establish of CO2 discharge tax, these heating plant resort to biomass fuel from coal. In the last decade, the quantity of biomass fuel for heating expands from 1.1 PJ to 57PJ. Presently, regarding https://commaful.com/play/carmenrichi/which-fowl-feed-pellet-making-equipment-is-better/ has actually embraced wood pellet fuel.



Given that the mid 1990s, domestic wood pellet sector has actually made wonderful progression. In the last years, using domestic home heating wood pellets proliferates. Presently, Sweden has 200,000 family members making use of wood pellet central heating boilers, 40,000 family members making use of wood pellet stoves.



Sweden biomass energy advancement goal as well as policy

To promote the continuous advancement of biomass power, Sweden has actually made a series of legislations and also policies. To ensure the apply of these policies, the federal government also made many possible guidance actions as well as compulsory sector standard.



Sweden not only fulfill the responsibility stated Kyoto Method that reduced greenhouse exhaust by 8%, however also set its very own advancement objective of biomass power. In 2006, the Priest for sustainable development department declared that Sweden will completely make use of biofuels and stop using oil, and also end up being the initial country that completely rely upon renewable resource.



By 2020, Sweden will certainly enhance its proportion of renewable energy to 50%, the usage proportion of renewable resource in transportation sector to 10%, power performance by 20%, as well as reduced the exhaust of greenhouse gas by 40%.



Wood pellet fuel reward plan

Sweden has performed high rate procurement, financial investment subsidies, tax decrease as well as exemption, quota system and also various other biomass energy motivation policy.



Considering that 1975, Sweden spends 36 million Euro from federal government spending plan to support biomass modern technology development. From 1997 to 2002, the government offered 25% investment aid to biomass cogeneration projects. From 2004-2006, the government supplied 1350 Euros for locals that make use of biomass heating unit.



Sweden typically lay high tax on fuels, energies, CARBON DIOXIDE, SO2, etc. To advertise the advancement of biomass energy, to exempt all tax obligations on biomass tasks. In 1991, Sweden government starts to lay tax obligation on carbon dioxide emission, which makes the price of oil and also fossil fuel rise. So many warm supply facility and also nuclear power plant switches from fossil fuel to biomass fuel.



To motivate the power plant to utilize biomass energy, Sweden federal government introduced electrical power quota system. This policy requires the power vendors to have specific section of electrical energy produced by renewable resource. For every single 1MWh electrical power, the federal government will give tax relief based on the biomass power quantity.



Sweden wood pellet fuel shedding tool

Sweden wood pellet shedding modern technology remains in the leading position. There have actually been over 20 pellet heater suppliers, over 50 types of wood pellet boilers, 120,000 sets of pellet boilers, 20,000 sets of pellet stoves.
