Sweden biomass pellet fuel market evaluation<br>
Sweden is one of the world's biggest wood pellet fuel manufacturer as well as consumer. It's wood pellet production technology, market policy, as well as market design project. In this passage, I will certainly do comprehensive analysis on Sweden biomass pellet fuel industry, as well as exercise some beneficial experiences.



Intro

In the 1970s, numerous countries have actually made plans to advertise biomass energy as a method to manage power dilemma and also setting contamination. Ever since, biomass power sector has created rapidly, and also the modern technology keep improving.



Due to the lack of mineral resources, Sweden's economic situation suffered terrific loss in last century. To make sure nationwide power protection, Sweden government aim to establish renewable resource.



Biomass pellet fuel has the attributes of high burning performance, low ash material, absolutely no carbon discharge, simple transport, which has actually been prominent in Europe as well as The United States And Canada. With bountiful forestry sources, Sweden pay much interest to the growth of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel usage, which matures at the speed of 8-10%.



Sweden forestry sources as well as biomass products

Sweden has plentiful forestry resources. The forest covers 64% of the acreage, with 51% possessed by people, 24% by huge wood business, and also 25% by countries and other public organizations. Besides, the forestry expands by 100 million loads annually, and also the deforestation quantity is 92.4 million bunches. The major forestry markets are wood processing, paper handling, and also power wood. The wood products for making biomass energy generally come from the 3 industries above, regarding 23.48 m3.



Raw materials of wood pellets

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



With even more firms engaging in biomass fuel production, the competitors on the raw products come to be much more strong. As the plant straws in Sweden are in scattered distribution, they are hard to gather as well as process. So some producers as well as institutes are developing brand-new materials like peat and energy plants.



Wood pellet manufacturing technology as well as equipment

The pellet molding modern technology has actually matured in Sweden. Nowadays, it has achieved commercial and market manufacturing. The production process features high automation, requiring less operators. richi pellet mill presented the wood pellet manufacturing procedure.



Drying: generally, the wetness web content of sawdust is around 50%. A drum clothes dryer can decrease the wetness material to 9-12% to ensure that it is received making pellets.


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

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

Pellet molding: many wood pellet factories use upright type ring pass away pellet machine. The production 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 equipment go to the temperature level of 100 ℃. Pellets under this problem are simple to break and troublesome for transportation. A counter-flow cooler can cool off the wood pellets in a modest means.

Packaging: the cooled pellets need to be categorized and packaged according to consumers' need. Tiny bags are 16kg, huge bags are 900kg. For big consumers like nuclear power plant, the wood pellets are moved by vehicles as well as ships in bulks.

Biomass pellets category as well as application

In 1999, Sweden federal government published the requirement of wood pellet fuel, in which they are classified right into 3 courses. The fabulous has excellent quality. They can be made use of in residential small burners as well as stoves.The 2nd and also 3rd don't have high quality. They are made use of by large industrial consumers.



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



Wood pellet fuel can be applied in tiny central heating boilers, medium-scale as well as large home heating supply facility as well as nuclear power plant. Presently, Sweden has 60% of wood pellet fuel for tiny as well as average heating central heating boilers and local home heating supply facility, as well as 40% for big heating supply center 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 exhaust tax obligation, these home heating plant turn to biomass fuel from coal. In the last decade, the quantity of biomass fuel for heating grows from 1.1 PJ to 57PJ. Presently, about 400 local heating plant has actually embraced wood pellet fuel.



Given that the mid 1990s, domestic wood pellet market has actually made excellent progress. In the last decades, the use of residential heating wood pellets grows rapidly. Presently, Sweden has 200,000 households using wood pellet central heating boilers, 40,000 families utilizing wood pellet ranges.



Sweden biomass energy development goal as well as plan

To promote the constant development of biomass power, Sweden has actually made a collection of legislations as well as policies. To guarantee the execute of these plans, the government also made many practical supervision actions and also necessary sector standard.



Sweden not only satisfy the commitment specified Kyoto Protocol that reduced greenhouse emission by 8%, however likewise set its own advancement goal of biomass power. In 2006, the Preacher for lasting advancement department declared that Sweden will totally use biofuels and also quit utilizing oil, and also become the very first country that totally rely upon renewable resource.



By 2020, Sweden will certainly increase its percentage of renewable energy to 50%, the usage ratio of renewable resource in transport market to 10%, power performance by 20%, and cut the exhaust of greenhouse gas by 40%.



Wood pellet fuel motivation plan

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



Considering that 1975, Sweden spends 36 million Euro from government spending plan to sustain biomass modern technology growth. From 1997 to 2002, the government supplied 25% financial investment subsidy to biomass cogeneration jobs. From 2004-2006, the federal government offered 1350 Euros for citizens that use biomass heater.



Sweden generally lay high tax obligation on fuels, energies, CARBON DIOXIDE, SO2, etc. To promote the development of biomass power, to exempt all tax obligations on biomass jobs. In 1991, Sweden federal government starts to lay tax obligation on CO2 discharge, that makes the price of oil as well as nonrenewable fuel source increase. A lot of heat supply facility as well as power plants switches from nonrenewable fuel source to biomass fuel.



To motivate the nuclear power plant to use biomass power, Sweden federal government presented electrical power quota system. This policy requires the power suppliers to have particular portion of electrical power produced by renewable resource. For every 1MWh electrical power, the government will give tax obligation alleviation based upon the biomass power amount.



Sweden wood pellet fuel shedding device

Sweden wood pellet melting innovation is in the leading placement. There have actually mored than 20 pellet burner makers, over 50 types of wood pellet boilers, 120,000 sets of pellet central heating boilers, 20,000 sets of pellet ranges. As there are still many households using electric home heating, the pellet boilers have substantial possibility.
