Sweden biomass pellet fuel industry evaluation<br>
Sweden is among the globe's largest wood pellet fuel manufacturer and consumer. It's wood pellet production technology, sector plan, as well as market model project. In this flow, I will do comprehensive analysis on Sweden biomass pellet fuel sector, as well as work out some helpful experiences.



Introduction

In the 1970s, numerous nations have made policies to promote biomass energy as a way to manage energy dilemma and atmosphere air pollution. Since then, biomass energy sector has created rapidly, as well as the innovation keep improving.



As a result of the lack of mineral sources, Sweden's economic situation endured fantastic loss in last century. To guarantee nationwide energy protection, Sweden federal government aim to create renewable resource.



Biomass pellet fuel has the attributes of high burning effectiveness, reduced ash material, no carbon discharge, very easy transport, which has actually been popular in Europe and also The United States And Canada. With homemade wood pellet machine , Sweden pay much interest to the advancement of biomass pellet fuel. Sweden occupies 20% of the world's biomass fuel intake, which grows up at the speed of 8-10%.



Sweden forestry resources and also biomass materials

Sweden has plentiful forestry sources. The woodland covers 64% of the acreage, with 51% owned by individuals, 24% by huge wood business, and also 25% by countries as well as other public companies. Besides, the forestry expands by 100 million tons annually, and also the deforestation quantity is 92.4 million heaps. The significant forestry markets are wood processing, paper processing, as well as energy wood. The wood materials for making biomass power mainly come from the 3 sectors above, about 23.48 m3.



Basic material of wood pellets

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



With even more business engaging in biomass fuel manufacturing, the competition on the raw materials come to be a lot more intense. As the plant straws in Sweden remain in scattered distribution, they are tough to accumulate and process. So some manufacturers and also institutes are establishing new products like peat as well as power plants.



Wood pellet manufacturing innovation and also tools

The pellet molding innovation has actually grown in Sweden. Nowadays, it has actually accomplished industrial and market production. The production procedure includes high automation, calling for less drivers. The picture listed below presented the wood pellet production process.



Drying out: generally, the moisture content of sawdust is around 50%. A drum clothes dryer can reduce the dampness content to 9-12% to make sure that it is gotten approved for making pellets.

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

Conditioning: include high-heat heavy steam to the raw products and also soften the cellulous in it. Majority of the pellet fuel makers have conditioning procedure in production.

Pellet molding: many wood pellet factories utilize upright kind ring die pellet equipment. The production capacity of one equipment 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 problem are simple to damage and inconvenient for transportation. A counter-flow cooler can cool down the wood pellets in a moderate method.

Packaging: the cooled pellets need to be identified and packaged according to customers' requirement. Little bags are 16kg, big bags are 900kg. For huge clients like nuclear power plant, the wood pellets are moved by trucks and ships in bulks.

Biomass pellets category and also application

In 1999, Sweden federal government published the requirement of wood pellet fuel, in which they are classified into 3 classes. The first-rate has premium quality. They can be used in domestic tiny burners and stoves.The second as well as third don't have top quality. They are made use of by huge industrial consumers.



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



Wood pellet fuel can be used in little central heating boilers, medium-scale and massive heating supply facility as well as power plant. Currently, Sweden has 60% of wood pellet fuel for tiny and also average heating boilers and also regional home heating supply facility, and 40% for huge heating supply center as well as co-firing 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 rely on biomass fuel from coal. In the last years, the amount of biomass fuel for home heating grows from 1.1 PJ to 57PJ. Currently, concerning 400 regional heating plant has actually adopted wood pellet fuel.



Because the mid 1990s, residential wood pellet sector has made great progress. In price of pellet making machine , making use of residential home heating wood pellets proliferates. Currently, Sweden has 200,000 households making use of wood pellet central heating boilers, 40,000 families utilizing wood pellet ranges.



Sweden biomass energy growth goal as well as policy

To advertise the constant advancement of biomass power, Sweden has actually made a series of legislations and also policies. To make certain the apply of these policies, the government additionally made many viable guidance procedures and obligatory industry requirement.



Sweden not just meet the responsibility stated Kyoto Protocol that cut greenhouse discharge by 8%, however also set its very own advancement goal of biomass power. In 2006, the Priest for lasting development division declared that Sweden will completely use biofuels and also quit making use of oil, and end up being the very first nation that entirely rely on renewable energy.



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



Wood pellet fuel incentive plan

Sweden has actually carried out high cost purchase, financial investment aids, tax obligation reduction and also exception, quota system and other biomass power reward plan.




Since 1975, Sweden invests 36 million Euro from government spending plan to sustain biomass modern technology growth. From 1997 to 2002, the federal government provided 25% investment subsidy to biomass cogeneration tasks. From 2004-2006, the government provided 1350 Euros for locals that use biomass furnace.



Sweden usually lay high tax on fuels, energies, CARBON DIOXIDE, SO2, and so on. To promote the advancement of biomass power, to excuse all taxes on biomass jobs. In 1991, Sweden federal government begins to lay tax obligation on carbon dioxide discharge, that makes the rate of oil and also nonrenewable fuel source increase. A lot of warmth supply facility and also nuclear power plant switches from nonrenewable fuel source to biomass fuel.




To urge the power plant to utilize biomass energy, Sweden government presented electrical power quota system. This policy requires the power distributors to have particular part of electricity produced by renewable resource. For every single 1MWh electrical energy, the federal government will certainly give tax obligation relief based upon the biomass power quantity.



Sweden wood pellet fuel burning gadget

Sweden wood pellet shedding modern technology is in the leading setting. There have actually been over 20 pellet burner suppliers, over 50 kinds of wood pellet central heating boilers, 120,000 sets of pellet central heating boilers, 20,000 collections of pellet ranges.
