Sweden biomass pellet fuel market evaluation<br>
Sweden is one of the globe's largest wood pellet fuel manufacturer and also customer. It's wood pellet manufacturing modern technology, industry plan, and also market model are prominent. In this flow, I will do comprehensive evaluation on Sweden biomass pellet fuel industry, as well as exercise some useful experiences.



Intro

In the 1970s, lots of nations have made policies to advertise biomass power as a method to cope with energy situation and also environment pollution. Ever since, biomass energy industry has established rapidly, and also the technology keep improving.



Because of the lack of mineral sources, Sweden's economic climate suffered terrific loss in last century. To ensure nationwide power security, Sweden government aim to establish renewable energy.



Biomass pellet fuel has the features of high burning effectiveness, low ash web content, no carbon exhaust, easy transport, which has been preferred in Europe and also North America. With plentiful forestry sources, Sweden pay much attention to the growth of biomass pellet fuel. Sweden takes up 20% of the world's biomass fuel usage, which grows up at the speed of 8-10%.



Sweden forestry sources and biomass materials

Sweden has bountiful forestry resources. The woodland covers 64% of the acreage, with 51% owned by people, 24% by large wood firms, and also 25% by countries and also various other public organizations. Besides, the forestry expands by 100 million heaps yearly, and also the logging amount is 92.4 million tons. The significant forestry markets are wood processing, paper processing, and power wood. The wood materials for making biomass energy mostly come from the 3 sectors above, concerning 23.48 m3.



Resources of wood pellets

Of the raw products for making wood pellets, wood shavings occupy 53%, sawdust 35%, as well as wood chips 5%, others (barks, agriculture deposits, energy forestry) takes up 7%. Some little wood pellet manufacturing facility are developed base upon chipboard, furniture and sawdust mills.



With even more companies participating in biomass fuel manufacturing, the competition on the raw materials come to be extra fierce. As the plant straws in Sweden remain in scattered circulation, they are tough to gather and also process. So some manufacturers and institutes are creating new materials like peat and energy crops.



Wood pellet manufacturing modern technology and also devices

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



Drying out: typically, the dampness web content of sawdust is around 50%. A drum dryer can reduce the moisture 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 minimize the dimension.

Conditioning: add high-heat steam to the raw products and also soften the cellulous in it. Majority of the pellet fuel producers have conditioning process in manufacturing.

Pellet molding: most wood pellet manufacturing facilities use upright kind ring die pellet maker. The production capability of one maker is 2-4ton/ h. The service life of ring die is 2000-3000h, while the roller can last 1000-1500h.

Air conditioning: the wood pellets extruded out from the pellet device are at the temperature of 100 ℃. Pellets under this problem are very easy to break and troublesome for transportation. A counter-flow cooler can cool the wood pellets in a modest method.

Packing: the cooled pellets need to be categorized as well as packaged according to customers' need. Little bags are 16kg, large bags are 900kg. For big customers like nuclear power plant, the wood pellets are moved by trucks and ships wholesale.

Biomass pellets category as well as application

In 1999, Sweden federal government released the requirement of wood pellet fuel, in which they are classified into 3 classes. The first class has high quality. They can be used in domestic little heaters and also stoves.The second and 3rd do not have top quality. They are utilized by big commercial clients.



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



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



From the 1970s to the 1990s, Sweden local home heating plant take on coal to change oil. After the pass of carbon dioxide emission tax obligation, these home heating plant turn to biomass fuel from coal. In the last decade, the quantity of biomass fuel for heating expands from 1.1 PJ to 57PJ. Currently, regarding 400 regional heating plant has actually adopted wood pellet fuel.



Considering that the mid 1990s, residential wood pellet market has made fantastic development. In the last years, making use of domestic heating wood pellets grows rapidly. Currently, Sweden has 200,000 family members utilizing wood pellet central heating boilers, 40,000 family members using wood pellet ovens.



Sweden biomass energy advancement objective as well as plan

To promote the continuous development of biomass energy, Sweden has made a collection of legislations and also plans. To ensure the execute of these policies, the federal government additionally made several practical guidance actions and also obligatory sector requirement.



Sweden not only accomplish the obligation stated Kyoto Method that cut greenhouse exhaust by 8%, but also established its very own growth goal of biomass power. In 2006, the Minister for lasting growth division claimed that Sweden will completely make use of biofuels as well as stop utilizing oil, as well as end up being the first nation that completely count on renewable energy.




By 2020, Sweden will certainly boost its proportion of renewable resource to 50%, the use proportion of renewable energy in transportation market to 10%, energy efficiency by 20%, and reduced the emission of greenhouse gas by 40%.



Wood pellet fuel incentive policy

Sweden has actually performed high rate acquisition, financial investment aids, tax obligation decrease and also exception, quota system and also other biomass power motivation policy.



Because 1975, Sweden spends 36 million Euro from government spending plan to sustain biomass innovation development. From 1997 to 2002, the federal government offered 25% investment aid to biomass cogeneration tasks. From 2004-2006, the government gave 1350 Euros for residents that use biomass furnace.



Sweden normally lay high tax on fuels, energies, CO2, SO2, and so on. To promote the advancement of biomass power, to spare all tax obligations on biomass projects. In 1991, Sweden government begins to lay tax on CO2 discharge, that makes the price of oil and nonrenewable fuel source increase. So many warm supply facility and also nuclear power plant switches from nonrenewable fuel source to biomass fuel.



To urge the power plant to make use of biomass energy, Sweden federal government presented electric power quota system. This plan needs the power distributors to have specific section of power created by renewable resource. For each 1MWh electrical power, the federal government will provide tax relief based on the biomass power amount.
